hopefully someone can help my 05 octavia has give up the last few weeks the car has been losing power whilst driving along, the revs just drop and if i press in the clutch they came back again then yesterday it became more persistent until the heater plug light came on an started flashing then the car ran ok until i got a friend to put the computer onto it the engine management light is now on and there's now no acceleration at all  

A N Other for the mod moving? Is it a mk 1 or mk2 octavia?
