My 2001 M3 Service Engine Soon light came on during run-of-the-mill spirited driving last week. Not the filler cap (topped off gas tank and double checked) and no strange sounds, power loss, etc. Went out of warranty in June, and a sensor was replaced under warranty during its last visit (June 8th).
Any recommendations on a good independent mechanic near Fairfax/Chantilly to take a look at it? I feel like every time I drive near the dealer I get 200 dollars sucked out of my wallet.
Thanks!
