V50 - 1.6D sudden acceleration/idling at 1200RPM
-
Hello, has anybody experienced issues with idling on V50 1.6D D4164T (1.6HDi).
Almost every start car revs by itself, to around 1200rpm and shows message "engine performance reduced". However perfomance is not reduced, power from the engine is the same as before. But it keeps speeding by itself.. When I press clutch, ECU is holding revs to 1200rpm, and never drops to original 800-1000rpm.. It only drops for a while, when I turn off and on engine.. For some kilometers, same issue..
DPF was cleaned, Throttle body was replaced from good known vehicle, calibration was successful.. And the problem still persist.. EGR body (on diagnostic is however error code EGR control jammed, was was there before and never had a problem). EGR valve was replaced just for testing purposes, problem still persist.
Turbo valve was replaced, also small pressures sensor etc.. related to the turbo.
Throttle pedal was also replaced, at VIDA diagnostics shows 8% position - which is okay.
Sometimes car just randomly shuts down and back up when driving..
Only thing I´ve done months ago, i have applied custom tune (ST2 EGR+DPF OFF) from D5T5 for around 250€. Vehicle was working fine, last week when temperature raised the problem appeared. I can´t go back, because my diagnostics cable is broken and waiting for delivery of new one..
Does anyone know, what can it be ? Currently VIDA diagnostics shows nothing related to my issue.. Thanks
