I have a 2007 Audi a4 turbo. I'm 2nd owner and I have had only one issue until now. I took my car to pep boys for new tires and while I was there had them do anot oil change on it. I only have ever put in 5w40 full synthetic oil. As I drove home the car ran a lil ruff and as I pulled into my driveway the oil pressure too high light started flashing on the dash. Is there an easy way to determine if it's the oil pump or the pcv valve. I did notice there is some oil around the coils and I'm not sure if it's from the oil change or what to do as I don't want to drop a lot of money on the car. It's also had about a couple codes pop up. Engine misfire, bank too lean were the codes. I read on the forums that if you try and pull the oil cap off while it's running and it was really hard to get off it leans more toward the pcv valve. Anything else I can do to check this out or where to start without dropping 2k on a mechanic.

Oil pressure to high? Or oil level too high. I would bet those guys put too much oil in it. PCV is not going to cause high oil pressure. Yes they are bad if you cant remove the oil cap when its running. The oil pump relief valve could be stuck, but its really doubtful.
