Checked it. Don't think faintly is quite right because I can hear mine really clearly haha. Sigh not valve body or solenoid then I guess

At that point, the piston is sitting not flush with the back of the bore but rather it is sitting touching the end caps, so the piston is slightly less than flush.

Can you elaborate on the tensioning of the diaphragm springs? Is the purpose to keep the splined shafts from accidentally moving the hub while you are tightening the rest of the hub. I set up both intake and exhaust of my VANOS the same way so I would expect the timing to be off on both sides? Also, I got the same results whether I tensioned the diaphragm springs or not;

Again even after car had run, the process for removing the vanos with properly timed engine should always yield the same piston positions. I always lock the crank at TDC and then fully retard cams before removing head. There is no way that I'd be able to retard my intake cam enough to have the piston as retracted as yours. Mine sits perfectly flush whereas yours is considerably protruded. Your exhaust cam looks like mine does before I turn the cam with wrench again with crank locked.

The diaphragm plates basically act like clutch and pressure plate to help keep the cams in the desired position. The piston has to overcome the pressure to advance or retard the cams. If the hub bolts aren't tensioned properly than the Pistons can't do their job properly.

Default Re: VANOS P00012 code, no intake movement

wait by protruding do you mean how my piston is pushed into the bore as opposed to being flush with the end of the bore (the end where the end cap attaches to)? If so I am not sure how to fix that because the end cap geometry causes the piston to be pushed in, as there is a boss on the inside of the cap.

Regarding the way of putting the splined shaft in first and checking that the teeth are protruding from the hub, this is what my intake spline looked like after I torqued down everything (VANOS, end caps, hub bolts). I think that matches pretty closely with how the spline should look using the method of putting the splined shaft in first.

Default VANOS P00012 code, no intake movement

I am talking about the picture of the intake piston you posted which looks to be extending a 1/2 inch beyond flush towards the front of the car.

How about posting some additional pics.

Lock crank in TDC and then rotate cams counter clockwise to fully retarded position. Then snap a pic of the backside of the two Pistons with end caps removed . They should be sitting flush. Also timing bridge should slide in ..

Sounds good. I will post pics when I get home to my computer.

Ah, the 2nd picture with it extending all the way down the bore is the exhaust side. I was just showing the position of the pistons after car shutoff.

Actually I have never been able to successfully rotate my cams while the hub bolts are on. Maybe it has something to do with the S62 diaphragm plates I have on there. I didn't want to yank at my engine too hard so I've always just loosened the hub bolts first before turning the cam when removing my vanos. VANOS adjusts during normal operation though, so its not seized.

Default Re: VANOS P00012 code, no intake movement

so sorry

I finally looked at the pictures on my cell phone. Intake piston looks spot on. Your exhaust piston makes sense too if you're not able to retard the cam.

What torque are you using on the hub bolts?

Default Re: VANOS P00012 code, no intake movement

A question about timing and its relation to adaptations. Say I have the following conditions:

Actual 49
Pilot DME 52.5
Adaptation -7

What does this actually all mean? So how I understand it is 49 is what the camshaft is actually at, 52.5 is what the VANOS wants, and the VANOS is retarded an additional 7 because the cam is 7 ahead of the crank (this part is where Im iffy on). Also, what does CR mean in GT1.

Im curious because assuming I did not clear my adaptations (I thought I did but I cant find the screenshot to show it now so I wonder...), if I put my car together and timed it spot on, would the car be throwing codes. At the moment my intake goes up to 50.8. I am wondering if the -7 adaptation is causing me to be out of the intake tolerance band.
