on the way home from the shops tonight the car seemed to loose power. It happened when I came onto the city by pass, I was going up through the gears, 3rd-4th was fine, 4th-5th had a slight flat spot then 5th-6th was a complete loss of power to the point where I had to nurse the car back home. When it happened there was no warning light on the dash and also no smoke was apparent out the rear view mirror.
The car is a 2.0 TDI BRE and has been remapped by Quantum.
Has anyone any ideas as to what could be the issue?
