Error Codes and general advice
Ok so my A3 that i bought on a limb has 4 error codes. It is a 1.6 1998. I looked in the section for help but it was not coming up.
So the codes are
00537 Oxygen Sensor Control
00557 (no code found in the manual)
00525 02 Sensor - Voltage Low - G39
00668 Battery Power Voltage Supply (terminal 3)
So does this mean i must replace the Lambda Sensor (i am guessing there is only one in the front downpipe)
It is idling a bit rough and is stalling VERY easily.
Any help or advice or help would be greatly appreciated. Remember i am a relative noob so idiot speak would be preferred! :salute:
