Hi.

Thanks for the info. However, I am still having issues with this car.

The garage replaced the pressure sensor after no pressure difference was seeking live readings. but it was still the same.

When I tested the supply voltage to the sensor there was 0v. Continuity to ECU is OK on all 3 wires. I rechecked the ECU lives and earths and they were all OK .

I now suspected the ECU, a replacement was sourced but when fitted we still get the same codes plus 1 additional code 40 unknown.

Any help would be great before my ever greying hair is torn out!
