My Ride: 2000 BMW 328ci
Camshaft Position Sensor

I have a 2000 328ci with 160,000 miles and The recent symptoms of my car in the past month are:
-Stuck in fourth gear a few times along with CEL (now use steptronic daily to prevent this)
-stalled out at a traffic light the other day when I let off the brake to start driving
-rough idle and RPMs drop drastically sometimes while rolling slowly
-periodical significant loss of power (no "get up and go")
-check engine light can't decide whether to turn on or off

So I took it to my previously favored shop and they called within the first day saying I needed an entire transmission. $2800. I'm no mechanic, but I thought that was a load of crap since I can still shift the car fine using manual mode (it's an automatic). It returned to normal for a while, but now has the loss of power and even stalled once at a light. The CEL was off but I was still able to get the code reading:

P0340- Powertrain
Camshaft position sensor "A" circuit (bank 1 or single sensor)

When I researched this code, it said getting stuck in a certain gear and stalling or loss of power was a symptom. Has anyone else had similar experiences? Should I just replace the sensor? And if so, would it be the exhaust side or intake side?

I'd definitely try a new sensor. Replace both if you can afford it. Otherwise, I think that's the intake. Get Siemens VDO (OEM) brand or Genuine BMW ONLY! rmeuropean had a good deal last I checked. They were just labeled OEM. They're Siemens.

Bank A is intake. I've been there, lost power brakes and steering as I faced a right turn downhill with a wall approaching. Wouldn't wish that on anyone

I found a VEMO one for $50. Are these known to fail?

Buy OEM or Genuine BMW, there is a reason people tell you not to buy aftermarket, they don't work.

As WD said the OEM Siemens are cheaper at RMEuropean than Meyle or Vemo elsewhere. They've been redesigned since the car was manufactured so expect them to look slightly different.

Camshaft Position Sensor

Only buy OEM / Genuine BMW camshaft and crankshaft position sensors to avoid problems. I think most people who say this have lived it.

Cam is up top. One on passenger is exhaust. One on driver side is intake. Crank sensor is down low in the back near the starter and transmission bell housing.

Camshaft sensor on the intake is an easy DIY. only tool I had to buy is a 32mm wrench. Also having one of those flexible grabbers helped a lot with running the wire.

FCP euro has a sale on the Febi (OEM) for 50$. I bought/installed it and it was clear that it was a genuine BMW one with the logo scratched off. Any reason why this wouldn't be as good as Siemens or Genuine?

Febi isn't the OEM or even AN OEM on the E46. It might have been a mislabel on FCP or they're just reselling Siemens/BMW sensors.

No reason to get from FCP if they don't carry Siemens. I know everyone here loves them, but even with the lifetime warranty you're still spending more for an inferior part with an increased chance of being stranded. No thanks, 2 year warranty is good enough.

I just checked. The brand is listed as OEM- the reason I was confused was because it came in a Febi box for some reason. There is most definitely scratching off where the BMW logo would be though.

In my opinion, given how easy and quick the job is, no reason not to get this one with the lifetime warranty and replace it if it starts giving problems again.

When they say OEM they mean it. Sometimes they can't put the brand due to sales agreements but OEM is accurate.

The original cam shaft sensor that came from Germany in my 2003 330i was stamped FEBI with a BMW part number also. When I sought out a replacement a few months back I ordered "Genuine" - which was also listed as FEBI. Like many parts, to avoid production interruptions due to supplier issues there may have been multiple oe suppliers.

There's a thread on here from 4 years ago asking this very question that ordered several oem cps from pelican etc by various members. They all came in Febi packaging with the rounded scraped off.

I always assumed Febi was some cheapo repro brand like Uro (not to bash Uro, I have a few Urop parts I've been happy with)
Never realized Febi was an OE supplier
