I’ve started getting lumpy running like a misfire upon startup and until warm most times i start up including warm and cold starts.

No faults showing on dash or iidtool

Initially I’m thinking could be EGR so ran around with live values for a bit and note the % fluctuates but not sure if that’s normal or not. Left and right are not showing same value all the time.

I’ve read possibly a glow plug but not sure how that can be as it starts up fine.

The problem is mild in neutral and shows more when in gear.

Any ideas?

Thanks __

Also, problem disappears under hard acceleration... but is pronounced under idle and very light throttle. __

Hate to say it, but that sounds like some unhappy injectors... But I could still be suffering from Roverphobia  Yesterday I couldn't spell Engineer... Today I are one!

Sound like an injector fault to me.

Have you had a look at the live values or done a leak off test?

I'll get it booked into a specialist then!

It's intermittent which is why i didn't initially think injectors. Today for example it ran perfectly well. __

My TD6 had I very occasional lumpy tick over which gradually got worse to the point it was doing it all the time.

Turned out to be an injector fault.

If your car is reasonably low mileage then you could try some injector cleaner, but if it's anywhere neer 100k +/- 20k then I'd suspect the injectors could do with a deep clean and testing on a test rig. If you're not doing the removal yourself then I'd suggest either a trusted indy, or a Bosch Service Centre..... 2 reasons for this, you'll save on the labor and importantly the Stealers will not fit recon injectors, they'll just replace with new and charge you the equivalent of a full clean and test by the diesel specialist per injector...... so if you want to pay up to 8x too much you know where to take it  Yesterday I couldn't spell Engineer...

Don’t be too hasty removing the injectors either as the seals and pipes need replacing each time they are removed and that adds up too!!! £100 ish each cylinder springs to mind, but it has been some time since we last did some...

Specialist found 3 injectors well out of tolerance and are changing them as I type. __
