Bought a '00 330ci with 90k on the clock about a month ago. Took it for a good hoon a few days later only for the engine light to come on. An independent BMW specialist diagnosed the thermostat to be at fault and duly fixed it, replacing the coolant. I took it for another spirited drive last night, lo and behold the light comes back on; I'm guessing air flow sensor, could it be anything else?
