Recently I got a new code and several new symptoms that my car never had before.

I start with the codes:
P0313 - Misfire... I had that before... Still can't rid of it, but I am not really concerned about it much.
P0365 - Camshaft Position Sensor B Bank-1... Now this one is new! I never had it before.
P0430 - Catalyst Eff... I had this one for a while... Couldn't figure out the reason... Some say, O2 sensors, others say exhaust leak... Couldn't find exhaust leak... so probably just need to change the O2s.

Anyway, P0365 is a new code and here are the symptoms that I started having:
1. Between 55 and 65 mph, car starts shaking very noticeably.
2. Acceleration! Sometimes it is awesome... just like any Bimmer should be, but sometimes is it horrible! You press on the gas and press... and nothing... and then suddenly the rpm just flies through the roof.
3. When I break, the car gets shaky sometimes.
4. Sometimes, rarely, I have a bad start, kind of hesitated.

Now, I had a bad oil leak from my VC. And on the camshaft seonsor, was a little oil... I cleaned it out thoroughly with the electrical cleaner though... but it didn't solve the problem.

My Vanos seals are new, fuel filter is new, fuel pump new, spark plugs new, coil boots new, VCG, oil separator, NO vacuum leaks, oil is fresh... Just in case for you guys to know lol

If anyone has ever had this P0365, please chime in. If anyone knows of symptoms of bad cam sensor B bank 1, whatever that is... chime in!

Thanks in advance!
First off get your o2 sensors replaced, atleast the precat ones(though you are advised to change the post ones aswell).
Failing o2 sensors will fool the EMS that your car is running lean and will dump alot more fuel into the engine , giving sluggish performance and lots of other cons aswell.

The cat's in these cars last a lifetime , no need to go spend money on a new manifold before you've replaced the o2's.

As for your symptoms:

1. Tires,driveshaft or any driveline part can do this, most often it's unbalanced tires or a bad wheel bearing (but that would be audible and constant)
Anything you feel or hear at a certain speed is not related to the engine, if it's at a certain RPM then yes it's engine.
2. Camshaft sensor, stock EMS defaults to 360 degree engine cycle instead of 720 degree cycle, meanig alot less performance.
3. FCAB's or your front rotors are bad.
Do this to see if it's the FCAB's (or jack the car up and shake the wheel with your hands at 9 and 3 'o clock, if you can the fcab is bad)



4. Camshaft sensors again.

The B sensor is the exhaust side sensor.

Same thing as you had, VCG leak poured into the sensor and connector.

I ordered the sensor, o-ring and the bolt from fcpeuro.
Went to replace it, but for the life of mine couldnt take the stupid bolt out. Frustrated I just cleaned at connectors and the sensor harness with MAF cleaner.

The light has been off for me for almost a week, hopefully it will stay off. Else I do have the sensor, o-ring and the screw handy. But that 5mm hex is driving me crazy. I already dropped one 5mm allen key into the underbelly, I have one more but it just doesnt budge. **** scared to strip that bolt as well.
Get yourself one of these :


You'll thank me if you ever do some maintnance on your car
