Finally managed to get connected after months of half hearted attempts. Managed to connect through android phone with OBDlink LX hardware and AlfaOBD software. Very happy as I made the time after taking a trip out into the middle of nowhere and having engine light come on after overly enthusiastic driving in the heat. Error code was due to overboost. AlfaOBD allowed me to read error with description and clear option. Running full diagnostic after shows an overboost count of 124 and knock sensor reading of 45. Is this high in relativity of a 73000km mileage? Also can one clear these counts without going to dealer? Would like to keep track from a reset.
