I know it looks a lot but the fact that the fault has occured 3 times at the same place (Beckingham roundabout at about 40MPH) indicates to me that it's a sensor or wire/connector that is detecting a fault at that certain angle/speed/pressure going around the island and is throwing up the other faults.
Eg - could the throttle sensor faults be due to the car going into limp home mode ?

The car drives great 99% of the time and has only happened about 7 or 8 times now in 4 - 5,000 miles (always at night (with headlights on?))
Any thoughts????
