I have a C180 Mercedes Benz 2002. (there wasnt an option for this on dropdown) I recently had to replace the Head Set, skim the engine, replace the breather house, chain tentionor and air filter and water pump. After that the check engine light kept on coming on and the engine was lacking power when it started and would idle rough and sometimes stall. We were then told that the crankshaft sensor which we did. The car still stalls and lacks power when starting - we have now been told that we must replace our airflow sensor. Is it probable that all these could have gone wrong at the same time? It seems to be an ongoing battle with which is bleeding our bank account dry. South Africa

Have you done this all at one garage? It sounds like they have no idea what the problem is and they are replacing parts. You may want to go elsewhere. Honestly, I've heard that these cars are notorious for ongoing and expensive problems. It may be time to get rid of this one, if you can.

I have a C240 with the same problem, often no power when starting out and slowly power comes back. particularly bad when its hot outside - just been told by friend it must be the seals on the injection system which have gone hard and the petrol will vaporise - so going to change them 12 x 45R for the seals - we will see - if you sorted your prob drop me aline on firstname.lastname@example.org with teh remedy
