    Can someone give me an explanation of why this has happened, becus I know nothing about engines

    I've had my car for a year, and whenever I hit over 4k rev's it would go into limp mode (everytime), as tho it had been red lined

    Did an airport Run today (snakes pass) and on the way back, i gave it a little welly, and it kicked a little smoke out. Since doing that (which I dont do often) Its now able to red line at 7k rev, it feels great, nice and roar-ey. Can anyone with knowledge of cars explained what may have happened?

    Cheers guys
    Luke

    ADD: I got it serviced 5 months ago

    You ever scan it before to see if the car put any fault codes up etc?

    yeah, i posted them on here back in may: these are them, don't laugh!!

    p1570 Engine control module

    P1137 System too rich Bank 1

    p1297 turbocharger to throttle value

    p0102 Mass air flow circuit

    01314 Engine Control UNit

    I bet the next thing to do is, to check the fault codes on the car?

    Have you cleared the fault codes and have any come back? If not, best start investigating them.
