    Hope someone will see this. I’ve just done a chain and tensioner on a 2007 2.0 tfsi Audi A3. I followed the procedure here exacctly but when I start the car up now it gives me P0011 fault code, camshaft position. I reset the fault and drove 80 miles (brave I know) and didn’t have the fault reoccur until I went to start it up. Again reset and didn’t show until stopped and started again. If I retard the inlet cam by 1 tooth the fault clears but very slightly under powered at low revs. Could this be an issue with the vvt adjuster?.
