X3 Window Rattles/Squeeks - Service Bulletin

#1
I've been googling this for over an hour, and this is the magic
bullet, the solution to an apparent defect that plagues many
X3 vehicles -- an annoying rattle in the doors while driving.

Tell the dealer to look up Service Bulletin: SIB 51 28 05.


SI B 51 28 05
Body Equipment

February 2007
Technical Service

This Service Information bulletin supersedes S.I. B51 28 05 dated December 2006.


SUBJECT
Window Guide Noise


MODEL
E83 (X3)


SITUATION
Some customers may complain of hearing squeaking or creaking noises coming from the door frame area when driving on rough roads.


CAUSE
Movement between the flocking material (felt-like material indicated by the arrows) on the window guide and the surrounding roof panel may produce squeaking or creaking noises.

These noises may be amplified by contamination or cleaner residue on the door opening.

[See Attached Image: S5106U45]


CORRECTION
In case of a customer complaint, refer to the procedure outlined below to replace the seals with improved parts and/or apply the specified transparent Teflon tape.

The flocking material was changed from Poly Amid (PA) to Poly Ethylene Terephthalate (PET) in June 2005. PET is a thermoplastic polyester with a semi-crystalline structure that has exceptional rigidity, strength, dimensional stability and low moisture absorption.

The new and improved parts may not have any unique identifying stamps, therefore the production date should be used to identify the new guides.

Updated guides will have a date stamp on the back of the part reading later than June 13, 2005 (13.6.2005).


PROCEDURE
Depending on the status of the vehicle, perform the applicable procedure described below.

A. Vehicles produced up to 01/2005, first complaint:

* Replace all 4 upper door seals with the improved parts.

o Follow Repair Instruction RA 51 32 211 to replace the front window guides.

o Follow Repair Instruction RA 51 34 211 to replace the rear window guides.

* Thoroughly clean the upper door seal's mating surface on the body of the vehicle with a silicone remover such as 3M General Purpose Adhesive Cleaner or Wurth Silicone Remover.

* Do not apply "Carbaflo" on these door seals.

B. Vehicles produced from 01/2005, and vehicles that have previously had the improved seals installed.

* Thoroughly clean the upper door seal's flocking material, as well as the mating surface on the body of the vehicle with a silicone remover such as 3M General Purpose Adhesive Cleaner or Wurth Silicone Remover.

* Apply a continuous length of Teflon tape (PN 9 407 798) to the entire contact area on the body of the vehicle, from the middle of the a-pillar to the top of the c-pillar.

[See Attached Image: S5106U48]

Notes:
The tape should be applied slowly and very carefully to avoid trapping air bubbles under the tape.
To eliminate visibility of the tape when the door is closed and ensure proper contact with the flocking surface, the upper edge of the tape (1) should line up evenly with the top of the door seal (2) for the entire length of the applied area.
The tape should be applied in its full width (16mm), not be cut down to a narrower width.


C. Vehicles produced up to 01/2005, which are in for a repeat complaint, and still have the original seals installed

* Replace all 4 upper door seals as per procedure A.

* Apply Teflon tape as per procedure B.

Good post, and I'm sure the people with X3s that have this problem will appreciate it. Back in 2005 (and also early 2007) when I had X3 loan vehicles, both cars had horrible rattles in the windows when covering rough, or somewhat rough roads. This is one of the reasons I chose not to get an X3 3.0si when I had my 07' X5 taken back.

Good work!

Yeah, we're about to pick up a used X3, and also noticed all the
doors rattled when driving over even the slightest bumps.

Also, after further googling, I came across this post regarding the
above "solution":

Changing the door seals will never solve the problem, because the material
that BMW spec'd for the seals will still make noise with the replacement seals.

My X3 is dead silent. I wipe the door seals a couple of times a year with
Meguiars NXT Tech Protect on a rag and it instantly stops the squeeking and
it generally won't start coming back for at least six months. It seems to have
a cumulative effect as well, since each time I apply it it seems to take a
month or two longer before the squeeking shows faint signs of coming back.

I thought I was pretty clear in post #4. Spray some Meguires NXT Tech Protect
on a rag and wipe ALL the seals, including the flocked [fuzzy] seals around the tops
of the doors (they're the most important ones). Wiping the flocked seals only
should solve the problem, but I do them all because the treatment is good for
the rubber in the long run. The squeeking will disappear instantly, and if
you do a quick wipe every four months or so when you're doing a quick detail
of the interior it will stay gone.


The Service Bulletin above from BMW is a fairly aggressive "fix" as it's several
hours of labor, and they rip off all the factory door seals, install "fixed" seals,
and then apply teflon tape to the body paint around the doors.

I think I'll try "Meguiars NXT Tech Protect on a rag" before having the
dealer rip apart my car.

Did your X5 sqeek/rattle?
 
#4
None of our X5s squeaked or rattled. We had a 2004 X5 4.4i and a 2004 4.8is and then the 2007 3.0si. They felt like tanks, and were very, very quiet. The doors on the 07' X5 are so heavy & solid!!
 
#5
Just an update, I followed the posted advice below, using Meguiars NXT Tech Protect, and
the "rattle" (which was just a very brief squeek that sounds like a rattle) is completely gone.

I applied the stuff months ago, and the rattle is still gone.
