Default Re: 2.7T engine problems

Has anyone had serious problems after the check engine light flashed multiple times ? Audi said that if it didnt just come on but it flashed first it means to stop the car instantly and get it towed in...serious or no... let me know

However, my favorite mechanic, an excellent local Audi expert and racer and Audi loyalist to the bone, insists that the 2.7T engine is REALLY bad news. In fact, he's convinced that Audi should recall them for updates. According to him, it seems that Audi dropped the ball on the 4-valve v-block design causing seals to break down after 60K miles. He's already rebuilt 12 of these engines over the past year, all with <100K miles.

So, I'm writing to this forum to find out:

1. Anybody had similar experience with the 2.7T engine?

2. Has there been any acknowledgement from the factory on the existence and/or cause of this?

3. Any after-market cures to look out for so that, once re-built, one could be confident that it was fixed.

4. Any indication that it's inherent in the design of the engine and can't be corrected.

Honestly, I've been a die-hard Audi fan for nearly 20 years. But this shakes my confidence in the company, especially in light of the fact that they seem to be totally sweeping this under the rug.

I drive a 2001 A6 2.7, 6-spd quattro. I bought it in 2014 with 183k on it and right now it has 262k on it. The clutch(original clutch I might add) just went out so it is in the shop for that, but other than fairly high maintenance costs, the 2.7 is an awesome engine with tons of power and options for chipping. BTW, I am 48 yrs old and I drive it like I stole it-most of the time.

What could be the problem - when car is cold its not boosting at all - like 0,2/0,3bar, when its warm 0,3/0,4, when its hot -0,5bar. Turbos should be ok. I have changed all oxygen sensors and one EGT sensor. There ar two fault codes related to n80 and leak detection pump and thats all. Could it be failing n75 or something?

Anyone? Byu the way, if I leave warm car for 20-60min and then drive, then it boosts 0,6/0,7bar for 2-5minutes, and then again its limited to 0,4/0,5bar..

This week I just took my 2003 A6 2.7T in for a code P0012.
I only have 81K miles on the car and baby it all the time, synthetic 0W-30 every 8K miles, religiously warm up for three (3) minutes before taking off and cool down for three (3) minutes before shutting down.
Diagnosis is new timing belt, new water pump, nad CAM adjustment. Family friend owns a German repair shop specializing in Audi and VW so we receive a very good deal on the work. Total cost with parts and labor was $2,580.00.
Love this car and since I live in Colorado and am able to take the train to work daily I do not put a ton of miles on her and have NEVER been stuck in the snow.
Cost of owning an Audi!
