I own a Ford Focus CC3 2008 2.0 tdci and for a while now have been experiencing engine malfunction on dash. Recently had fuel filter changed twice, fuel volume valve replaced, egr cleaned and dpf replaced, the message is still coming up. Now it's not showing any fault codes and seems to only come on when the car has warmed up and when idle, drives fine and the message will sometimes go out but once I stop it beeps at me again. I have also changed the air filter. Took it to a diesel specialist and they say nothing showing up when they stick it on the computer, I asked if I should take it to Ford but he said they use their software. Also if I put my foot down the esp light comes and stays on.

Any ideas what this might be?

Appreciate any feedback

Thanks

Engine malfunction doesn't have to be an engine problem (I know that sounds daft lol!). Mine came up for an electrical CAN communications error.

I'd be very surprised if the diesel specialist used Ford equipment unless they are also a Ford specialist. Personally I would have the codes read at Ford. Or have the live data feed checked at idle to see exactly what is happening when the fault is coming on. This can also be done with FORScan if you know anyone with it.

Also, do you know about test mode on the dash clocks? You can find DTC's (data trouble codes) yourself quickly and easily and free.

Thanks for responding, I have done the self diagnostic but no DTC codes came up, I don't really want to pay Ford for them to tell me the same thing, no OBD code so nothing wrong, however the communication error might be something, I remember something being written down but have lost the bit of paper it was something communication bus... Will have to look it up on line.

Hi Kylie,

Did you ever resolve your Engine Malfunction issue? I have similar problems!

Thanks

I did get it sorted, something to do with the fuel pump, had the volume valve changed but there was still a fault, got it fixed very expensive repair, I later found out the mechanic I went to was not recommended, so do your research, difficulty I had was not many diesel specialists near me and I wasn't willing to pay Ford to take a look.

I got rid of the car afterwards, as car had constant problems.
