I have put my xk8 back on the road for the summer. I alway disconnect the battery when idle for a long time. Charged battery used for a couple of day did about 50 miles no problems. Started car each day after to keep battery charged up no probs. Didn't start for 2 days tried to start car battery flat so jumped tt started no faukts have come up traction contol, gearbox fault cat eon't come out of p and stability contol fault. Any ideas do you think new battery might sort it out when computer re boots. Many Thanks Trev.

 

Short answer, YES
