Im guessing i can move them one position and see if error code changes ? There seems to be a 4 volt and 11volt ngk optio ..anyone got a link or part number Adrian

Thanks for your help Steve. Are all 4 identical and is it usual to replace all 4 ? Would a 2 and 3 swop help identify if its glow plug or missing voltage ? Im worried a broken wire scenario would give same error , is the supply wire possible to test . Ill get error code again co66 or similiar from memory . Adrian

Daughter's A1 2011 tdi has a glowplug2 unexpected voltage error on start up , just need help figuring out what to buy/replace to resolve . i will scour the forums and appreciate the wealth of knowledge that your community knows and shares.. Thanks in advance - A
