Here's another pesky indicator. I had a new set of tires installed yesterday by a local retailer (not the BMW dealer). The Michelin Pilot Sports are the correct replacement size - front and rear. No problem encountered this morning but, this afternoon the Flat Tire Monitor indicator light came on. Suspecting that the installation was poor on one tire, I stopped to check the tire pressure. All four were very close to the factory specified air pressure. When I got home, I doubled-checked each tire and added air where needed to bring all the tires up to the specified pressure. Then, I completed the instructions in the owner's manual (page 88) for "Initializing the system". But the indicator light continues to burn. I also tried the "activate/deactivate the system" procedures on page 89 with no effect. So, is there a simple and reliable procedure that will reset the warning system to make that indicator light go out? I really hate to go into the dealer with this if I can help it.
