E60 - vibrácie a hrkalka na voľnobehu

Sobota, 30. Júna 2012, 21:17

Problém hlavne pri zohriatom motore - nepravidelný plechový hrkot a vibrácie, spôsobené rezonáciou výfukového systému.
Vraj častý problém.

Znenie od BMW:

"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."
