Don't think it's related to the software issues, but left work Friday and keyfob wouldn't unlock car. Used the mechanical key to unlock and get in(alarm went off for about 5 seconds!), thought it was just a duff keyfob battery problem. Changed battery and it still wouldn't lock/unlock, tried spare key and that worked fine so assumed fob was faulty. However spare key is only working intermittently now as well (Sunday). Car booked in monday to be looked at. 😞
