I've got a A4 Quattro 1.8T thats is throwing some error codes.
The first code up was:
P1128 - Fuel trim: Bank 1 (mult) System too Lean
This light started coming on intermittently and got gradually more frequent. The car seemed a bit down on power but other than that was fine. I bought a OBD2 scanner and cleared the code and it stayed off for a couple of days but the light came back on today.
The scanner now shows 2 codes, the first one and a new one:
P0011 - Bank 1: Camshaft A (Intake) Retard Setpoint not Reached (Over-Advanced)
Now the car is struggling to idle, it is over-revving every few seconds. And the car seems very slow and sluggish. I haven't driven far but I also suspect my MPG is down.
After doing some research on the internet I've found possible faults are a faulty Camshaft Adjustment Valve 1 (N205) or a faulty Fuel Pump Relay (J17).
Anyone had any experience with these faults?
Thanks for any help in advance :D
