Dam i just had the same problem with the XH UTE today. Wouldnt start in Park, some diagnostic crap came up on the dash. Thought it musnt have been in park but it was so i took it out of park and back in, tried to start it but it was the same! Wacked her in nutral, it starts. Drove off, stoped at the next delivery. When i went to start it again, Same :( Put it in nutral, started. Got back to HQ, stopped put it in park, tried to start, wouldnt start. Nutural, started. Turned engine off put it in park and it started!! I dont know how it works but i suspect theres a dodgy switch under the Gear leaver somewhere. Anyone else have any idea? It the work car so im not too fussed, the boss can pay for it if its somthin major.
