Hi can you help? P reg 3000tdi discovery my key light symble keep coming on & off when driving, may go a while say a few miles then on & off every 20 secons or so, only done it since it was stud for a few months and the battery went flat, put a new battery on started perfect as normal truck runs like new. It had a new key fob 6 months ago but been ok when that was done, driving me nuts trying to work it out.
