a4 08 Facelift 2.0tdi - Emission Control Sys light - Lambda?
Discussion
hi
My audi a4 2.0 tdi 140 08 >is driving fine to my knowledge but the ECS light has popped up on dash.
Mechanic said could be DPF, but have driven the car as told - no difference.
Got diags ran on car - it's saying the Lambda/oxgen sensor/is malfunctioning.
Mechanic cleared ecu reset codes everything, light dissapeared now re-appeared.
So got to get a Lamda sensor from somewhere (presumably) - are euro car parts or GSF parts ok to use in this instance or suggest Audi main dealer only?
Thanks in advance.
Mike

2 fault codes tonight
1st one oxygen lamda sensor b1 s1: signal too high (rich) P2199 or P2196 (took a quick pic)
2nd bank 1 cmp sensor (g40) engine speed sensor incorrect correlation p0016
mechanic thinks lambda sensor for problem 1 and camshaft sensor on next one.
Euro car parts for lambda sensor and camshaft sensor ??
Thoughts?

Hi guys
P2196:
in my occasion it turned out to be the heated oxygen sensor itself....I did a lot of research online and came to the conclusion it had to be it since I had no other engine running issues. After trying a LOT with my VCDS I paid the dealer for a check up. The chief enginner there said that it is a fault code that almost 9/10 times has to do with the sensor itself. His diagnostic VAS program suggested other options which I only had a glimpse of, but his words were that if it was a problem with the injectors or a leak anywhere in the intake or turbo or EGR there would be more DTCs and certainly impaired engine function. He checked my gars emissions to be 100% sure and quoted me 300 euro for changing the pre cat sensor. SOO....if you dont have any power issues and your exhaust gases are within normal limits then its the oxygen sensor. It has a lifespan of 160000km. It cannot be "cleaned" unfortunately. Got mine from daparto.de and changed it myself for 100 euro and no more CEL or dtcs!!!!....the sound of the engine seems smoother too and i noticed a 5% better fuel economy.
