codes help
 
hi need some help with some codes. i am getting code "signal camshaft sensor outlet" and burning fail cylinder 1-6, so a total of 7 codes. i previously had 5 vanos codes but all of them are gone once i adjusted camshaft timing and vanos adjustment with proper tools and procedure. i have good compression on all cylinders and recently changed maf and fuel filter. what should i be doing next?

Have you given any thought to replacing the camshaft sensor?

What is(are) the OBD II code(s) that you are getting? The MISFIRE codes for all cylinders can be from the cam position sensor, so I suggest you get the cam position sorted out.

A misfire is defined as, "the expected work was not performed." A single cylinder misfire would be caused by factors unique to a single cylinder, but you have misfires from all cylinders so you should be looking for failures that have a global affect, such as the cam position not being reported properly so the ignition timing is wrong.

i changed the cam position sensor right now with a very low mileage one and no difference even after clearing the codes. i drove around and a vanos code popped up again. here are all the obd codes. P1397, P0301-P0306, and the new vanos code P1519. I am very confident i aligned the camshafts to the proper positions. There was no gap on the cylinder head and the special tool that holds the camshafts. I am getting very frustrated with this car. Jdstickland i appreciate your help and i see you are in murrieta is there any chance youd be able to come look at this car?

update, i just did a leak down test and each cylinder is less than 20%.

P1397 means, CAMSHAFT POSITION SENSOR B CIRCUIT, BANK 1. Camshaft Sensor B is the Exhaust Cam sensor, I'm pretty sure. Sensor A is on the intake cam, sensor B should be on the exhaust cam. P1519 is the A CAMSHAFT POSITION ACTUATOR, BANK 1.

Have you played with the VANOS? The reason I ask is because you have issues with both of your cam postion sensors. You say VANOS codes popped up, but the code trarnslators that I have don't show any VANOS troubles, you have issues with sensors.

I still believe your misfires are related to the position sensors, and you can ignore them for now. That is, when the position sensors get dialed in, the misfires will go away. Don't waste any diagnostic effort on stuff like leak-down tests because these tests are looking for weak cylinders -- rings, valves, that kind of stuff -- but you have timing issues that arise from faulty sensors.

yes i did play with the VANOS i re-aligned the gears with the special tool and adjusted the camshafts following this guide:

http://www.justanswer.com/bmw/576sv-...330i-2001.html

i have all the special tools and did it exactly to what the guide says. P1519 in DIS shows that its a Vanos intake solenoid valve out of tolerance. Also i cant not ignore them for now because the car runs terrible and even stalls sometimes. It has absolutely no power, most likely in limp mode.
