Hiya people, I'm hoping you wonderful people can give me some guidance on this one. I'm trying to hate electrical diag less. I have a citroen c4 cactus 1.6 E-hdi flair, DV6DTED. Piloted manual. Has codes, U2000 Main wake-up request information reception fault. Not characterised. P1717 Gear lever signal fault. Coherence Car will go into reverse with no issues and but when drive is selected computer says no and gearbox fault comes up. I did a relearn on the gearbox which make me perform a series of driving tasks and i thought it had fixed it as it was ok for a week but now it's back the same. I'm not too sure what direction to go with this one. Any direction would be great.
