Hi all,

I need to disable 2500rpm limit, which comes on the dash after some spirited driving. This limit comes with faults:

Oil Pressure Regulating Valve P164E - 001 - Electrical Malfunction
Oil Pressure Switch P164B - 001 - Malfunction - Intermittent

I've disabled those faults by changing fault class to 0. Those no longer show on ECU, but the limit still kicks in.

Any ideas how to get rid of it?

I think wiser is to rid out of failure, not deleting an engine safety margines, isn't it?

Different engine has been fitted to this car. It has no pressure regulator, meaning that the safety margins in question are redundant.

I can turn off the faults codes. But it is necessary to check whether the restriction will reappear.

I can test your solution on the car, no problem.

if the car is in limp mode which by the sound of it is, removing the dtc wont remove the limp mode.
