Dear all,
I have recently bought a pre-owned e60 523i 2005, and it suffers from the famous "vibration when idle", specially first 10-15 minutes of drive.
Doesn't matter if it's on D or P or Neutral. Vibration is noticible when I touch steering wheel or other interior parts, usually it's not permanent, it's like "waves" and not too big. Also the driver seat vibrates.
I know about SIB 180208 (exhaust brackets replacement) as the possible remedy, but my BMW dealer doesn't accept this and doesn't want to fix it.
My question is the following: Would this vibration cause later bigger problems if I don't fix it?
Thanks alot,
Rouzbeh

I wanted to bring this issue back up for those who are/will experiencing same problem. If your car is giving you the "droning" sound and vibrating at idle, take it to your dealer and mention this service bulletin.
Service Bulletin 18 02 08
Customer may complain of a slight vibration and/or droning noise when the vehicle is idling in park, neutral, drive and reverse when engine is at operating temperature.
CAUSE
Insufficient vibration dampening of the exhaust system.
PROCEDURE
1.Verify the complaint. Vibration/droning is most prevalent when engine is at operating temperature.
2.Remove the lower bracket for the exhaust system. If droning/vibration is gone, proceed to step three. If vibration/droning still exists with the lower bracket removed; continue troubleshooting exhaust/driveline for other causes or conditions
3.Remove complete bracket assembly and replace it with the bracket (1) PN 18 20 7 521 346 using two new ASA bolts (PN 07 12 9 905 417. Tighten to 21Nm.
Install front pipe bracket (1) PN 18 20 7 521 347 with four rubber bushings (2) (PN 18 20 7 546 579) to the new 346 bracket with two ASA bolts (PN 07 12 9 904 559) and two nuts (PN 07 12 9 904 580). Tighten down to 21Nm
After performing this procedure the vehicle will exhibit the same amount of normal driveline vibration as a comparably equipped E60 with a M54 or N52 engine."
