Hi, I have a 2005 3.0d - it’s been mostly fine but a strange issue has developed.

The fasten seat belt warning has been going off when it isn’t occupied, even with the belt clipped in the warning persists.

The air bag light illuminates

Wipers stop working and occasionally the CD player.

Now it has Trans fail safe warning..

I have checked the boot for water and damp which people have advised - bone dry. What could it be? Thanks
