Camshaft sensor BMW e39

While I figured out what the problem was, I found people with similar problems, this post is for them.

The symptoms were as follows: injector squeal, blunt bottom, vibration at idle, consumption increased by 20%, rich mixture (pipe, lambda and catalyst do not stink).

ATTENTION! Symptoms are typical only for M50 2l engines with Siemens injection and M52 up to 98 onwards, possibly for later models, I can’t say others.

I connected INPA, pointed to the DPRV, looked at its data, it seems that it does not complain.

I removed the sensor, checked with an ohmmeter between 1 and 2 contacts should be 12,2 Ohm - 12,6 Ohm, between 2 and 3

0,39 ohm - 0,41 ohm. I had a gap between 1 and 2. I removed the wire braid, it turned out that the wires were dead. I tried to measure directly on the sensor, the same thing. Dismantled, measured the contacts and made sure that it was ready.

It changes very easily. The second time I changed it in 15 minutes, the first time I dug for 40 minutes.

You will need: a well-lit area, wrenches (32, 19, 10 open-ended), a 10-inch socket with a wrench, a thin flat-blade screwdriver, and grasping hands. It is better to do everything on a cold engine, your hands will be safer.
