It's near the turbo.

Shamefully taken from Audi Sport forum.

 

Thanks, think I can work out where that is. I'm hoping to maybe just get a second hand one to be honest as they are so much cheaper! Hoping to fit myself too. Any special tools do any of you guys know?

 

No special tool's needed just alot of patience.
I fitted a new one to my 225 when I changed the downpipe.
Iirc it was a 17mm I used & it's in the center of the turbo.

Check it's not been disconnected first, then clean up the connections as that's usually the problem.

Mine was running badly and extremely hesitant under load with a big loss in mpg. Vag com pointed to the egt sensor as it had come loose. Reconnected it and car back to normal now.

 

I have a egt sensor for sale if your interested?

 

Thanks guys. So to check its connections do you mean the ones to the battery? The unit was all plugged in fine but I didn't trace the rats neat of wires back to I'm guessing the battery?

I may be interested in buying one but ideally I wanted to just check mine was nothing simple first!

 

the EGT unit is located under the inlet manifold along with the connector and plug. As has been said worth checking mine I found mine disconnected with the same issues you mentioned..

Some useful picks on this from 'Horseoutside' on the post page at the moment 'Failing Exhaust Gas Sensor.

The sensor is not located under the inlet. However the connectors are.

Just checked it all out. The unit is under the inlet for sure as I just got it out of there. I think you are possibly confusing it with the lambda sensor as looking at the pic from earlier I think on second thoughts that may also be a lambda sensor not the egt?

Upon checking it the front connection looks good and the silver wire feels a little softer as its bent round a little but seems ok and I don't think it's possible to "fix" the connection there anyway. Is it most likely I need a new sensor?

Ps I felt the big 17mm sensor also so thanks for the help on that. Don't think it's going to be too hard a job.....

 

Sorry just realised you meant connections and probably meant the box to. I'm assuming when he said its under the inlet manifold he meant this box part

 

Yes the pic earlier in the thread is a lambda sensor. Egt sensor has a right angle bend just after the securin bolt and is on a braided silver wire.

Ok that's great, I could feel the bend etc so I have located it. Is it a bugger to undo as its been subjected to so much heat? I remember my lambda sensor on my old car was a nightmare to undo!

 

Did swapping the EGT sensor fix your problem OP?
