That fuel rollover valve behind the bulkhead can be VERY rattlley too. I tied mine tightly at a 45° angle with electrical ties to quiet it down.
Hi Ken,
After driving the M3W a good 75 miles yesterday, I think my rattling/clanking problem is not related to the bevel box or drive train. I also removed the trunk liner to inspect the drive train area from above and didn't notice anything loose or broken around the belt, etc.
The noise seems to be coming from right behind the seat, towards the upper part of the seat specifically. Is this where the fuel rollover valve is located? How do I gain access to it so secure it with a tie wrap?
Thanks for your help!
