engine stutter

Hi guys

Just hoping someone can give me a few pointers on where to look.
Basically our td4 BMW lump stutters/hesitates at slow speed, noticeable in 3rd gear cruising at 30mph.
I have added in some of that fuel cleaning additive in the hope something was blocked but to no avail.
My only slight concern is that I fitted a fuel injector pump a few months ago and just worried it's that, though there's no leaks like before.
Acceleration is fine.

Any ideas?
Thanks a lot

We got a local garage to hook up the diagnostic computer today but no faults were found.....any ideas guys?

Have you cleaned the EGR valve? when was the last time you cleaned or replaced the crankcase filter. Mike

Hi Mike,

Thanks for the reply, I didn't get a notification anyone replied hence the late response.
I've changed the egr valve for the modification and the crankcase filter also for the BMW mod

No problem, keep us informed as to whether it helps or not. Mike

I wonder just how many TD4s suffer this problem but the respective owner descriptions varying the true story somewhat.
Sounds like TD4 2K syndrome to me.
