Title: Code 17840 -N112 interruption
Post by: alexd on 12 December 2010, 20:37

Hi all got my mate to scan my 1.8t yesterday and it flashed up with needing possibly a MAF, but also came up with this code


17840 secondary air injecting valve -N112 interruption


Now ive had a search but can't seem to find much info about fixing it, any one had this before?? Any info to point me in the right direction would be much appreciated  :tongue:

From what I've read the N112 valve is part of the secondary air system which helps to quickly warm up the catalytic converter from a cold start. Either the valve has failed or the connector is disconnected/corroded, try reseating it and/or contact cleaner
