Good Afternoon Everyone! Looking for a bit of help on the below!

Had a limp mode issue with P0088 Fuel Rail Pressure too high. Coupled with a lot of limp mode and EML

After a bit of research I have replaced the N274 Fuel pressure regulator (Part Number - Bosch 057 130 764H).

I am trying to find to complete the adaptation/reset however met with Error Group 117 not available.

I have tried entering both security codes, but to no avail.

Any ideas let me know please. Thank you in advance. See full log below.

CBAB CR Engine



Many Thanks,

Ed

I would need to check on our CBAB but I don’t remember there being an adaptation in the list. Also, I would be more inclined to suspect the sensor, revised number 03L 906 054 A.

sorry I have also replaced the pressure sensor on the manifold as well. Car won’t run at all, wonder if there’s some air preventing the fuel coming through. I did crack the fuel lines to the injectors to try and get any air out but have run out of battery. Currently recharging.

You have bled the low pressure system in basic settings EVERY time you have opened the system?

Have you tried a sniff of gas down the ventilation hose fitting?

Hi all! Apologies for delay!

A bit of easy start got it going. I drove the car for about 45 mins before the p0088 problem reappeared.

I have now changed the fuel filter as precaution and checked the outlet regulator valve on the high pressure fuel pump looking for debris, but it was all clear!

Any help would be appreciated!
