Mercedes Repair Questions? Ask a Mechanic for Answers ASAP
Hi - can you tell where the rattle is coming from? Does the gears shift ok? Does the engine surge or run rough at idle? Has the car been checked for fault codes yet?
Best regards, Paul
Feels like an engine movement. Gears OK; idleing speed can be a bit irratic sometimes - increases to about 1100 rpm. 12 month service in January this year. Are fault codes a garage thing?
Appreciate your help
Hi - fault codes would need to be checked with a diagnostic tool, I would recommend this first if the engine is erratic. A common problem with noise & vibration can be the V belt tensioner - if this is worn it can cause a chattering noise & juddering through the belt drive. A common problem with engine running problems can be with a split breather hose under the air filter housing - see the following pictures for location:
