Hello guys, so I just swapped my e46's M54B25 for a B30. I've been getting a code in INPA (error code 18), which is a code for an exhaust cam sensor. I swapped it with the sensor from my B25 (same sensor), both of them were from BMW. I even checked them with the multimeter, they both work. I...

I put in a new cam sensor and car was searching for a shift and lost power. I unplugged it and it improved. Figure bad sensor so I replace with OEM sensor and same thing happened. Why would the car work better with it unplugged. Does the ECU have to be updated or is it plug and play, like i thought.

I was not getting a cam sensor code but symptoms seemed to be a cam sensor problem so for the heck of it I unplugged the sensor and the car runs better now. Can anyone explain this? Symptoms were low power, RPM's fluctuating, not shifting (automatic) when it should. Thanks

I have had intermittent starting problems that drove me crazy. When the engine was LUKE WARM it was not possible to start. That is: turn key, starting motor comes on, engine does not fire (or maybe fires once or twice and then dies). This typically happened after parking for 1-2 hours. Cold...

I am having issues with my intake camshaft positioning sensor which i assume is camshaft sensor A. A few months back my check engine light came on and it was the camshaft sensor. i had it replaced with an aftermarket sensor. 3 weeks after i replaced the sensor the check engine light appeared...
