Hi guys. Ive been searching the forums for a couple of days now to see if anybody experienced the same thing before, but I have not managed to find the exact same problem described in here, so I'm hoping someone in here is able to help me out.

Lately something strange happened to my car a few (3) times. It always happened shortly (~10 min) after starting up the car and driving gently for a few miles before the engine was completely warmed up.

What I experinced was that there just wasn't any power above ~2200 rpm in any gear. I then pulled over and stopped the car. After stopping the engine, I heard what sounded like either an electric pump/engine/fan running for 10-15 seconds and then it stopped. After this I could start up the car again and everything was running perfectly. On no occasion during these "events" did I get any limp mode or other indication af anything being wrong.

Now I would like to add that the car is otherwise running extremely well, I have just been a trip to Germany and have driven very fast on both the Autobahn and on the Nurburgring (a total of 4600 km), and at no time did I get a limp mode.

However I did get a "half engine light" on 2 other occasions, both when slowly deccelerating (leaving the freeway), but with no reduction in power. These may have come from my catless DP's since I also have the 29F4 and 29F5 codes. I have adjusted the DP fix once as I got the 29F4 and 29F5 codes relatively quickly with the default settings.

I was thinking it could either be the HPFP or maybe the vanos solenoids from what I have read on this forum, however I have NEVER had a single long crank, and I have close to 80.000 km (50k miles) on the car now, with a tune for 32.000 km (20k miles).

My question is if any of you have a clue what/where the problem is. I just scanned the codes this morning, and I have the following: 2AAF, 29DC, 2EE3, 2D5A, 29F4, 29F5

My guess is that the 2EE3 possibly came during my laps at "the ring", although I never got any limp modes or experinenced any drop in power while "racing"

Any feedback/advice will be greatly appreciated, as I would like to have the issue solved and neither me nor my mechanic know excatly what is wrong.

Thanks that's also what I thought was the most likely cause, I just didn't want to change a lot of stuff without reason. I'm all out of warranty anyway.

On a side note, I can't believe I didn't find that thread while searching....

I know i am necroing this thread but, did replacing the HPFP clear the 2D5A Control motor torque limitation code for you? That is the only one I am getting right now. Thx.

Yes, a new HPFP totally solved it.
