Ok I have another question. Since I bought this car from an auction, I took it to a BMW mechanic and asked to check to see if it needed a tune-up, and I told him that the check engine light comes on and off. He put it on the diagnostic machine and it came up with: hot film/ AMM temper sensor. He said that he didn't think anything needed to be done now, just bring it back if the light came on again. And he didn't do a tune-up, should I have one done anyway since I have no history for the car? |
