2.2 diesel. Cold start very lumpy

[Greg]

My wife's X Type 2.2 diesel has severe lumpiness starting from cold. It's so lumpy the car surges forward violently like a heart beat.

The Shropshire Jag main agent misdiagnosed changing the EGR valve, still lumpy. They suggest cleaning the injectors,  why?  Car runs perfect when just above cold.

I think it could be the Mass Air Flow Sensor. Any suggestion what the fault could be? 

Thanks in advance

Having had a Mondeo tdci, and a family member currently with a Transit tdci, I would concur with the suggestion of cleaning the injectors. 

I highly recommend Millars Sport 4 diesel injector cleaner, when used in the Mondeo which always started on 3 cylnders and run rough when cold, it transformed it - cold starting roughness disappeared, and even hot running was quieter and smoother. We tried it recently on the Transit to the same effect, so the stuff still works.

Thanks for that info. The injectors were cleaned with a similar product but I will give Millars a go

Hi Greg,

I have a similar issue with my 2.2d auto - EGR is okay.

Did you sort the problem with your wife's Jag? If so what was it?

Thanks,

Simon
