I had to take "Ginger" one of the works vans to the garage to get a check up.
It's been showing two engine warning lights on the dash for the last two weeks.
When I picked it up at 5pm, I was told that NO warning lights were showing when they took it into the workshop and couldn't find anything wrong??
The mechanic also said that "fault needs to be present before diagnosis can be made!!".
Oh well! it seems to be running fine and no charge.
