Help needed Please Fault code P0546

--------------------------------------------------------------------------------

Hi all ,
I've just bought a 2lt FSI Gt for my Ruth and it's chucked up a fault code P0546 Looking into it the FSI does not seen to have a EGT sensor . But Bank one senor 1 is the first lamda so I have replaced it but no luck . Any ideas or help would be great ..

Thanks Paul.

I can take a look tomorrow Paul, I work for VAG

Common problem on FSI is the NOX sensor

P.S Battery kit arrived today

Well fitted a new lamda sensor . No good still the same ..

So looking into it I have found it has 5 YES 5 lamda sensors and a EGT sensor .. WTF .

Why the hell does it need 5 sensors in the exhaust ??

I unplugged the EGT sensor and took it for a drive and the light stayed off.

Take it to someone who knows what they are doing, dartboard diagnosis is a costly game paul;)

Did you sort the problem?

Cheers . Not yet .
Even VW can't say it is one sensor ! it could be one of the 5 lamda sensors ,or might be the EGT but it could be the NOX sensor ..

I have a mate with VAG com.. Going to look at live data .
