Hi, I have a 2002 bi-fuel car with 200k miles on the clock. I wonder if anyone has come across these faults; the interior lights don't work, the door open warning light stays on, the clock and trip mileage reset to zero everytime the car is locked. Occasionally the lpg fuel tank drops to empty and the car switches over to petrol. Any advice would be greatly appreciated. Thanks.

 

I have a 2001 petrol V40 with 145K mileage and I have EXACTLY the same problem! All 3 symptoms the same! No idea where to start, car still drives OK. I have had to replace the headlamp bulb a couple of times in the last month.

 

Is there a common factor I wonder: the switch in the door (apparently inaccessible and expensive to replace) which controls the interior lights?
