Codes after Vanos seal upgrade

Hey Guys,

Would love any help/input one could offer.

I installed the Beisan vanos seal kit the other day, 01 330ci 150,000 miles.

The install went smoothly(I thought), cylinder walls were mint along with the pistons. The seals were obv very bad and the piston had no resistance to the cylinder.


On the first start after install I had the expected hiccup, engine idled fine after that and the car drove well.

The next morning I fired it up, got a funky idle for a moment and then engine light turns on.

Code was p0014, that code is related to the exhaust side of timing.

I reset the code, a few days later I get p0011, now this code relates to the intake side of timing.

I reset the light, the next day i get the same p0011 code again.

I had never had any timing related code before this.

Ive attached pics of the freeze frame data.



I have read about these codes, the thing that throws me for a loop is it was first the exhaust side then the intake side.


Could this be part of the break in period of the new seals. Maybe they are still very tight and the oil pressure given to adjust the timing is not enough for the freshly tight seals??

Thanks in advance to all

A P0011 DTC trouble code may be caused by one or more of the following:
-Incorrect camshaft timing
-Wiring problems (harness/wiring) in intake timing control valve control solenoid system
-Continuous oil flow to VCT piston chamber
-Failed timing valve control solenoid (stuck open)

Did you plug the solenoids back in?

Ya, plugs are all nice and snug.

Silver330,

I dont think the cam timing is physically off(if thats what you mean), never had an issue or light before seals install. Im hoping the seals are so tight (not broken in) that the desired timing adjustment is not accomplished with the oil pressure added to piston. Thus the timing (variable adjustment) is not in spec for what the DME is aiming for with the vanos piston oil pressure.

I cleaned the connectors with electrical contact cleaner.

If my timing valve control solenoid is faulty, with the old shot seals would the light not be triggered? Would it take new tight seals for the DME recognize an issue and throw the code?

as for continuous oil flow to VCT chamber, is there a way i could test this?

Also any thought on why I had p0014 on the exhaust side and it never returned, now the p0011 is popping up.


Does anyone know if it is possible to run the engine with the vanos pistons REMOVED completely?????

If i remove the pistons (or had ones with old shot seals in again) and I dont throw a code I could eliminate a few possibilities.

Did you install the VANOS spring on the correct (i.e. exhaust) side?

Yes, im certain that I did.

The car shows improvements with the new seals, until I get the light and it feels like its in "limp mode".

Did you check your cam sensor connections?

I will double check them, i pinched the female connectors a bit, hope i didnt over pinch and its been pushed thru the clip.

But the code doesnt show up immediately after a reset, sometimes it takes a day or two, and while the lights off the car has good power.

I don't know if this is the issue or not but beisan states it takes ~200 miles of city driving to break in. But it kind of sounds like the springs are swapped around? Or maybe did you twist the seals while putting them on the piston? Did you lub the seals when you put it on?

The seals seated well in piston.

I am almost positive the spring is on the exhaust side. I guess I should open and double check, I just hate having to clean the vcg, the silicone is PITA to remove for the gasket.

Is there a way I could determine if the spring is on the wrong side w/o removing the valve cover.

INPA, or any other software that can check for exhaust piston position. When cold, the exhaust timing should be fully advanced due to the spring.

Well, Ive been waiting for a reason to set something like that up (i assume its a bit time consuming to get started).

Can anyone point me to the best program and the how too. I would love a set up that can allow me to upgrade to the latest firmware, im running factory firmware from 2001.

Still trying to recall where I put the spring, I think i remember putting the spring on the side of vanos with 5 bolts holding piston cover on. Please tell me thats the exhaust side.

Also havent had engine light in a few days, I do however get the code pending tho (then i reset pending code).

Just checked Beisan procedure. If I remember correctly I put the spring on the 5 bolt side, which is intake.

Should I be happy or sad?

Sad;

I f'd up a very straight forward install that had fabulous DIY instructions, had it been another repair who knows what the consequence could have been.

Happy;

Means 'til this day I have never drove an e46 with a functioning vanos, thus drastic engine improvement await me.



Ill re do this soon.

Anyone have tips to quickly and safely remove the silicone from the valve cover gasket?

At least you're taking it in stride! Good luck and it will be faster the next time around.

In my experience dried silicone sealant is easy to remove from rubber.

Just took vanos apart again, yup spring was on wrong side.

Giving the silicone some time to dry, excited to feel the results.

Thanks to all for taking the time to lend their thoughts.

I just bought a used 2002 330i. it has a CEL code p0011. I changed the intake CPS and light is still on. I am not sure if previous owner had the vanos seals performed. I was wondering if the spring could be installed wrong. I just ordered the seals and will see if I can complete this week. I hope this is it. the vehicle runs great. It does have a slight rough idle on cold starts for about 15 seconds and then it is fine. I have never driven a 330i e46 so I am not sure if VANOS is not working or not. Thanks for posting this information. When I take the vanos off I will check to make sure spring is on Exhaust side

I did notice a change, but its not about a big power gain tho.

Since Ive owned the car I have always payed a lot of attention to my consumption needle. That has given me a huge understanding of the relationship between the vehicle speed, the rpm, the mpg needle and the road grade combined.

The vanos is now delivering the desired ignition timing, when I hold a speed on flat ground the consumption is slightly less than before. I also notice a better acceleration from 70-100km/h while burning 8.5l/100km (instant) vs before.

Without those reference points, I think the small improvements are spread out too much to "feel a power gain" while driving.

If you dont have maintenance records, install new plugs and a valve cover gasket kit while your in there.

I installed the beisan seals today. the exhuast spring was installed correctly by previous owner and myself today but I still have this p0011 code.

I changed the oil today as well. I am not sure what is causing this.
