[amjad hussain]

else hi there im trying to work out my horrific problem i was driving on motorway  down to London and at 70 mph my car just cut off ...  just before it cut off i had the eml light come on and moment after it suddenly cut off it locked up my brakes and i nearly crashed any way after this even i had a recovery team come out to to inspect the car and they checked it out but they said it wasn't giving any codes and they couldn't diagnose why it had randomly cut out they said it could have been a ecu glitch.... after this event the car still starts it hasn't had a seized engine or anything but it was quite random is there any one else  who has had a similar problem ..... 

 

im not driving this car on motor way
