Ok...I have this code that popped up, and I am wondering if there is a BMW Tech in the house that can help me pinpoint it out...

Code P1519

it popped up right along with O2 sensor codes...I was told it was a VANOS issue?:help :dunno

I believe that code would be "B Camshaft Position Actuator Control Circuit Signal Low (Bank 1)", which sounds to me like a problem with the exhaust camshaft position sensor.

Are you reffering to #17?
It cant be cause I replaced it when I did my cam swap!
but sh...you belong to BMWCCA so I cant argue that...

Do you have Double VANOS?

no...aint that found only in euro's?
I have what's pictured...

Seems to me that particular code should only be from a dual vanos engine, which you don't have. That makes me suspicious of the scan tool used to pull the codes. What did you used to scan the car?

You've done a cam swap and that makes me suspect that the VANOS & cams aren't properly timed. It is very difficult to have that job come out right without having all of the BMW special cam & VANOS tools. Were those used for the cam swap?

Yea I have the special tools specifically used for timing...and I took it to AutoZone to scan it...they use that orange looking tool...

328 single vanos? I thought all 328 shipped with M52 which I suppose is DV.

DV mean vanos on both cams right?

yup. DV = Double Vanos.

Ah, that is a generic scanner and I've seen them produce invalid results on BMW's. Have the car scanned by someone with a full-up BMW specific scan system (DIS, GT-1, MoDIC, etc).

I think the Double VANOS started in '98 on the 328, but apparently early 98 328s had Single VANOS.

P1519 is ""A" Camshaft Position Actuator Bank 1" or "VANOS Faulty Reference Value Intake."

""B" Camshaft Position Actuator Control Circuit Signal Low Bank 1" is P1529.

So, the OBDII code does point to the VANOS on the intake camshaft and it seems to point to the CPS.

wow that sux...cause I just replaced that not too long ago...with a new one too...not used!!! wtf!
ok so that would not trigger a false code with the O2 sensors right?
dang!
thanks guys!

The O2 sensor code may be trigered by incomplete combustion of some cylinder charges due improper cam or spark. The ecu not knowing what cycle he's on for a few turn and messing up the events. Does it misses sometimes ??

///Menace328i

it never misses! it runs aight! so you are saying that the CPS is the one at faul after all...and also responsible for the O2 codes that might be false?

Well if one could trigger the other it would be this way, so I think I would take care of the CPS first to see if this clears up not to change a working O2 sensor, I still would not rule out the possibility of bad code reading or having two different problems.
Edit: I just read your signature and you replaced your cams ?? There could be a difference between the s50 cams CPS and if the ECU is not picking up the signal at time it's expecting it, it may trigger a stuck vanos CEL Same goes if the cam is off.

so now what do I do? get a CPS for a S50 engine? :dunno

I don't think it will help, I'm not a Cam expert, you need more input from someone that have the full understanding of the ECU CPS interaction. Hope someone can chime in and enlighten us. That code have been an issue on some aftermarket cam, the grind was right on bun on a batch the ECU did throw the stuck vanos CEL.
