Hello all, I have unfortunately the following problem with my BMW S1000R (17500km) from 2015: In the cold state no problems. As soon as the machine gets warm (about 20min drive) it starts to stutter at constant speed over the complete speed band. It feels as if for the moment one or two cylinders completely shut down. But as soon as I turn up the gas during the stutter, it turns stutter free and with full power into the speed limiter. The fault memory was unfortunately empty. Also the MKL never went on. On good luck I was calibrated by BMW still the gas grip or throttle valve and changed the spark plugs. Unfortunately also without success. My next suspicion would now be the ignition coils. Would the behavior speak for it? In addition, I was told that the air mass meter could be defective. However, I could not find a spare part in the net and some even claim that the S1000R did not have any en hat. I hope for helpful answers and thank you already in advance!
