Well I haven't yet! One of my local Indys put their fault code reader on it and again its showing the same fault. First thing he wants to check is the tracking...........another £50 or there abouts and I can not believe it could be the cause so declined their services. Went down the second hand route, got a guy in Luton, not exactly local, he will fit a S/H unit and sync it for £250, says if it does not work, no charge. Still unsure what to do, MOT is not for another 8 months so no rush!
