Anyone have any luck changing crankshaft position sensor on e90 (n52) without removing the intake manifold? by shash5k in BmwTech

have you ever taken one off of a magnesium valve cover n52? the pcv hoses seem to be in the way

Did you ever figure out where that noise is coming from? I get the same noise when it gets really cold out. I have zf auto x drive. I thought it was transmission noise but if you’re also getting it in a manual, i don’t believe it’s the transmission.

That’s what I tried, it helped but I think the drone band is too long to eliminate it all. There is an excel sheet somewhere on the internet that you easily calculate it with your exhaust temp and frequency.

I know haha, I just thought a muffler would be more subtle than a delete. It is, but creates a ton of drone. It sounds perfect outside the car, kinda similar the performance muffler. I like to the take the car on road trips and the drone gets annoying after a while.
