Mercedes ML Diesel Engine Problems

I also have a Mercedes ML I had similar symptoms a while back reduced power, rough running, and the check engine light For me, it was a bad injector The fuel mixture was off, and the engine wasn't running smoothly Have you checked for any obvious leaks or damage to the fuel lines

Thanks for sharing your experience When you say 'bad injector,' did you see specific error codes pointing to a cylinder, or was it a general mixture issue Did you consider cleaning the injectors before replacing them, or was replacement the only option How difficult was the replacement process

I can't recall the exact error codes but it pointed to a mixture issue I didn't attempt cleaning because my mechanic advised replacement was the more reliable and long-term solution I took it to a workshop I'd recommend getting it professionally diagnosed and repaired It cost me around 515€ including parts and labor

Thanks a lot for the advice I appreciate you sharing your experience and providing that cost estimate I'll probably take it to a trusted mechanic for a proper diagnosis and potential injector replacement Seems like the safest route, considering the complexities of the fuel injection system I was hoping it was something simple
