Hi!

My M7 2006 will "back fire" (only one bang then runs fine) when i stop the engine and pull to start again.I am worry that this is causing damage to the engine?

Í am not sure but i think it's most common when i have driven low rpm:s (with my kids).
Can it be petrol in the pipe thats detonating?

Anybody else have this problem?


Best regards
Jörgen

before you hit the kill switch do you let the sleds rpms drop down to around where it idles at, cuz if you dont if usually will back fire when you start it

Check your throttle cable freeplay, between lever and the throttle block. should tell you in your owners manual how much gap you should have. Had the same problem on my 04 mc.
