C350 Coupe (W204)
C350 M276 rattling noise ( tensioniers already changed)
Hi Guys,
I own a C350 Coupe with the 306hp M276 engine, MY11 round about 90k km on (ca 60k miles? )
Shortly after buying I notice a rather loud rattling noise after a cold start or an real extreme rattling after the car has cooled down for round about 10-50min.
Also an other symptom is that the car does not really start well after a long stand still.
If I stop the motor and start it right again, there are no problems and no noise.
I already got the car to my dealer, who did the complete tensioners and check valves.
What should I say, I didn't change anything on above described behavior. In 4 weeks service has to be done and I want to have something on hand if my dealer wants to convince me that this behavior is normal.
Had any one of you the same problem?
I also tried to record the noise I am talking about:
Appreciate your help!
