Well it has started up this morning and I've driven it to work, although what damage it was doing im not sure. The power steering warning light is still on and it's making a horrible grinding noise when anywhere close to full lock, even worse in reverse making it close to impossible to park.
Phoned Clemo and they've said to go over and they'll have a listen to see if it is doing too much damage to keep driving it, but they wouldn't be able to sort it until end of the 1st week in March
God knows what the issue with the ignition was and why the climate control was going barmy. 22 months of no problems and then it all comes at once
