Hey, been having problems since before Christmas with the car. After getting it running all was good then the engine management light came on.
Next door works a garage and borrowed the remote computer to plug in an diagnose the problem which is P1128 fuel pressure regulator.
The reading for fuel pressure was about 290 bar - can't rememeber if that was the exact number but he said that it was ok.
The fuel pressure regulation was at 16%?
His garage does not deal with Diesel motors and he's only been there a couple of weeks.
If errors are cleared the car runs absolutely fine but a day later the engine mgt light is back on and the car is back in safe mode - won't go above 2200 revs.
Any help very appreciated. Thank you
if your garage doesnt know, best bet, im going to go with, is taking it to someone who does?
Pug dealer perhaps?
or at least a french car specialist.
the pressure HDis run their fuel at is truly terrifying imo, you wouldnt want to fiddle with it yourself unless you were confident in what you were doing.
4000 psi ish iirc
miss my 206 :,( the car of kings.
Should be about 300bar at idle, rising to I think about 800bar under full load for the older engines/emmision levels.
If it's throwing a pressure regulator fault, then I'd be looking for signs of metal bits floating around the fuel filter housing. If there is metal, then the high pressure pump is starting to break up.
You can try removing/cleaning/replacing the pressure regulator, but going by experience, it's only a temporary fix.
