I'm going to loosen all cams, do the Besian procedure, but when done spin the engine by hand and double ck.

Yes, exactly. This is required. When you are done and everything is *right*, after turning the crank two revs every alignment should come in at the exactly the same time. With the crank pinned and holding the intake cam hard retarded, you should be able to push the cam block towards the back of the head with your finger tips, and then pull it forward onto the cams with no effort or wiggling. At the same time, the wheels should line up centered. Hitting the exact sweet spot on all four cams is bloody hard.

I'm bouncing back and forth between bmw, and Besian, Raj job was just vanos my job was all chain rail etc, bmw wants damper loosen? No idea why don't want to do that again. I'm loosening gears.

I'm bouncing back and forth between bmw, and Besian, Raj job was just vanos my job was all chain rail etc, bmw wants damper loosen? No idea why don't want to do that again. I'm loosening gears. Starting to think bank 2 cam chain to crank was to tight so when I torque vano restarted I'm just pulling chain not bottoming vanos, throw that theory out! Spun vanos with slack it's bottoming out. Still thinking it the cps wheels being off, I'm taking my time on this one before it goes back together. All looks right. All back together removed pin and cam blocks rotated engine with plugs out several time put pin back on cranks, cam blocks, cps jig, all lines up. I did notice bank one vanos was more active the bank 2 solenoid's are both out, not sure if they both should be so lively when pulling through by hand?

Talked again to Raj, 4 other people are running into this problem, huge difference between jig, and timing cover alignment holes, I'm thinking I need to learn about cam adaptation, basically wich way to turn cam position wheel. I have a launch tool software version 3.23.00 hardware version 2.0

That what I been going by, thanks

[rf900rkw]

Damn automerge.

What type of Launch is it, exactly? If it was the X431, it would be giving BMW-FC codes rather than OBDii. Thus I don't think it will help with adaption. But just in case. If the adaption numbers are positive, the trigger is retarded and needs to be turned clockwise facing the motor. If they are negative, the wheel is advanced and needs to go counter-clock.

Just to add to the fun, during the great beta test of 2012, Raj sent me his tool kit to compare to the one I had from eBay. The cam blocks were the same, but the wheel timing jigs were different, and they ended up with different timing positions. I seem to remember 3 degrees, but don't remember which tool set was which.

Hi Randy, its a Launch Creader V, does some streaming data but I don't think it can read this value. Crank is pinned on tdc. Just can't post more then 5 images. I might have mentioned the also the tools are from the company on Besians website. I rotated it several times its looks perfect.

[rf900rkw]

Nope. The CReader is a very nice little generic OBDii scanner. You need something that is BMW specific. Probably the easiest way for you to get direct access to the data stream is to build your own INPA scanner. You can snag all the pieces from eBay, or get your own pieces from our Diagnostic Forum. Then, once you have INPA up and running you STILL won't be able to see the cam adaption values, because INPA isn't programmed to show them. But, there is a program called "testo" that uses the INPA programming stack and does.

[scottrutherford]

I'm trying to get another scanner as we speak, from my friends shop, it's a Autel maxidiag elite

[rf900rkw]

Never used an Autel, but have heard good things. It should have the data needed.


Is the car back together now? If so, how did you time it and what happened?

[scottrutherford]

Timed it just as you described rotated it through and its all locked in back in time, I have not put valve covers etc back on those pictures are how its sitting right now. I'm gun shy about putting all the covers back on, I've been just getting ready for the same codes again and planning for that to happen, and having a good scanner available at my disposal.

Here's a link to the m62tu engine if you're interested.

[scottrutherford]

Didn't ohm out on either one, could have put 200ft lbs on vanos unit and it wouldn't have matter when I first attempted the job I even replaced the battery's in my meter.

[rf900rkw]

bump just cause I hate automerge!

[scottrutherford]

Spun engine over several more times putting it all back together, I definitely have a difference between upper timing cover cps holes and the jig, it all lines up nicely though. With tool set perfectly. See in a bit what codes I get.

[kimokk]

Are you saying when you reach TDC the two vanos cam sensor wheels don't line up? The passenger side sensor wheel is going to be off due to the spring loaded advance of the cam when you remove the cam blocks.

[scottrutherford]

All tools locked in cams, crank, cps wheel tool, and if if take out jig for cam moves that's normal, picture I posted last night look just like instructions

[kimokk]

Yep. I'm wondering if the bank one inspection hole is made for that cam spring advance? I would think it should be and wouldn't affect the bank two position either.

[scottrutherford]

I was thinking the same thing

And?

[scottrutherford]

Home again started car still on jacks warned up bled coolant system only bank 2 0021 code it's those damn triggers.not bank 1 though. I have not driven car not going to bother until this is resolved. Half vanos system seems working. This is out of useless Bentley manual p0021 over advance bank 2, code P0022 over retarted both codes clearing haven't driven but did many cycles and brought up to normal operating temp, codes are clearing numerous starts and cycles, and have held rpm in the upper range. I'll put it on its feet tomorrow, and see what is triggered.

[rf900rkw]

Bentley is incorrect. Or rather, incomplete. The OBDii definition is "Bank X cam over advance OR system performance. ". The BMW FC code is 34. Of course 34 equates to P0020, 21, and 22. And as is often the case, BMW took a bit of liberty with the code application. The actual logic behind the code is as stated before. More than +/-10 degrees error while the system is off/retarded.

Did you get your hands on that Autel?

[kimokk]

I just finished helping a guy with his timing chain guide rails. Did the vanos timing and had good continuity throughout and still got the vanos camshaft control on bank 1. So frustrating!

I had a peake code of OF 21 which is a p0011 OBDII code.

[rf900rkw]

BMW. Tools normally give the code in decimal. Peake and a few others give the same except in hex.

P0010/11/12. = 33 decimal. 21 hex

P0020/21/22 = 34 decimal, 22 hex

[kimokk]

Yes we have the dreaded p0011 code too. And this was with good continuity. Is there a technique when removing the cam blocks on bank 1 since the vanos cam springs forward and slackens the chain on the u rail?

[scottrutherford]

Ok p0021 means 34 decimal or 22 hex , so retard timimg wheel 1/8"of a inch or a little more then a 1/3 of a milimeter, can you explain that a little more I've never heard those terms relative to a cam. I will have the Autel by tomorrow and this is over most of my mechanic friends heads and seems over mine. I'm just very stubborn and never quit
