Lambda sensors

[Audi_A31.8T]

Getting a few faults code for lambda sensors so though if just replace them
are they both the same or does any1 have part numbers I have a 2000 a3 1.8t aum engine code
also where is the connections located
thanks

soak them in vinegar see how you get on, it worked for me

What are the codes? don't assume a fault code for a sensor means it is faulty...

Yeah... fair point... these suggest both are not happy...

17608 - Boost Pressure Control Valve (N249)
P1200 - 35-00 - Mechanical Malfunction
This typically happens when you have done an N249 bypass or if not you have a faulty DV

Is the pre and post cat sensors the same or are they different?

 

[rustynlc]

Don't quote me but I'm pretty sure the post and pre work on different perameters, so are both different, I'm sure though someone can clarify!??

I'll take them both out and I'm sure I can take them to motor factors and get what I need cheers
