Self diagnosing cause of "VPC unavailable"
My car ('06 2.4JTDm) has just started showing the warning sign that indicates steering wheel lock failure, with the message on startup and shutdown that "Vehicle Protection System is Unavailable".
From searching the forums it seems that people have found various causes for this error; battery, key fob, connections behind the key slot, faulty steering column lock etc.
Most people have suggested taking back to the dealers to sort out, but mine is out of warranty and I am absolutely skint at the moment! How much of the diagnosing could I do myself, and could anyone give me some directions or tips? I'm not much of a DIY mechanic, but I am willing to learn! Please also advise if you think having a go myself is unwise given the amount that I don't know!
