My throttle is a tiny bit squishier than normal, the sound isn't quite the same, and I started to get the little shudder when I start the car from time to time that normally isn't there. Who knows, I may also need coil packs or something else. No check engine lights or warnings, and no loss of actual power, but I agree that 18k when you daily this car may be too long. 15k is probably the sweet spot for a stock motor.

Thanks for sharing!

At what mileage does BMW recommend the spark plugs be changed? 15000 miles seems really low.
