Random CEL under heavy acceleration

Random CEL under heavy acceleration
2006 A4 Quattro 2.0T
Only happens when heavy accelerating. 2nd gear or higher, taking the RPMS to 3500 or higher. The car suddenly stops accelerating like a rev/speed limiter for that particalar gear is set on the car. Once I upshift, it will take a second or two and then it will start to gain speed.
Best example I can give is in 4th gear it likes to do it at 45-50 so I shift to 5th and in 5th gear it likes to do it at 65mph so I go into 6th and it will climb to 95 but then no more.
CEL light comes on usually in 3rd gear when accelerating.
Alright, so when it happened the first time I took it to a buddy's shop who specializes in Audi, Mercedes, & VW. They checked the code and it said I had a bad electonic throttle body.
We did the test and sure enough the computer showed that when the peddle was pushed to the floor the car was saying that we only had it depressed 45%.
Replaced it with a brand new part and now 6 months later, under the same driving conditions that caused it the first time....CEL is coming on and then after a half a day or full day it will automatically just go away.
I have read on the forums that this part is notorious for failing right after the warrenty ends, but to do it right after I put a new part in!??
Car just hit 65700 miles
Thanks for any help

If it is your cam follower, I just recevied a service extenstion on my 2007 2.0 that specifically covers that, the Intake camshaft, and High Pressure Fuel Pump. Don't know if they'll cover the 2006, but it may be worth asking the question to the Audi dealer.

Thanks for all the responses. I will get it checked out to see what the code is.
Also, I did also just recieve that notice in the mail about extending the warranty from AUDI so hopefully that is what it is and it will be covered!!!!

Yea, I never have changed a throttle body on a B7 for any reason.... So commonly failed part... I doubt it.
Those are symptoms of the whole HPFP issue. But posting a concern about a CEL without posting what the fault is.... All your going to get is guesses.

It's the craziest thing, since it doesn't do it all the time. I have literally been trying to get it to come on getting on the highway for the last week and nothing.
