I took my 2006 X Type Estate in for its MOT which went well but when i came to start it I noticed the Navigation screen was blank. I contacted the garage and the mechanics said it was blank when they did the MOT. The garage does'nt have a clue whats happened To be fair to the Garage we had the AirCon compressor changed by a different garage in February and after that it did the same only the mechanic said it happens a lot, Just chill and it will dry out (Got damp I presume) It did come back. This new problem has got them beat. <any help out there would be appreciated.
The other issueis to do with engine management. When i need to overtake and put my foot down the car will slow down and loose power and a coil symbol comes up on the dash. I stop and restart and its back to normal until the next time.
