It's astonishing how much more people know in the forums than people that work at BMW. I guess that is pretty typical in all of the forums though.
I had my service guy try and tell me that they didn't mess up my RS3, they swore up and down they did just the normal service to it and they "didn't know" how the TPMS light came on and wouldn't go off with the winters on. They even told me I should contact Discount Tire, because it must be their fault. I took the wheels off the car and put them back on and everything was fine.
Just because you work somewhere for 27 years doesn't mean you know everything about the setups that people regularly use.
People come on the forums to have fun, share their experiences, and show off their cars. They don't go on to be hassled "by the man".
