Hello everyone, I drove to work this morning and got a light up on the dash, so had a look in my Scangauge to see what code was stored for the fault,it showed P1421 secondary air injection valve circuit short to ground is this code anything to worry about? And Im guessing maybe it would be a good idea to get a blanking plug and resistor it so I dont experience any further problems with it? It will help tidy the engine bay up a bit too Any thoughts or input on this matter welcome, cheers. PS.Sorry mods its not in the VAG.COM area I thought it may be more relevant in this section, feel free to move thread if you disagree.
