7 Series - E65 / E66 (2002 - 2008)
Discussion of BMW's 4th generation E65/E66 7 Series flagship. The E65 generated much controversy, due to its radical styling and iDrive user difficulties. Nonetheless, the E65 broke records to become the best-selling 7-series iteration ever, especially after its 2005 facelift.

"Gravel-rattling" sound from rear, near tailpipe?

Car sat for a couple of days (bad weather - rain and cooler temp). Started it yesterday evening and heard a rattling sound from near the tailpipe/muffler area. The mufflers appeared to be solidly in place, so it does not appear to be an attachment issue. Any ideas on what to check? The warranty is good until the end of June and I will be taking it to the dealer after I determine that it is consistent.

P.S. - I will get pictures on the next clear day the dealer does not have the car. TIA

A broken hanger had the same problem. Any good shop can fix with weld you wont be able to see the spot but its over the rear muffler.

Good luck.
