Total cost $130 for 1-3/4hours labour. New parts would have cost me about $350. Getting the assembly out was the hardest part
Same happened to me last week.
Took it today to Charlie at Bimmersport and he performed the exact same fix as mentioned above in 2hrs time ($140).
It looked like a bitchen job !
