Hi,
I have a 2007 A4 2.0 turbo fsi and the check engine and epc light is on. It is idling and takes time to catch speed when pressing the accelerator. I read online that it could be the crankshaft position sensor. I replaced it but it only fixed the issue for one day. I took it to another mechanic who said it is the camshaft and fuel pump and will cost over 3000 to fix. Do you think this is the problem? I would hate to pay that much and it not fix the issue.
please advice
