In September on the motorway my 05 2.7 diesel showed restricted performance mode warning but without loss of power, I got to my destination and on return to the car the warning lights were back to normal I had done about 30 miles on the motorway when this occurred. On Friday past I was travelling to Gatwick on the motorway and after about 60 miles the same warning light came on and I lost a lot of power, I managed to get to the hard shoulder and then the car cut out totally, very scary, I also had a message to say about the handbrake was on but it wasn't. After trying to restart 4 or 5 times it restarted and I carried on to Gatwick and back home 180 miles without problem. Got me a bit scared when it happened on the motorway, scared it might happen again, any ideas anyone?
