What's wrong with my 2007 Skoda Octavia?

Hello,

I have a 2007 Skoda Octavia 2007 1.9 TDI that sometimes won't start - the engine will turn over, but won't start. When it does eventually start it runs ok for a while, then it cuts out and won't start any more: fuel pump, pipes, filter and fuses etc, have been checked and all ok. Have a fault code but not sure if related - P1650 data bus powertrain: missing message from instrument cluster ECU.

Thanks

Steve

Hi Steve,

That fault code indicates a wiring issue somewhere that may well be your problem, but would require a good auto electrician to sort out. 

However, before doing that, a known issue with that car causing similar problems is a faulty engine coolant temperature sensor that intermittently sends the wrong signal to the car's brain and causes all kinds of problems. It needs to be replaced and shouldn't cost the earth.
