limp mode again, fueling issues?
Car goes into limp mode and loses power whenever I go WOT. I had the codes read and I am throwing a 29DC code. He rode with me while I was driving and the low pressure hPa was dropping into the 3000 range when I went WOT. At idle it was in the 5,000s and the high pressure pump was always 50,000+. This means I need a new LPFP correct? Here is a picture of readings at idle...

Put in new LOW PRESSURE fuel pump and it is doing the same thing! I noticed the car runs better when it's cold. The first few minutes after putting in the new pump, I was actually able to hit WOT... but once the engine is warmer it goes back to running on three cylinders. Code I keep getting on generic scanner is P142e, once I got a p3090. Car has no issues starting or idling, idles at 600 perfect and starts nearly immediately.

5 bar at idle is normal not dropping to 3 bar while going WOT is low... Does the new pump also drop to 3bar? Do you have a stock LPFP or is it upgraded?
Maybe you have a kink in the line somewhere... |
