I hope someone can help. I have a 2017 Fiat Fullback. I realise this is a forum for the L200 but there are so few members on the Fiat forum for the Full back so I am hoping you can help .

I have not used 4 wheel drive for some time. While in 2 wheel drive, at 50mph, the diff lock light started flashing, the ABS lights and ESC lights came on. I tried to engage 4 wheel drive while stopped, alternated between forward and reverse but lights would not go out. I think the problem is with the Diff lock sensor. Has anyone else had this problem, and how was it rectified? I have found I can get 4 wheel drive if I switch off select 4 wheel drive, start the engine and reverse, it goes into 4 wheel drive, to get back to 2 wheel drive its the reverse. Bit of a fag when I want to get a load of sheep out of a muddy field.
