Reply 23/11/2021. Get your Auto Electrician to check and replace the non conducting paste protecting the connector pins beneath the main fuse box in the engine bay near the battery. I purchased an Xtype AWD 2001 which suffered this problem and the paste had dried out and moisture was apparently causing electric crossing between the pins. This was resolved by removing and replacing this non conductive paste. I had many varied messages on dash screen with erratic dash readings. This vehicle has behaved normally for 4 years since that process.
Good Luck, Alan
