The car is perfect except for a reoccuring problem.
Without warning, and for no apparent reason, the ESP light comes on and this is usually followed with engine malfunction and the car going into limp home mode.
It has happened about 7 or 8 times in about 3,000 miles and I have had a diagnostics which reveals U0001 (High speed CAN loss communication BUS) and U0415 (invalid data received from ABS)
The fault has occured 3 times at the same roundabout (which is strange) and only appears to happen at night (which is stranger)
The fault also has varying degrees of severity - sometimes the ESP light comes on and stays on and thats it - sometimes the ESP light is followed by the engine malfunction and going into limp home mode - sometimes the ESP light is followed by engine malfunction AND every light is flashing and every warning noise is bleeping and bonging and the car will only tick over - sometimes the EML is left on and other times nothing. The fault resets after turning the car off for a minute and restarting.
Anybody with any ideas or experienced a similar faulty
Phil
PS - On a cold morning or a cold evening after standing the car is a bit hard and lumpy at start up - it's fine after that - thought I'd mention it.
This is quite stunning Phil; apart from the roundabout issue, this is exactly what's happening to my Ford Galaxy so I guess it's a Ford glitch. I've taken the problem to two local garages who've stuck the diagnostic tool on and have shrugged their shoulders, just suggesting a fuel filter issue, so I've had the filter changed twice. OK, there are minor differences. I can drive for 50 miles, keeping the revs under 2K and nothing happens, then overtake an even slower vehicle (Ford with same issue?) and the ESP light comes on, the car slowing quite violently, Some times the engine warning triangle comes on as well. I pull over, wait a minute and all's well. Prior to reading your issue, I was about to phone an expensive garage in desperation, knowing I'd spend a few hundred quid, and be told that in spite of the bill, there's nothing to be done, or spun a story. I've been through the replies to your original post and either I'm not up to some of the fixes, or I'm not confident they're similar enough, If you do discover what the issue is I'd kiss your feet as, like you I love my car but for this one scary fault.
Good luck to us both
