I bought my daughter a 2012 C250 recently and it's giving me trouble so I'm here to found out more about the problem.

I'm not sure on how to use this site but here goes. When I first purchased the 2012 C250 it did great. All of a sudden I lost power. So I took it to a German mechanic. They pulled the code and told me I needed to see the dealer. The dealer said there a recall because of a program upgrade on the ECU. They reprogrammed the ECU and it worked for a day and the same thing happened again. This time they said it was a high pressure fuel pump. $1400-1500 down the drain. Has anyone else experienced this situation?

The 4-cylinder car in the 250 engine called M271, and the 6-cylinder engine in the 300/350 called M276, are direct-injection engines which have a high-pressure fuel pump in the engine compartment that is well known to fail now. It's a common problem with these engines and they were failing so badly and frequently that some dealerships did not have enough quantities to service all the troubled cars.

So yes it's a common problem on these engines and you must replace it. The dealership will definitely charge a lot so see if the German independent mechanic can do it for cheaper.
