If i drove gently all the time i wouldnt even notice, as once the car has warmed up it only really plays up when you accelerate quickly, although it is also hard to pull away smoothly sometimes when the engine is cold and revs are low. All I'm saying is the contactless repair itself is probably fine but my ETM is now causing a hestitatation and lumpyness now and again, so there is something else wrong with my ETM or the current software is having a problem with the repaired ETM? I'm 99 percent sure a new ETM and new software will fix mine, although as i said i will not do this until it gets worse as i can live with it at the moment, there are no error codes, and its not that bad. It might never get worse and i can live with it as-is. As i said in the early post, my car can run everyday for a week spot on, then it might run lumpy for a few seconds a couple of time the following week, so it is occasional.
Prehaps we have the same fault? I will watch this thread with interest to see what the outcome is.
