Apparently YMMV, with is too bad.
Supposedly, There is only one tech at my dealer who qualified/experienced enough to do the work (or so they tell me). I did talk to the tech who did the work and he did say the install was a bit of a pain, so I am wondering if people's issues are the result of a somewhat botched install.
In any event, I am happy with the choice and I made sure that my tech got a bottle of scotch for his patience and work (which, I might add, as purchased some good will going forward
That's interesting. Did you happen to ask or hear what was "a bit of a pain" to install from your tech?
Did you ask the tech if the install procedure has a TSB issued for it? It would be great to read it if it exists. I would expect that BMW will, should have, issued the TSB install procedure if it's that involved.
That way the people who have issues with their M Perf brakes can ask if their dealer has this information.
