hi,
my daughters 1999 Audi A3 1.8 failed the nct this morning for emissions failure which in fairness are very high ( see attached)
I ran Vag-com over a month ago and got a single
fault 16518 oxygen ( lambda sensor ) B1 S1 no activity
P0134 - 35 - 00 - -
I cleared this error and yesterday reran Vag-com without any errors showing up so I'am wondering where to start
if i have to change the lambda sensor where is it and how easy to change ?
thanks in advance
brendan
