Default S54 Vanos Info Thread







Disclaimer:
Please read and completely understand the timing procedure.
Engine failures can occur resulting in having to completely rebuild the motor!
Always crank the engine by hand before starting to insure there is nothing binding, IE incorrect timing.
I assume NO responsibility if damages occur.


From Rajaie at Beisan Systems:
http://www.m3forum.net/m3forum/showthread.php?t=441481

There are 3 causes of vanos codes on this engine.
1. Failed solenoid coil pack.
2. Sticking solenoid valve body.
3. Broken oil pump driver tab.

Focus on the catastrophic stuff first.
1- Oil pump disk, as the tabs can breaks at anytime without notice.
2- Intake sprocket sleeve bolts. They usually cause a rattle when they come loose, so you have some warning. But it can be catastrophic, so a preemptive repair is a reasonable approach.
Everything else I think is secondary.
3- Solenoid coil pack. This usually throws a code when it fails. Although I know of two cases where the coil pack was installed without codes and it resolved anomalies.
4- Sticking solenoid valve body. This usually causes codes.
5- Seals repair kit. This starts providing performance improvements after 100k miles.
6,7- Rattle repair kit for splined shaft bearings and S62 diaphragm springs. This removes axial play and dampens movements to help quiet down the engine.

TIMING
If you are only performing the repairs in the S54 vanos procedure then you don't disturb the set timing and you reinstall the vanos the same way it was removed. Once the engine is started the DME will adjust the vanos timing at will.

If you are performing any repairs in the S54 vanos rattle procedure then the S54 vanos procedure will instruct you to switch to the S54 vanos rattle procedure once you perform the vanos repairs and do the cleaning.
The rattle procedure documents removing the sprocket components and performing repairs. This disturbs the set timing.
To retime the engine the vanos needs to be reinstalled with the splined shafts. This is covered in the rattle procedure. At the end of installing the vanos on the engine and setting the timing at the end of the rattle procedure you are instructed to continue in the main procedure at the section after installing the vanos mounting bolts.
Once the engine is started the DME will adjust the vanos timing.

SOLENOID COIL PACK
A failed solenoid coil pack is the most common cause. The vanos has a solenoid that is detachable form the vanos. This solenoid is made of two parts, a coil pack and a valve body. The coil pack is the electrical component and the valve body is the mechanical component. The coil pack experiences cracking connector pin solder joints at the PC board. This is caused by PC board vibration. Beisan provides a rebuilt unit with design changes to keep the problem from recurring. It costs $150 plus $150 refundable core charge. It is a very simple repair. The repair and a lot more info is provided in the Beisan S54 solenoid repair procedure, http://www.beisansystems.com/procedu..._procedure.htm

I suggest you have the fault codes read by an OBDII code reader. You can get this done for free at an Autozone or O'Reilly store. If you get a vanos electrical code, P0010, P1525, P0013, P1531, then the problem is a failed solenoid coil pack. If you don't get an electrical code it can still be a solenoid coil pack failure.

A sticking solenoid valve body is a less common problem. This can be removed and cleaned. The solenoid procedure covers this. We have been having trouble effectively cleaning the valve body. I will update the procedure soon with a more intensive cleaning process.

A broken oil pump driver tab is a somewhat common problem and is a much more involved repair. To assess if the oil pump driver tab is broken the valve cover needs to be removed and the driver tabs inspected. The Beisan S54 vanos and vanos rattle procedures document removing the valve cover and removing and reinstalling the exhaust hub that has the tabs that break.

If you get an electrical P code then you should replace the solenoid coil pack. Otherwise you essentially have two options. You can replace the solenoid coil pack and clean the solenoid valve body, or remove the valve cover and inspect for a broken tab. Most owners elect to replace the solenoid coil pack and clean the solenoid valve body because this is an inexpensive repair and they can easily perform the work themselves.

TIPS:
Broken Tabs= Turbo Toy Hub
No Broken Tabs= Beisan Pump Disc

- Highly recommend Lang Racing Cam bolts.

- Add the upper chain tensioner guide, they always break.

- Good idea to do a valve adjustment while everything is open.

- With one broken tab the car sounds and runs fine. You're just on borrowed time.
Most people are unaware they have a broken tab until they open the valve cover.

- The solenoid coil pack solder points will start to come loose, causing intermittent vanos codes.
It's an easy fix to do anytime, but easier while you have the vanos out.

- Make sure you get all the timing tools, and read the Beisan anti rattle DIY, which is the updated BMW TIS.
(You can really damage your engine if you mess up here.)

- Make sure the Crank Pin in fully inserted in the flywheel before starting this procedure.
There is a notch on the flywheel the Pin inserts into. Use a mirror to verify the flywheel is in the right location.

- Splined shaft with longer stud is the exhaust, and the shorter stud is the intake. See Pic below.

Q: What is the reason you turn the exhaust cam while removing Vanos?
A: Simply retards the exhaust side so the splined shaft is closet to the vanos, or in the fully retarded position.
This will aid in the removal of the vanos unit from the head.

Q: When doing Beisans seals and disc, could I get away with not having a cam alignment tool, and have done intake cam gear bolts?
It seems as if the cam has no reason to move and the tool is there just as a precaution.
A: Definitely use the tool. You never know if something might move and you won't know until you start the car and it doesn't run right.

Q: Is there a DIY on the chain guide? The chain needs to be removed from the exhaust side sprockets right?
A: Yes- Simply remove the cam bolts and it slides right off. Be careful and put rags underneath do nothing falls down into the engine!

Q: So once the chain is loose how do you prevent it from coming off the bottom crank sprocket?
A: Use a soft clamp to clamp the chain to the intake sprocket. Works great!

Thanks to SliM3 for this detailed Vanos info!

Naturally you have the (7) Crankshaft Sprocket that drives the two (4) Camshaft Sprockets via a (1) Double-row Chain.

The spline hubs and rear retaining rings, when torqued, provide a significant non-slip clamping force around the sprockets to complete the (2) Chain Driven Assembly. Minus the spline shafts, if you were to rotate the crank at this point, the cams would just sit still. The shafts obviously provide that final drive link to the cams (reference view (2)).

The internal (3) Diaphragm Spring Set is designed to buffer the pressure actuation of the VANOS unit. There is a friction coefficient between the teeth of the spline shaft and hubs that must be overcome before the cams will adjust. Until this friction is overcome the pressure exerted from the pistons is basically pushing the hub assemblies into the camshafts, against the diaphragm springs (reference view (2)). Naturally, when this friction is overcome the hubs sort of spring back to their initial position, the spline shafts move freely, and subsequently adjusts the cam angles.

The ultimate goal of the "Timing Procedure" is to pre-load the (3) Diaphragm Spring Set, and to a lesser degree, remove slack from the chain link/sprocket teeth interface. If not done correctly the combination of all the slack (chain, spline teeth lash, diaphragm springs) will lead to cams that will drift out of position due to the pressure exerted by the valve springs, as the assembly is rotated.

In order to accomplish this during installation the VANOS unit is partially installed, with the spline shafts [freely] rotating the unclamped hubs. The purpose of the plastic spacers is to set the initial pre-loading distance between the cylinder head and VANOS mating surfaces. At this point the two adjacent hub bolts are torqued and loosened 1/4 turn to provide a very light hub-to-sprocket clamping force.

As you continue tightening the VANOS unit bolts, you're essentially applying pressure to the diaphragm springs, just as if the pistons and spline shafts were acting against them during normal operations (explained above).

After pre-loading I removed the VANOS unit because I didn't want to use a crows foot attachment to torque the bolts. The additional leverage must be accounted for, and with torques being as low as they are, I wouldn't have been able to accurately go that low on my torque wrench.

Again, if the pre-load procedure is done correctly the cams will end up in the same exact location no matter how many times you turn the engine. Also note that the cams are "locked" into position during rotation because they're essentially wedged between the VANOS unit piston stops and the pressure exerted by the valve springs.



Cam bridge and both pins installed. Spline hub bolts loose, align chain sprocket and spline hubs so shafts engage at first set of teeth. Spline hub holes should face up.



Installed spline shafts to VANOS assembly, used plastic spacers to set pre-load spacing, spline hub bolts loose. Bridge and both pins still installed.

Pre-Loading: Tighten (2) adjacent bolts on each spline hub, loosen 1/4 turn, remove plastic spacers, and tighten VANOS assembly bolts 1/4 turn at a time until fully installed.

At this point I tightened all accessible hub bolts so the spline shafts are locked into place, removed the VANOS assembly, and torqued spline hub bolts to 12 ft-lbs with Loctite. Bridge and pins still installed.


(Picture shows the plastic spacers used for Pre-Loading)


I then rotated engine assembly roughly 15-20 times, set crank at TDC, and verified timing using timing tool. If the cams were properly pre-loaded then the holes should end up in the same exact location. The pin should fall right into the hole with no drag or force, the tool flat on the surface and overhanging on the side being verified.

If the timing tool pin does not go into the holes after rotating engine assembly, repeat the pre-load steps until it does. The slightest misalignment is enough to throw timing off.






Disclaimer:
Please read and completely understand the timing procedure.
Engine failures can occur resulting in having to completely rebuild the motor!
Always crank the engine by hand before starting to insure there is nothing binding, IE incorrect timing.
I assume NO responsibility if damages occur.

Any sure way of confirming timing and vanos are functioning optimally besides a dyno after the work is done? It says to do 200 miles of city driving but I also need to break in my clutch for 800 miles so I'm a bit puzzled as to where engine isn't supposed to be revved in the higher range for a while or not????

Thank you for sharing this but I have a question in the link that you posted of the vanos diy it shows that the guy retarded the exhaust cam before pulling the vanos completly off the engine but it does not show him putting the exhaust cam back in its original place after installing back the vanos. Is that how it is supposed to be or he just forgot about it? I'm only asking because I'm thinking of doing this in the near future and I have never done it before.
P.s. Sorry for my broken english!
