Need help. At 50K, I went to the dealer and did an oil change. My service computer was reset and I was told that I have another 15K before the next service. My buddy and I recently did a tune-up which included oil change, irridium spark plugs, fuel filter oil filter, and ac micro filter. My questions are: What would the dealer had done in addition to what we did when we go in at the 15K count down? and If there is nothing else to do, how do you reset the count down computer. If it matters, the car is a 328I.
