1242 / 0036 issue
im having this: 1242 - pressure sensor, intake manifold befpre compressor-input too low with trailing throttle
0036 - heated oxygen sensor, heating circuit (bank 1, after cat.)-malfunction
All started after i replace the charger oil and actuator spring in my r53. It was running well before this check light pops up. When the light pops up, the engine has a big vibration. Even after i clear the error, the vibration is still there. The mech check for any leaking with a leaking detector and there was no leak detected beside the engine oil cap. Is there any other thing i should check before replacing the sensor with a new module?
