Removing rust at the fender, filling, sanding and lacquering, part 1

Hey, again a lot of time has passed by and I haven't published anything for quite a long time. I was busy with an intense repair of my right front fender. Scratching a bit on a rust bubble turned out to a total revision of the fender folding. And I decided to film everything. But as I'm speaking German in the video I decided to add some comments to a video of almost 30 minutes in total. A lot of work. So, enjoy here the first part of my body work on the W201. Switch on the comments on YouTube for the English subtitle.

Exchange of the ignition wires

Hi fellows,
a few months ago I saw many videos about typical issues and problems concerning the W201, taken from Kent Bergsma, an Mercedes expert for the classical cars. His good description about the "how to do it yourself" encouraged me to make an easy repair myself; the ignition wires. One wire, leading to the spark plug of the second cylinder, was broken. I guess it was a marten damage. The W201 ran well but I always thought that the engine might run a little better with a new set of ignition wires.

I ordered some from the manufacturer "Beru" and I started the work on a sunny Saturday noon. Watch my video below and enjoy the little DIY-picture-description with text comments.

Video presentation of my W201 190E 1.8, part 1

The last days I was quite busy with a video presentation about my W201. You know that I produced one for my W126 in 2010, so I thought I should do the same with my W201.
Enjoy the first part the presentation. As soon as I have a a bit more time I will add a subtitle to it. But it's quite a lot of work for a video of more than 30 minutes.

See here and now the first of three parts; my W201, the Baby-Benz!

Technical Inspection Authority (TÜV), part 3

Today I got my car back. I had to go there by bus ;) Well, the result of the Technical Inspection Authority still is after 25 years: no defects found. The emissions are o.k., the breaks are o.k., the steering is absolutely in very good shape and altogether the inspector and the mechanic were both pleasantly surprised. Here you can see the document concerning the inspection (it's written in German of course):

The certificate of the Technical Inspection Authority, the license to drive another two years

Well, the mechanic did some work though. But the repairs weren't relevant for the Technical Inspection Authority. The repairs were done because I wanted the car to run a little more smooth. That's why the mechanic exchanged the shock absorbers, the suspension springs and the two motor bearings.

one of the two new motor bearings

Now, the car is very tight on the street and feels even safer than before. So, it's done. No strange noise anymore (the mechanic didn't fix the exhaust holder, because in his opinion the holder was unnecessary anyway), a tight and good driving feeling and a motor that runs very soft and smooth because of its new bearings. It was worth it!

O.k., got another two years approval. Mission successful!

10.000 clicks - thanks!

I want to say "Thank you" for more than 10.000 clicks on my blog within only two months. This is great! I will try to keep you posted about everything related to the W126 and the W201 and other nice classic cars.

If you have good ideas and interesting subjects or reports about your Mercedes classic car, leave me a message and I will publish your contribution as well.

Technical Inspection Authority (TÜV), part 2

O.k., today I got the phone call from the mechanic. The Technical Inspection Authority hasn't found anything serious. Only one of the headlights has to be adjusted - that's it! Wow, 25 years old and the only thing is a simple adjustment issue. Great!

Nevertheless the mechanic is doing a little more than necessary because there are a few things that I don't like:

- the motor bearings will be exchanged: 105,00 Euro each
- the front springs and the shock absorbers will be exchanged, 440,00 Euro
- one exhaust holder is rotten and this was the reason why I could hear a clanging noise coming from under the car, 45,00 Euro
- fee for the Technical Inspection Authority and the emissions inspection, 105,00 Euro
- work time, 220,00 Euro

It's going to cost me a bit but I think that after having done all these things, the car is going to run just fine and smoothly again. Will let you know more soon. Stay tuned!

Technical Inspection Authority (TÜV), part 1

Every two years a used car in Germany has to go through a technical inspection to keep the operating approval, carried out from the Technical Inspection Authority. Now it's March and time for my W201 to pass it. On Wednesday I will bring it to the garage to get some advice from the repair shop foreman and to do some inspection of the car before the official inspector. Not sure what to expect. I can hear some noise coming from the catalyst, the gas pressure springs are not the best anymore and the springs themselves aren't either. In a few days I will let you know about the progress we've made. Stay tuned.

Puchasing tips with Kent Bergsma - 1984 to 1993 W201 190E and 190D

Have you ever heard of Kent Bergsma? He's a Mercedes DIY-expert and he has repaired an uncountable amount of Mercedes-Benz classics, oldtimers and youngtimers. I've always loved to watch his very informative videos even if they were produced to encourage the purchase of other more detailed videos or equipment that he built on his own. The following video is dedicated to the W201 and how to find the right one. There are much more videos of Kent Bergsma and I've watched almost all of them. I will present you a number of good ones here on my blog.

Loose gear knob, a simple rubber ring with strong impact

Since 2010 I noticed that the gear knob of the automatic transmission became more and more loose. It was difficult to distinguish between the position "D" and "N", means it looked like as if the knob was on position "N" but the transmission indeed was in position "D". Moving the knob felt like moving something unstable in a mixture of every possibilities. Very confusing.
Talking to some friends and reading in some forums led me to a very small rubber ring under the car that is in almost every case the reason for this described malfunction.

We drove the car on a ramp to check the bars and connections of the automatic transmission under the car.

The problem is mostly a small rubber ring between the shift bar coming from the shift knob and the bar to the transmission. After years of heat, cold and mechanic impact the rubber becomes more and more hard and crumbly. It breaks. As the two bars are connected with a nut and the rubber rings around it, the bars don't disconnect, even if the rubber ring falls off completely. The effect is that you have a very soft and unstable feeling while shifting the shift knob. It is possible that you can hear a metallic sound while moving the shift knob. And here is the responsible part:

On the left side you can see the broken rubber part. On the right side is the new one. Kind of different, isn't it?

On the following picture you can see the new installed rubber ring. We used some grease to get it into its position. This is the most difficult part because the ring sits quite tight.

It's kind of a puzzle repair and small hands have a clear advantage here because you don't have much space in the tunnel under the car. But the effect is wonderful. The gear knob is tight again and it feels as if the car was brand new. The exchanged piece itself is a cent-article and the effect is disproportionately great!

The W201 and the Deutsche Tourenwagen Meisterschaften

The DTM (Deutsche Tourenwagen Meisterschaften, German Touring Car Championship) made the W201 very popular. 1992 was the year of Mercedes: The AMG-Mercedes-Benz 190E 2.5-16 Evo 2 won the championship 16 times. Watch the video below to get an impression of the ghost of 1992!

YouTube-videoDTM Jahresfilm 1992 in 16:9 (Trailer DVD 822)

The magic three letters “DTM” once stood for “Deutsche Tourenwagen-Meisterschaft” (German Touring Car Championship). Today, they are the trademark of the most popular international touring car racing series. Its history began in the 1984 season with cars that were close to the production versions and culminated in a worldwide series for high-tech touring cars in 1996. After a three-season break the DTM, in 2000, celebrated its successful comeback with a trendsetting concept – fascinating technology at reasonable costs. Today, the series is regarded as the “pinnacle” of touring car racing and one of Europe’s leading sports events. (, February 15th 2015)

Additional note to the exchange of the thermostat switch

A few days ago I reported about the exchange of the 100°C-thermostat switch. Well, another reason for a non-functioning fan might be the fan itself. So you should check the ventilator by following these steps:

Pull off the connector of the thermostat switch as shown on the following picture.

This is the cable between the thermostat switch and the fan. If you disconnect it the electric circuit is open and the fan doesn't get electricity. Take a short cable and make a short circuit by plugging the two ends in the two openings of the connector.

If you start the engine now the fan should start immediately ventilating fast and relative to the engine speed. If this is the case you have proven that the fan is working fine and that a malfunction is probably caused by the thermostat switch.

Sanding and recoating the small wooden plank around the shift knob

In January 2013 I was so crazy and did a very difficult DIY job. Sanding and recoating the small wooden plank around the shift knob. I collected all available data from the internet and I started looking for the right products. Altogether it is a job with a great outcome. But take you time! Doing it too fast leads to air pockets or chipping. Click on the video below to watch this DIY in a time lapse.

Video about the exchange of the thermostat cover

CLICK HERE to watch the video about the exchange of the thermostat cover. The covers made of aluminum are more stable than the plastic ones. The plastic covery break and the sudden loss of cooling water can cause severe damage to the engine. The next days I will provide you with some more details and photos of the exchange. The video is a more artistic one.

Bruno Sacco - talking about his work life at Mercedes-Benz

Bruno Sacco,
picture taken from

Bruno Sacco was born November 12, 1933 in Udine. The designer was one of the most important designers working for Mercedes-Benz. He was responsible for the design of many classics that we call our own and that we still find timeless (W126, W201 and others). "Gutes Design erkennt man durch das Fehlen von Schnickschnack!", that means "You can recognize good design by the lack of knickknacks!" That describes just perfectly his work. In the following video Bruno Sacco is talking about his work life at Mercedes-Benz where he worked from 1975 until 1999 (, 02. February 2015).

Bruno Sacco - mail from the master himself

In the past years I met people who presented with proud their W126-classics with an original signature of Bruno Sacco in the engine compartment. For those who don't know him: Sacco, born 12. November 1933,  is an Italian automobile designer who served as the head of styling at German car giant Daimler-Benz between 1975 and 1999. He is acknowledged as one of the greatest designers in automotive history (, 02. February 2015). The following picture was taken in May 2012 during a s-class-meeting in Bremen/Germany and you can see Sacco's signature on the frame.

Everybody was like "Wow!" and we envied the owner. Well, one day in 2014 (my W126 was sold and I got a good W201), it came to me that although Bruno Sacco doesn't work anymore, he probably would answer me if I would write him a letter. I did so in June 2014.

I tried to find out his address in Böblingen/Germany and I found a Mr. Sacco who worked there under the company name "Sacco Design Consultant Bruno". I wrote him a letter and tried to explain him, how much I admire his work, just like a teenage fan, o.k., with a bit more objectivity. It took him a while and I had already forgotten my letter. But he signed my printed data sheet of my W201 and sent it back to me with the words "With best regards, Bruno Sacco, 22. July 2014" Wow, thanks a lot, Bruno Sacco! The document has found its place in a nice frame and is hanging in my hobby room.

Exchange of the thermostat switch (100°C-switch) - W201

Some of you might have experienced difficulties with the M102.910, the engine of the W201, 190 E, 1.8, concerning high temperature. Imagine the situation: you are waiting in a congestion, there is only stop and go traffic, it is summer and the engine gets hot. Usually the cooling system of the engine can face those situations if every component of the system works fine. Normally, the temperature rises slowly from something above 80°C to 100°C. As soon as the temperature has reached the 100°C mark, the cooling ventilator should start working faster. Stepping on the gas a bit should lead to a sound of a high-ventilating ventilator. The ventilator gets his "command" from a temperature sensor in the engine. The problem is that sometimes this sensor doesn't work anymore and the ventilator doesn't start working as it is supposed to do. The following movie shows you how it should work. It is another self made video that I made last year.

2014-02-21 Tausch des Thermoschalters oder 100-Grad-Schalters, CLICK HERE TO WATCH THE VIDEO

You see that at about 100°C the ventilator starts running accordingly to the engine speed (rpm). As soon as a normal temperature is reached again the ventilator is disengaged. All this is done by a very simple thermostat switch, or 100°C-switch.

It's very easy to get to the switch. I unplugged the ignition cables from the distributor to get some space. Unplug the cable of the thermostat switch. Release the pressure by opening the cooling water reservoir. Unscrew the thermostat switch with an end wrench and replace it by a new one. Do the same work in reverse order.

This is the old thermostat switch. The new for my engine has the OEM 006 545 9124. I bought a switch from Metzger (thread length M 14x1,5) for only 12 Euros. Now, my engine is cooling down again how it is supposed to do. This is definetely worth the work time.

W126 promotion video I

In the 80's and 90's Mercedes-Benz produced lots of promotion videos. Those describing the souvereignty of the s-class and others describing the innovative safety features of Mercedes-Benz. But also fans of the W126 tried to express their thoughts and fascination concerning the W126, and they started to produce promotion videos themselves. One of these is the following one. This fan took scenes from a movie that was about the attack on the German banker Herrhausen.

The following picture is a real one. It shows that the assassins were "successfull". Mr. Herrhausen didn't survive this attack, despite the fact that the W126 was armoured.

Fuel consumption of the W201,190 E, 1.8

Talking about gasoline prices is one thing. Checking the fuel consumption of our car is another. My previous W126, 300 SE was sometimes very volatile. There were bad times, especially during the winter with frost and snow, when it liked to take up to 20 liters per 100km, sometimes even more when I only drove short distances. On the motorway during the summer it took only 9 liters per 100km. The average mix consumption was about 10-11 liters.

Now that I own a W201 the consumption has reduced of course. The engine is more than one liter smaller, it has less horsepower and is a bit lighter. But the consumption is not that much less. The average mix consumption is around 9,6 liters but I have to admit that the distances are not very long. Almost every day I drive 11km in one direction and 11km back in the afternoon. On the motorway you can see consumptions of around 7,5 to 8 liters.

So, yes, the W201 with the M102-engine is a bit less thirsty than its big brother, the W126 with the M103-engine.

by Alvimann,

It's nice to compare a bit and to check the fuel consumption, but for me it's just an indicator for the well-being of the engine. Extreme and permanent curve peaks are often an indication for a malfunction and should get further attention.

Gasoline prices in Germany

Today, I'd like to talk a bit about the gasoline prices in Germany. Since the surplus on the oil market the prices have fallen significantly. Since I own cars (and this is from 2010 onwards) I've liked to write down every fueling process at the fuel station (date, location, price per liter, liters in total). Over the years I've got quite interesting data.

In the following data sheet you can see the price per liter in Euros (left axis and the time axis at the bottom). For this car (a W201) I started the data collection in January 2014 when I bought the W201. You can realize that in October 2014 the prize for one liter (1 = 3,785411784 liter) gasoline began to fall. In October it was still something about 1,50 Euro per liter (= 5,68 Euros/6,41 USD for one gallon).

Now the prices haven fallen to 1,20 Euro per liter (1,35 USD) or 5,12 USD for one gallon. Still quite a lot of money, isn't it. In comparison to the U.S.A. we can find out that one gallon of gasoline costs only 2,044 USD. So in Germany actually we are still paying 2,5 times more than in the U.S.A. Wow, that's a lot, isn't it (data taken from, 01. February 2015).

Driving the star - a W126 video

Weekend, at it's time to relax and to enjoy driving the star!In the past five years I've made so many short videos and I've collected so many good ones from others that I'd like to let you participate. Click on the video below to enjoy a ride in my W126. The video was made in Bremen and is a little tour from the shopping mall "Waterfront" to my previous garage. At the minute 8:45 you'll see another W126 that I "met" by chance.

I apologize for the bad sound. The movie was made with a normal digital camera that I jammed between the dashboard and the windscreen. HERE YOU GO!

More snow in Germany

Yesterday we had more snow in North Germany. And we are expecting even more the next days. Funny to drive the W201 and its rear-wheel drive.

Error of the oil pressure sensor, part 2

Well, the error is quite typical for these engines. Let's forgive them. They are sometimes older than 30 years and still many of them are just running fine.

The sensor itself is located next to the oil filter. It's this grey-white rounded thing just below the base of the oil filter. The oil filter of the M103-engine (and also the M102) is located on the driver's side just in front of the fire screen and behind the air filter box.

I combined the exchange of the oil pressure sensor with an oil change. Because it's easier to get to the sensor when the oil filter is unplugged. To unscrew the sensor the only thing you need is an end wrench. To protect the environment use some towels. There won't come much oil out of the sensor base.

That's the old sensor that was supposed to be malfunctioning. Well, the new sensor was there and at this point I didn't know that I wouldn't succeed.

This is the new sensor. To fix it to the base you also should take a new seal. For the M103-engine it's the OEM number N007603012113. On the picture above you can see the connector for the cable.

On this picture you see the other side of the sensor. On the top you can see a little hole. In this area the pressure is measured.

Here you can see the exchanged oil pressure sensor and the exchanged oil filter above. It's a very easy  DIY-task. If you have further advices please leave a comment here.

Error of the oil pressure sensor, part 1

In May 2013 I noticed that my W126 showed an oil pressure in the display as soon as I switched on the ignition (motor not started). The oil pressure was something about 0,5 bar. Strange, it was supposed to show no pressure as the engine was not running yet. Watch the video and you understand what I'm talking about. I learned that this is a not unusal error, often shown by these youngtimers.

Here you can SEE THE VIDEO with a description of the error. In the video I tried different things: pulling off the plug of the oil pressure sensor, holding the contact of the plug to the mass of the car to see if the display shows a different value. Yes, it did. As soon as I was holding the plug of the oil pressure sensor to the mass of the car, the value dropped to zero. An indication that the oil pressure sensor was malfunctioning. Tomorrow I will show you the exchange of the oil pressure sensor.

Working creatively - build a W126 yourself

This is a funny thing that I found in the internet. If I violate copyrights here, please leave me a note and I'll delete it immediately. It's a W126 that you can build by cutting the paper and glueing the edges.

Click to see the patterns. You have an advantage if you own a color printer.

The outcome is... well, how to describe it nicely? Yeah, it has some similarities with the real one and in the end, it's just fun!

If you like, feel free and try it yourself. Would be glad to see the results here in my blog.

Heater core problems - a write-off?

In December 2014 my W201 experienced a very bad issue and reading in German W201-forums I found out that my problem seems to be a typical W201-problem. One day I saw some blue water dripping along the carpet at the center tunnel/driver's side footwell. Obviously it came from the casing of the steering wheel. I unscrewed the panel and saw the problem.

Cooling water came from somewhere behind the silver heating pipe (the heater core; is it called so in English?). Well, I was quite shocked when I found out that for the exchange of the heater core I had to get out the whole dashboard. I like working on my car but as I don't have the space to work without hurry and as I'm dependent on the car I was almost about to give up.

At the last moment I found a repair shop which was willing to exchange the heater core for "cheap money" (350,00 Euro, Mercedes wanted something like 900,00 Euro). To be honest there were other first signs like the fogged windows e.g. Fortunately I found out about this problem quite early I guess. The foot-carpet and below the carpet everything seemed to be dry but still it was a shock.
The mechanic did his job very good and eversthing is o.k. now. There's no loss of cooling water in the reservoir or anywhere else.

I have to admit that this is not DIY. But for this work you need a good experienced hand or at least someone who has done this before. You need some space and time. Many people in the forums said that the work is not so difficult. It's just a lot of work-time. May be, but I wouldn't recommend it to you doing it yourself when you don't have adequate ressources to do this job. Look how the old heater core looked like.

Happy that I could keep my old Baby-Benz!

Snow in Germany

Wow, today the first real snow this winter. About 3-4cm. Finally. A good day to check the ABS-system and to take nice snowy and dreamy pictures! ;)
