B-Pillar Road and Wind Noise
SI. No. 811-2156PI No.
Date: July 1999

Road and wind noise from B-pillar
Cars affected
Saab 900 CV M95-M98
Background
On certain cars, especially if the weatherstrip between the door and the B-pillar is too short, irritating road and wind noise can penetrate into the cabin through the cover at the top of the B-pillar.
Customers may think that this noise is coming from the seal between the side glasses but it is actually coming around the bottom of the door.
By replacing the cover with one of a new design, the noise can be reduced while the fit and appearance is greatly enhanced.
Proceed with these measures after customer complaint. Both sides should be done at the same time.
Parts required
51 12 776 Cover, LH (CA: 30581532)
51 12 784 Cover, RH (CA: 30581533)
43 45 872 Plastic rivet (4 pcs) (CA: 30550549)
Procedure
Always perform this procedure on both the LH and RH B-pillars.
1. Open the door and lower the rear side window.
2. Remove the three plastic rivets.
3. Loosen the top of the door seal to access the cover.
4. Remove the cover.
5. Carefully cut off the top of the door seal with a pair of scissors where the seal changes from a profile to flat, see illustration (just above the pebbled grain.)
Important:
If the door seal is cut too far down, the metal reinforcement in the seal will be exposed. If this is the case, the metal must be painted to protect it against corrosion.
6. Place a new cover on the B-pillar. Insert the cover from the side, making sure the metal hooks on the back of the cover fasten onto the B-pillar.
7. Fit two plastic rivets, part no 43 45 672.
8. Check the function of the door and the rear side window.
