2003 XJR V6 (X350) ELETRONIC ISSUE

[Flightengineer]

This is one for the tech's. I think that I'm very tech savvy however this one has me stumped, I hope someone else has had this issue.

This intermittent fault starts with the wiper's moving very slow when not switched on the car throws just about every warning on the dash, then

if you turn the wiper's on the engine stop's. I can't find any common denominator as to to when or why this happens. HELP!!!
