hi i have some problems with the rail pressure. I put him on 125bar, only sometimes he hang at 88 or 100. when I go to full load and the pressure before is about 100 bar then he goes to the setpoint only when I am under 100 bar he hangs often. is the problem known?
hello! i`m from Argentina, my audi s3 have the same problem and i change every part i can to save the problem but this not change.
Changed original and ttrs fuel pump, autotech and hpfp new, rail sensor, lpfp sensor, ecu, injectors, chain and tensor, variator vvt, crank and camshaft sensors. All new
Channel 91 & 94 in vagcom all perfect, (2 to -2 when hot engine).
If accelerate the car in movement with the rail charged in 100bar or more...the requested rail is 135bar and the actual rail follows perfect all. (not problem in this case)
If accelerate from 0-100 km/h with the rail charged in 50bar, the requested rail is 90, 80, 100 in diferrent tests but never go to 135bar, timing injection is more 10.0, lambda control go to +25 and the throttle close.
Try with original map and the problem is minor...but persist.
Any idea for help me to discover the origin of the problem? Thanks in advance
