I’m still bong free since the dealership updated me to 1899 just over 3 weeks ago, once I picked the car up i noticed that some of the coding I’d done had been reset, namely maps in cluster and infotainment simultaneously, i re-coded this when back home, and as I normally would I cleared any fault codes that were present, perhaps I too have been bong free purely due to fault code clearing?!? This also makes me wonder if this is the reason I’ve been virtually bong free regardless of SW version, as I have coded things right from the off, and as such have been periodically fault clearing!
