I had mine replaced early last month, was much worst
its a 2007
they say it happens often
they seem to say that with a lot of the little annoying bugs,
like; suspension leveler, comfort access, clunk in the trunk, side stiching on the seat giving up, auxiliary pump noisy(replaced)
I must be up to 9-10 visit since january
tried to resell for a 535xi and after 20 months the car is worth only 46K, paid 72k, was listed as 81k, and risidual on tyhe 535 for 36 month lease is down to 49%
they say thay can't resell as well as before
no wonder, with all these issues....
