LampyB, your right the car did just need a cam chain tensioner in the end. But just puttingone in would have been an expensiveguess. It could have been a low oil pressure problem also. So before dropping a grand on parts and labor I wanted to make sure I had the problem figured out. Most customers don't like for me to guess at what will fix their cars. You also have to understand that I had not seen this problem before on anAudi. So you have to kind of use Audi's diagnostic tree to guide you. If you read Audi's take on this they do everything but replace the cam chain tensioner. So that is why forums like this help so much. You can talk to a lot of Audi owners that may had the same problem.

RE: CAM CHAIN TENSIONER TESTING
only thing I can think of is if the cam chain was weak/stretched it would throw the timing out and that would leave a fault code but the pickup pipe is known to have this problem for getting blocked and im surprised it isn't a recall issue

IF i remember the manual correctly the manual says the oil pressure should be at LEAST 1.0 bar of pressure, that doesn't mean if your right over 1.0 bar that its good. Generally 1.8T engines have 3-4 bar at idle when the oil pick up tube isn't clogged.
Look, i'll make it really simple for you, you have two choices.
A) Replace the cam chain tensioner and hope it fixes it, and could be a costly mistake.
B) Repace the oil pick up tube ONLY, and if it doesn't fix it you just performed very good perventative maintance on the 1.8T engine.
To me its kind of a no brainer.

RE: CAM CHAIN TENSIONER TESTING
You won't even have to check the pressure probably, the tensioner should quiet up within 10 miles of driving. But yes you should see at the very minimum 2 bar at idle when the engine is cold IMHO.

Read my post "facts about oil sludge"
All 1.8T engines are covered under warranty regardless of mileage for sludge repairs as long as you can show proof of oil change receipts.
If there is enough damage to the engine they will replace the engine for free, even if it has 250,000 miles on it.

RE: CAM CHAIN TENSIONER TESTING
Oh BTW i recommend running some seafoam through the crankcase for about 50 miles before dropping the pan, that should ensure you get all kinds of crap out of your oil and PCV system. [8D]
