    2006 audi a4 2.0t quattro

    2 Error codes

    P0089 Fuel pressure Regulator 1 Performance

    P0304 Cylinder 4 misfire Detected


    So Im under the assumption that I need a new coil pack, and fuel pressure regulator, but I read online that the p0089 code can also do with the cam follower?

    Anyone else have these issues?

    Bought this car less than two weeks ago at 55K, put less than 500 miles on it sense. In the glovebox there was a service document that said the car had an issue with the previous owner, with the oil pressure light being on but the oil levels were fine they "duplicated customers concern. Performed Audi Procedure to fix customers concern. Performed flush on engine, removed oil pan assembly and cleaned pan. Replaced pick/up tube assembly and oil level sensor. Replaced oil sender assembly." This service was done less than 2k miles ago

    Not sure if that info in related or necessary but why not throw it in here.

    Does the car hesitate or it's driving fine?

    Hmm I have the same year I also just for the P0089 code today. It's a conspiracy! What's strange is my car is driving fine with no issues.
