Hi all,
My first topic so apologies if it is in the wrong place, i have a fault on my 2001 ibiza cupra and i cant work it out. Ive recently changed the fuel pressure regulator to one off an early vr6 corrado in a small attempt to rich my mixture up as its running lean at the top. After changing this i cleared all dtc's so the adaption values for fuel trim would start fresh.
Now a problem has arisen that i used to have but seemed to resolve itself over a long period of time. I keep getting the following:
17693 charge pressure maximum limit exceeded
P1555-35-00
16795 Secondary air injection system:incorrect flow detected.
P0411-35-00
This one doesnt bother me because i removed the secondary air system.
17536 Fuel trim bank 1 (mult) system too lean
P1128-35-10. Intermittent
Still running lean but was a problem previously
I dont understand the overboost problem, it will run about 11psi whereas previously it was happy with 15-16psi?
I dont understand how limp mode is controlling my boost down to 4 psi, because i have removed the n112 & n249 solenoids, i have also removed all plumbing from the n75 and am using a greddy profec 2 boost controller?
Is there anything in vcds adaption that i can change to alter the boost limit?
Why did my ecu previously become happy with 15-16psi after a few weeks when now it wont accept anything over 11?
I also have a problem with my oil light flashing and beeping but i have cleaned pump pickup, replaced pump, replaced oil and filter, and replaced oil pressure switch?
And my final problem is my rev meter, it jumps about but most of the time bounces between 0-500 revs and frequently sits on 0. Vcds records the correct revs and since my ignition timing is ok then i dont think its a sensor issue, also if i use vcds to run basic tests it moves the rev needle nice and smoothly and stops precisely at full deflection, zero and holds fine in the centre so vcds doesnt indicate its the clock either?
