I saw the link, very nice addition to the FAQ, I haven't seen that page before :thumbup:
I have info from PLAYED and I am almost done with teaching and grad school for the summer, so I think once August rolls around I will get to knocking out a revised FAQ. I think it is time, although its been given minor updates the bulk of it is from the original post almost 8 years ago (holy **** I've been here a long time). Time to account for the better knowledge base and wider/different used market, and I'd love to get second post space right under my initial post for links, diagrams, etc. Can you make it happen Mr. Moderator?
Wow......I've got some reading to do. I'm a decent shade tree mechanic but find the Audi a challenge. It works like all other automobiles with a different spin on things. For example I'm used to Chrysler turbo systems. My TT has a turbo but the way it handles excess boost is totally different than the Chryslers that I know.
I recently learned that a faulty EGTS can also cause an overly rich condition. You will also get the DTC 17861 (P1453):
Exhaust Gas Temp Sensor 1 (G235)
P1453 - 35-00 - Open or Short to Plus
This is an expensive part new and not so cheap used. The part number is 06A919529B (or some derivative). The sensor screws directly into the turbo housing on the 225's K04. I'm not sure it's used on the 180's K03.
It is accessible from the top once your remove the turbo charge pipe and even the strut reinforcement cross-member. I uses a 17mm spanner wrench. The controller/processor snakes around the driver side of the engine and mounts to the underside of the intake manifold. It can be a pain to remove the wire, etc., but certainly doable.
