Hey folks,
I usually don't bother people but I'm trying to find solutions myself and this time I need your help...
Last week my 535 went into limb mode during cruising on the highway and the journey begins or maybe I should say nightmare.
Next morning I couldn't start the engine, when I finally did it jerks as hell and went into limp mode right away.
I got a bunch of codes fuel related and everything pointed to failing hpfp so I just ordered a brand new Magneti Marelli from ECS, installed it and everything was kind of ok for 2 days.
I can't even get a log because it cut me off at 3K rpms...
What I've realized cruising around and looking at the live data that when I accelerate the pressure goes over 2k psi then goes into limb and drops pressure to less than 100 psi wth is going on?
Here is a log when I tried to do a pull but I couldn't:
Here is 2 minutes after that when reset the limb mode and was just cruising around with some small engine load{
Here are current codes:
DME active codes - 29DC - DME: Cylinder injection cutout.
29E0 - DME: Mixture control.
29E1 - DME: Mixture control 2.
29F2 - DME: Fuel high-pressure system, fuel pressure.
2B2C - Fuel high pressure, plausibility, cold start.
30FF - DME: Turbocharger, charge-air pressure too low.
- DME shadow (inactive) codes - 2FCA Fuel high pressure bei Freigabe der Einspritzung
2FDA Fuel high pressure bei oder nach Freigabe der Einspritzung (2.
Umweltbedingungssatz nach Zeitverzögerung)
2FDB Fuel high pressure nach Freigabe der Einspritzung
Codes from yesterday:
1/26/2024 7:46:00 PM
- DME active codes - 29DC - DME: Cylinder injection cutout.
29E0 - DME: Mixture control.
29E1 - DME: Mixture control 2.

I would highly appreciate if someone could take a look and point me some direction, can a bad injector cause all that mess? I've replaced these a few years ago for the index 12.
Thanks in advance,
Mark
