Error Code P0546 - Exhaust Gas Temperature Sensor Circuit High

[RICHD10]

Hi all,

I have recently purchase a 2003 Audi A2 1.6 FSI Sport which had only done 30000 miles which i thought was good for the year. When I drive around town (short distances) its fine i have no problems other than this knocking when pulling off, of which I have established the problem. However when i travel with work on long distance i.e. over 100 miles i get the engine management light which keeps returning the following code:

P0546 - Exhaust Gas Temperature Sensor Circuit High

Does anyone know if this is a common issue and how i can fix this problem?

Someone suggested a 'lamperprobe' but again unsure what that means exactly?

Keep us posted

Exhaust gas temp sensor is not a lambda sensor, it does what it says on the tin!

OK thanks , I'm off now to elucidate!

Ye its def not a lambda probe, the dealership told me it was even tho the following error was showing:

17861 - Exhaust Gas Temp Sensor 1 (G235): Open or Short to Plus
P1453 - 35-00 - -

I changed the lambda probe and it didnt solve the problem on my S3, so now they said its a temperature gauge (part number - 06A919529 and its been 8 weeks and I'm still waiting, apparently audi in germany are taking the p!ss. Just hope they got it right this time.
