Tl;Dr summary version at the bottom.
This blog post details my experience of buying a used W211 Mercedes Benz. The purpose of it is to hopefully allow others to avoid the mistakes that I made in the buying process.
Back in September 2014 I finally realised a long running dream to buy a Mercedes Benz. I was pretty stoked about it. The model was Avantgarde E270 2002 CDI (disel).
Before buying the car I searched for months for a suitable candidate and test drove about 5 other cars. I read a lot of guides but what I found most helpful in my pre-buy research was Mercedessource’s Buying a 10 to 15 Year Old Mercedes video series. The series covers a lot of good advice but if I were to pick one tip it’d be the how important it is to have the car inspected by a professional before committing to the purchase. This point was also raised in all the guides I read and as well by my friends.
Initial inspection by me revealed that the car had been very well taken care of by its prior owners, it looked incredibly good for being 12 years old. The car had been driven 137,000 KM (~85,000 miles). The service record showed that it had always been taken in for service at set times. The car had 3 previous owners, first owner had the car for about 6 years, second owner few months, and the third owner about 6 years. In the initial test drive the car drove incredibly well, very stable and shifting was tight. One thing had me worried though:
Before the test drive I asked the prior owner about this warning message and he said that he had the car inspected before listing it on sale and that the front brake pads needed replacement (more on that later). I was wary but confident that an independent inspection of the car would tell.
After the initial test drive I took the car to a full inspection at the indie Mercedes specialist Bíla-Doktorinn (e: The Car-Doctor). The shop came highly recommended by few friends for their extensive knowledge working with Mercedes Benz. Bíla-Doktorinn made a list of flaws and upcoming maintenance. Among the things mentioned was that the front brake pads and discs would need a replacement in the next few thousand kilometers. Aside from some other minor flaws the owner of Bíla-Doktorinn affirmed that the prior owner had taken very good care of it and had it serviced at his shop throughout the years so he was very familiar with it. This to me sounded very reassuring so I proceeded with the buy and booked an appointment at Bíla-Doktorinn to fix the brakes and other maintenance.
The shop had a fairly busy schedule so after about a week and a half they took the car in. While working on the car they found some other flaws with the car. For example they found that the water pump was loose. It wasn’t really reassuring to hear that after the car had been deeply inspected, but friends assured me it wasn’t such of a big deal. The water pumps tends to be in a very hard to access place and easy to miss. This was indeed the case, when replacing the time belt the mechanics noticed the loose pump, called me and got my confirmation to have it fixed as well, for which I am very thankful.
However after about a day after the service I noticed that the front breaks would consistently squeak when coming to a slow stop. I drove the car for about a week on the advice of friends, sometimes car breaks will stop squeaking after they have been worn in for a few days. Another thing bugged me, the warning message ”Service brake Visit workshop!” was still appearing. After about a week I contacted Bíla-Doktorinn about it and they took a second look and fixed the brake squeak issue at no cost.
When picking the car up I queried Bíla-Doktorinn if he was able to clear the warning message. Then I was told the true meaning of the error message. The SBC brake pump, essentially the brain of the braking system was due for a replacement. The cost, about 200,000 - 400,000 ISK (about $1500 - $3000).
Very shocked and a bit mad I asked:
Why did you not tell me about this when I had the car inspected by you?
Rúnar, the owner replied:
This happened after you bought the car.
A flat out lie as the message had been in the dashboard since I test drove the car and turns on as soon the car is switched on. From my point of view Rúnar took a gamble by denying responsibility hoping that I did not have a proof that the error message had indeed been in the car from the start. His gamble payed off as I had not taken a picture and error codes did not include mileage numbers until in later models.
After bitterly digesting this all and finding that I had no legal rights to a damage claim due to my lack of evidence, I find 3 things disturbing:
The error message ”Service brake Visit Workshop!” is displayed in the dashboard when the car is turned on. It’s an umbrella warning message indicating that something is either faulty or due for replacement in the braking system. It is not an indicator for expected wear on, for example brake pads or discs (then the warning message includes the word wear). This warning message alone should have tipped off an experienced Mercedes mechanic doing work on this type of car. It didn’t.
A simple code scan on the car will show this fault as well. Either Bíla-Doktorinn did not do such a scan or overlooked it. A major mistake since the reason why people take their car in for professional inspection is to find hidden faults like this.
Here is the kicker, the prior owner told me that before listing the car on sale he had it inspected by, you guessed it, Bíla-Doktorinn. If true, this means the car got inspected TWICE and this easy to find but major fault went unnoticed. I’d call that gross incompetence.
There is another possibility, that the owner of the shop and the prior owner were close friends and I was being misled as to the true state of the car. I however find that scenario unlikely.
Given everything, here are some of the things I’d consider before buying an used E class 2002-2007 W211 Mercedes Benz. Learned from my bitter experience:
