Bouncing windows saga (again) FFS

As the weather has now turned cold, i thought it was time to let BMW have my E89 back so that they could sort out the window bounce (when putting the roof up).

The dealers had it for 3 days and carried out lots of test. Even after carrying out a "guided test" they found now't wrong. They did remark that there was some sort of residue in the window channel on the drivers side. cleaned it, and pronounced it cured.

My service rep (Rob - really nice guy) didn't necessarily believe that the problem had been fixed. Still i want this investigated before the warranty ends at the end of December.

I said i'd take it and report back. Strangely when i opened the boot i noticed that the load cover was in the open position and the umbrellas i had been using a few days ago, were in the same position as when i dropped off the car. This got me thinking that the dealers had probably only tested the window up/down without lowering/raising the roof (which is when the problem occurs!). That will be 3 wasted days then!

When i got home, i called Carrie to come and film the roof up process as i believed that it would once again have a bouncing window.

Low and behold...... yes the o/s window bounced all on film. As the dealers had left their key dongle on the car key, i thought i would take it back to them and show them to footage. They have asked for a copy of the footage so that it can be forwarded to BMW.

I have spoken to them many times regarding the cure being the rear window delay, but to no avail. I will keep trying, but before it goes in again, i will want to know what they intend to do, and to insure that they support warranty on this problem beyond the warranty period.

If there is a TSB and somebody know the details of it, i would appreciate this information.
 
this was happening to me today as i was closing my windows as i was raking the key out. it has happened on occasion previously but i've not really been overly concerned with it but yeah it can be annoying

might be worth presenting the dealers with this vid and asking them if its a red only afflication :rofl:

I get the bouncing windows occasionally but just reset it and it will be fine for ages then becomes random again. I've never had the problem though with raising the roof. I think its a problem that BMW will never resolve. My 2003 MINI Cooper S was exactly the same and my Z3 will occasionally do it and that doesn't have the drop window facility.

Good luck on it though.

Err thats my car in the video.... tit :D
 
well it would of helped if you had posted your vid. that could of been any old numpty :P
 
I have had this on occasion. Someone mentioned having a relay fitted that delayed the rear windows raising until the front ones are up. I think the theory was the fronts reacted thinking something was trapped when they contact the rears. When I went to bmw I ended up with a new window motor. After this it happened again but hasn't done it for a while now.
 
Can the roof position be adjusted? It seems that when the roof is in place the rear window may close a little further forward and causing it to trigger the anti trap feature on the front windows. Maybe the glass positioning can also be fine tuned?

I used to get bouncing windows regularly when putting the roof back and took it to the dealer about 10 months ago. Since then,it's not reoccurred once. I think what is quoted above is what was done to mine as the front and rear windows used to rise simultaneously, but now the rear ones start rising a split second after the main ones.
 
update!

They are having the car back for 3 days and replacing the window motors on both sides of the car. We will see!
 
Yep - it is a relay addition that is required. There is a BMW number for the work required so your dealer should know it. I will try to find the specifics on an old thread.
 
From Bimmer forum - There is a standard fault code for this issue now on the BMW system, its called
Measure No 32795976-01

The part number for the kit is BM51337308822

From http://e89.zpost.com/forums/showthread.php?t=741304 Just had mine fixed a few weeks ago. The TSB referenced was 511011. Writeup by the technician; "I checked the JBE hardware number and found number 2 is installed and vehicle needs JBE3 as per bulletin 511011. I replaced the JBE with JBE3 and performed coding session."

The rear windows now close AFTER the front windows and I have not had the problem since the repair.
 
I can report that the car has been re-coded and the fault paperers to gave disappeared.

Its clear that the rear windows now lift momentarily after the from windows. the front windows hit their top position and then the rear windows close just after them. I suppose the anti trap feature is not initiated now and all is well.

They have also reprogrammed the DCT. when i get it back after the new year (got their 3.0d 5 series GT until then. Its a bit of a drug dealers car IMHO).

We will see. if its ok, ill put back the smartop module.

Unless they have fitted the replacement relays iaw the info I posted earlier I doubt very much that the fault will have been cured.

I will keep an eye on them, but as I said, when I tested the closing the windows operated quite differently. Front closed before rears. You never know, they have possibly rewritten the code and now there is no need of the delay relay as that might have been a temporary fix until the software was modified.


Besides they still have my car and I still have their GT. It's only been since the 18th. This way there's fewer miles on my car :-)

True about the possibility of the code having been rewritten. But it would have been a lot cheaper for them if they had done this in the first place.
