engine management light on above 160mph @9k in 6th
 

Also when i giving it some large portions yesterday in top gear, when it reached about 9k and approx 160mph the engine mangement light came on??
i shut off to just below this and it went out, nailed and it comes on. Only in top gear???
:puzzled: no funny sounds, or change in temp!?1

I'd take it back to the shop matey - 174 and then it doesn't show any faster and eng management light on at 160.......sounds like you have a lemon there...?!?!?:devil:

Jeez - I jest...I wouldn't get anywhere near that with a sail up and the wind behind me.:D
