Lambda sensor location/help

[Martyn85]

Hi guys, wondering if anyone could help me. Got my eml light on I've scanned with vcds and its brought up this fault (see attached) I've reset the code it will stay off for around two weeks then come back on. Is it just a simple job as a sensor change if so where would the location be please? A3 2.0tdi

the lambda sensor on the Audi 2.0TDI is located up underneath the exhaust manifold. You have to jack the jack up and place it on axle stands, then follow the exhaust up into and under the engine bay (won't need to remove the engine tray) and you will see it on the drivers' side but its a bit of a long reach, and its best you use the proper socket for the job which has a split along it's length so the cable can fit through. good luk
