UPDATE: success!

Hi Rajaie,

after following all tips mentionned to check things and finding that my intake/DISA, ... are ok, I decide to do the following:
1. reset Vanos adaptation in INPA: No change, car still suffers hesitation,....
2. update my DME with most recent version using WinKFP and reset all adaptations in INPA: SUCCESS !

Dont know if the DME udpate or the complete reset did something to help, or am I still in the "placebo" phase, but the car doesnt have any hesitation whatsoever !!!

I decided to do the update after reading some threads where some non ZHP owners had their DME udpated at the dealer. Lets see if anything comes back, I am curious if the car re-adapts or relearns something that is bad ...

List of things changed in order: VCG, spark plugs, Fuel pump/filter, Vanos Seals, DME update.

Btw, I got Inpa and Dis working. There faults related but I erased them and will monitor for the future. Here's a pic of the Vanos params whatever they mean....
Have you tried slightly crimping the solenoid electrical cable connector pin receptacles? This creates a better connection and has solved hesitation problems for others.

yes i tried that shortly after the Vanos replacement, didnt do anything ... in any case, dont know how it could have helped, take a look at detailed pics I took of a socket pin i baught because i was very curious about that. You can click on the album link for more pics. Of course, many weird things can happen, but that socket pin is designed in such a way to prevent it from coming loose...

Smile Vanos Repair completed

Raj,

I bought the new rings last year and finally got around to putting them in. Thanks for the rings and writeup. Beside the ton of parts you have to remove, installation was pretty straightforward. The reward was more power at the low end.

I wasn't getting any errors but the old rings were cooked.

Rajaie,

Whats your take on slow response times on an S54 motor after running the VANOS test?

DIS says to check the check valve or replace the solenoid pack. I thought I would run it by you before going further. Is this indicative of solders gone or going bad on the soleniod pack?

Thanks

The check valve would be part # 1 on this diagram

Sorry, I don't know.
The solenoid problem usually coincides with a fault code, but it's reasonable that it might initially degrade function without generating a code.
That oil regulating has been known to fail on the S62 engine (E39 M5).

I recently communicated with an owner who had DIS vanos test degraded performance and was going to try the rebuilt solenoid. I don't believe I've heard back from him.

Was the problem on the intake or exhaust of both? Was it slow response time or off positioning?

Please let me know what you find in the end.

Another Project Done - VCG, Vanos, Plugs

Well...I'm just about caught up on the '01 330xi I bought about 6 months ago. It had come up for an Inspection so I went ahead and did an Inspection II. I noticed a little bit of oil around the VCG so I decided to go ahead and replace it and while I was in there I might as well do the Vanos seals as well.

Everything went really well with no surprises. I simply followed Beisan "how-to" for the the replacement of the Vanos seals and everything else just fell into place except before I pulled the Valve Cover I replaced the spark plugs. Everything inside looked great with no real sludge or foam stuff like I've seen other people post. For 170k, it makes me feel much better about the condition of the engine. I did take my VC and clean it up using a parts washer and got it looking almost brand new. Got it all put back together, took it for a drive and everything seems to be good with no CELs. To early to tell if the Vanos seals did much yet, but the idle seemed a bit smoother, but then again may just be my imagination.

Anyway....my DIY with my car is taking me places I never thought I'd ever even attempt. Since I bought the car I have done a cooling system overhaul, brake pads/rotors, front axles, CCV and hoses, VCG, Vanos, plugs, and intake duct replacement. I've learned a lot and have been enjoying getting my hands dirty.

I know what you mean....I'm in the process of doing a complete cooling overhaul, which I never whould've thought I'd be able to do, but so far there have been no surprises, thanks to people on this forum and the Bentley manual Getting the hands/arms dirty is a bonus to show that you've been working hard!

bimrdreamr, did you buy all the parts recommended in the Beisan guide? I'm ready to do my VCG & Beisan Rattle & Seals.

I have this listed out for parts to buy:


part - qty - desc
7510017866 - 2 - oil
11121437395 - 15 - seals
11129070990 - 1 - valve cover gasket

besian
11361433817 - 1 - vanos gasket
32411093596 - 2 - vanos oil hose washer
11127526447 - 1 - oil fill neck gasket

breakables
11361748745 - 2 - vanos piston bolts
17111712963 - 1 - fan shroud rivet


Any of these not needed, any other parts needed?

I have this listed out for parts to buy:


part - qty - desc
7510017866 - 2 - oil Not sure what that is. If it is engine oil, I had to add less than 1 qt back when finished.
11121437395 - 15 - seals YES
11129070990 - 1 - valve cover gasket YES
11121730352 - 4 - Rubber Grommet (Goes under the cover...I was apparently already missing one.)

besian
11361433817 - 1 - vanos gasket YES...I almost missed this and ended up having to get from the stealership
32411093596 - 2 - vanos oil hose washer YES
11127526447 - 1 - oil fill neck gasket YES

breakables
11361748745 - 2 - vanos piston bolts I did not order these nor did I have any issues...I'd say that is your call. Cheap insurance.
17111712963 - 1 - fan shroud rivet Again, I didn't order any of these. As many time as I've had the shroud off I haven't come close to breaking one. Again...personal call on this. You should be able to skip IMHO.

Don't forget you will also need some high temp RTV. Also make sure the small oil container you use is fairly shallow or else once you get oil in it from the VANOS you might end up spilling oil everywhere when tilting it to get it out. Also you will still end up getting oil leaking down the front. Make sure to cover up the belts and hoses below well because the oil will easily soak through a single rag. My recommendation is cover with a plastic bag and then cover that with a few shop rags.

Any of these not needed, any other parts needed?

Where did you buy your stuff from? Looks like RMeuropean or BMApars seems to be the cheapest...but shipping is expensive.
