Driving along at low speed, when I noticed a brief flashing of the CEL light, accompanied by some vibration of the car and a knocking type of noise from the car.
I turned the car off, and restarted - the same problem.
Second restart, revved the engine , and again, the same - as the revs fall towards idle, there is a distinct knocking noise from the engine and vibration of the car.
The CEL light is now permanently on. A "Engine Control System Failure" message came up, and then "Go to Dealer".
The engine wont idle without revs and is lumpy like its running on four cylinders - dealer diagnosed the fault as variator valves and repair bill is about £3k
I would like to know how common this fault is as I heard that QP's are virtually unsellable without this being done usually advertised as "cam caps replaced" or similar
