N62 4.4i Camshaft Pos Sensor DIY anyone?

Please let me know the outcome of your issue. I just did basically the same repair as you (upper timing covers and valve cover gaskets) and I am getting a Crankshaft Position Sensor (CPS) code as well. I'm really interested to see what the outcome is in your situation. I am getting a DME code for the drivers side intake CPS. I have cleared the codes, swapped the driver and passenger side intake CPS, and am still getting the driver's side intake CPS code.

I suspect that the CPS is not the issue in my case, but I ordered a new one anyway. When do you expect your new sensors?

I installed one new CPS on the drivers side and cleaned the other one but I'm still getting the exact same codes and very rough idling. The other CPS is coming in tomorrow. I suspect the issue is not the CPS but the vanos solenoids sticking or something. Could you please swap the passenger side vanos and see if the codes thrown move with them? Tonight I'm planning to remove the driver side solenoids and clean them thoroughly. I read in the E90 post a vanos cleaning DIY on their N54 engine and it does wonders. http://www.e90post.com/forums/showthread.php?t=486201&page=3

The E90 Bentley mentions that dirty or sticky vanos will throw CPS codes.

Here's the codes I'm getting from DIS and INPA:
1) 2A84: CDKENWS2: intake/inlet vanos 2.
Limit stop adaptations out of valid range
P0021 A camshaft position- timing over-advanced or system performance (bank2)
Possible causes:
-Vanos intake solenoid valve defective or soiled
-intake camshaft defective (vanos adjustment unit)

2) 2A89: CDKAMWS2: outlet/exhaust vanos 2: camshaft adjustment has not reached retard/late position: P0024 "B" camshaft -timing over-advanced or system performance (bank2)

ttt was this ever figured out? also if you look and compare bank 1 and bank 2, the electrical connections running from the intake manifold area to the CPS sensors on either bank seem to be switched for the sides? (i.e. the CPS sensor line on bank 1 closest to the front goes to the upper, and the line behind it goes to the lower. on bank 2, this seems to be reversed. weird!


Timing, VANOS, 1 tooth offset to crankshaft - Page 3

here the guy reversed the two cps's and was running rough, but this was resolved.

Anyone know where the VANOS solenoids are on the N62?

Sticking out of the front timing covers - about 3 and 9 o'clock.

I have had the exact same issue followed the same pattern. Mine was telling the bank two exhaust camshaft sensor. I was just about to buy one and decided to try to take it out. (I totally agree with nra0707 about holding on the 1/4" wrench tightly) I only noticed that the sensor on bank two had some dirt on it and I only changed the valve cover-timing cover of bank two. I cleaned the sensor and swapped it with bank 1. The problem is gone and little misfires happening on startups are disappeared.

I also want to admit that intake cam shaft sensors are different on bank 1 and 2 and this is ridiculous, there is also the 90-100 $ price difference )

So oddly enough my CEL turned off on it's own. Car runs like a raped ape just as it did before.

The CPS sensors on the N62 confuse the hell out of me. I've read (what I think) is every thread related to them on this forum and bimmerforums and there seems to be no clear concise info on which ones go where and which ones to replace when you get the code.
