Two weeks ago, while returning from the breakfast meet in Pearland, my travel cover blew out from underneath the bungee-cord cargo net on the passenger seat and got wrapped around the rear wheel and final drive. After cutting the remnants loose (on the side of the tollway, not an enjoyable place) and finding oil dripping out of the final drive, I decided to go straight a dealer. I chose Mancuso as they were only 1 mile further from me than home was.
On dropping the bike off that Saturday, I was told they wouldn't be able to look at it until the following Tuesday or Wednesday. No surprise or disappointment there, shops tend to be backlogged.
Flash forward a week, after no calls from them I call them and get various stories; 'need the wrench to remove the wheel', 'need a specific wrench to disassemble the final drive', 'the wrench was lost as they 'just moved from their old shop'.
Flash forward another week (yesterday), and I call them and it's the same song and dance ... with no, NO, estimate of how long the diagnosis will take.
So, this morning I saddle up the trailer and go pick the bike up and transport to Wild West. Got a call from them just a few minutes ago with a tally of the damage.
Draw your own conclusions on where you want to have your BMW serviced.
PS - On researching a worst-case scenario (and also because I have multiple PhDs in bullshit detection), the BMW microfiche shows the final drive being bolted together with ordinary torx bolts.
