Mercedes Repair Questions? Ask a Mechanic for Answers ASAP
Hello my name is ***** ***** I can help
I would like to know if you have tried anything yet
Ok, do you have any check engine lights on?
Ok, the first thing I would try is getting a can of brake cleaner and spraying around and at the EGR valve.
If the EGR valve is stuck open it at idle, will cause an imbalance of the air fuel mixture
Has any work been done on the car recently? Oil change etc?
Ok, also try spraying the brake cleaner at and around where intake gaskets are. If there is a change in the way the engine sounds then you have a leak. Same for the EGR valve
Don't think that would cause this problem. Yes, I will be checking my phone for your response
Leave the ticket open till I have answered your question
No problem, have a great evening!
Good morning, have you tried anything yet?
If the car was too hot you would notice it on the temperature gauge on the dash. If it was overheating then yes it can cause pre-detonation. Do you have the coupe or sedan model?
Do you have a coupe or sedan?
Automatic or standard?
This should be an accurate picture of the EGR valve
You have not responded to my reply, how are things going?
