I have an issue with my 1.9cdti 150.

The other day I was coming home and after about 1hrs drive pulled in at some shops, when I came to restart engine kept idling very roughly and it cut out a few times.

I have noticed a few times that the idling has been uneven.

So I got home left car for about hour then started it up and idle was again uneven. So I thought I'd record the swirl bar during the event as I don't think it is the EGR and I cleaned this the other day and EGR has been replaced not so long ago.


Any ideas what is causing this? Swirl Valves? EGR? Boost Sensor? some other sensor? No engine management light or spanner light.

I have tried it with EGR disconnected and still the same problem.

Any ideas what could be causing this?
