Went for a drive on sunday and filled up with fuel, shortly after i booted it off a roundabout and the engine management light and the red warning light came on, the car sounded fine but on 4000+ rpm it would missfire and hold back so i pulled over and turned the car off and then it would not start. I had a mechanic check it over and he said it had spark and fuel but when you turn the key it would crank over but not even try to fire up and theres a sort of knocking noise from the boot area that i dont normally hear. So i had the car recovered back home where its sitting in the garage
