Ok, so I took my car to the dealership, and all they could come up with was an intermintent MAF sensor problem and a rich fuel air mixture misfire. I changed out the MAF, and coil packs, but I am still getting the misfire. Any ideas out there?

 

It could be the PCV as I had similar problem but maybe some else could confirm as im no expert.

If it is its about £30 from Audi p/n 064 129 101 D

 

Thanks for the response. I will look into that. along with driving the car off a bridge At this point I will probably just start replacing everything.
