Well i was tightening the lug nuts on my wheels today to see if they were the cuase of a knock i was hearing last night and a freind came over who hasnt seen my 7 yet. He asks if he can sit in the car, i told him sure just dont **** anything up. Well next thing i know hes revving the **** out of the engine. I run over to the drivers side and tell him to stop. After he let off the gas all i could smell was something burning coming from the exhuast. Anyone know what this is or have this problem? I hope he didnt mess anything up and he's the last person that touches my 7 besides me for now on.

 

maybe you caught a plastic bag or something, check it out

 

Nope nothing up under it.

 

Maybe its the cats?

 

Probably the cats



Your noise was probably the brake pads like I said, especially if it hasnt happen since.

 

this is a different noise it was when i turned. The other noise that i had a little while ago was the brake bads though.

 

maybe he revved and the cats fell apart

 

maybe its oil.

 

it could be.

 

my car does that occasionally. it will burn off a little oil right when i start it up. not too often though.
