Difficult to accelerate past 3000rpm
« on: May 29, 2015, 08:04:58 pm »
Was accelerating the car on the motorway from 20mph to 100mph but as soon as I hit 100mph I lost all power and the was decelerating for about 1min until the power of accelerating came back.

Replicated the issue, and each time for about 50seconds I would get the power back, so when it lost power going past 100mph, if I kept my foot down on it for 50seconds after it losing power it would all of sudden come back and then happen again once going past 100mph.

Now I'm unable to really accelerate, can get upto 60mph or whatever but it takes an age.

Scanned the car:

Cam follower was changed a month or 2 ago those errors look similar to ones I've seen with a worn cam follower.

Even when I changed the old one it was in great condition.

Is that the sensor on the High Pressure Pump on the cylinder head or in the tank?

Seen that but they don't have any issues accelerating, it's as if it was in a sort of limp mode, extremely powerless. Cleared the faults and filled up with some petrol and did a few runs upto about 120mph and drove like a dream, couldnt exactly replica my driving earlier today as I was driving for about 2 hours but noticed it happened to me earlier today when going from 60-100 in 6th gear. Strange it now has full power after putting in some petrol and clearing the fault.
