Dual mass flywheel perhaps? If it's badly worn it can give a lot of 'play' between engine and gearbox. Mine used to be a little like you described before I replaced it.
Might also be worth finding a Nanocom and check that the throttle pedal is performing as it should. |

I had a very similar issue, I think it's a bit of clutch/DMF shudder. Mine was worse with a heavily laden trailer. new DMF made it a lot better, though not fully eliminated.
My clutch is due for replacement, so that might make it better again. Generally I find that the engine is much happier above 1500RPM than lugging around on idle. While it is a torquey diesel, the TD5's in general seem to thrive on revs way more than the older engines. |

As above, I ditched the DMF and went for a SMF from LOF and the car drives much nicer. No judder, it just feels like the engine and gearbox are now 'connected'.

That might indeed be the case... The car is stalling quite easily when doing a steep uphill start (no it's not the driver lol) - so I need to give it quite a bit of bean and it then feels like the clutch is slipping as result. However, the clutch is fine otherwise, does not seem worn a bit.
If the DMF needed replacing, wouldn't there be some sort of clanging noise? |

No, a failing DMF tends to mimic classic clutch judder (at least on my Disco2 it does).
Your first post suggests that it judders when your foot is nowhere near the clutch pedal, which makes me feel that although a worn DMF may be a factor it is not the cause, the TD5 is usually a very smooth engine (a benefit of 5 cylinders and the resultant crank angles). If the engine is not running as it should, any play or backlash in the transmission, suspension, or engine/gearbox mounts will make the sensation worse and far more unpleasant. |

Do you still have the EGR system fitted? A sticking EGR valve can often cause an apparent lack of torque when pulling away. I only realised it was failing on one of my other vehicles when i noticed I had needed to start using quite a few more revs when pulling away to prevent stalling.
It could cause some jerky running too I guess but not necessarily. Steve 02' 110 TD5 Double Cab Rebuild Thread 84' 90 3.9 V8 Caged Pickup Build Thread - Now For Sale Mobile Diesel Heater Build Thread |

Hi Blackwolf - you are correct the judder would happen when my left foot is off the clutch completely... low rev and bumpy road, my foot on the accelerator and it starts to judder... unless I pull my foot off the gas (or floor it, which is very unpleasant on bumpy roads), the movement amplifies into a full mode Kangaroo. Could it be fueling related? I was planning to take the fuel filter housing and see whether it's in good shape / clean it and put it back. As for the EGR, it is still on. I ordered a bypass kit from AliSport to blank it. If I am brave enough, I might also attempt to remove the inlet manifold and clean any potential (likely!) gunk in there. |

I had dual mass flywheel judder last year between 1500rpm and 1750rpm in normal driving. it would disaapear in the revs above that until i doubled the rpm 3000-3500 and it would come back again like a weird hardmonic. I could also make it do it with the car in neutral and stationary too. Changed for a lof single mass in the end.

Hi landyman - would your flywheel make any noise (clutch on /off in neutral) that indicated a problem besides the judders?

No there was no rattle as others talk about with dual mass, just major shuddering, would shake the whole car. When I came to change it I undid the wading bung on the bottom of the bell housing and there were some nasty fluids in the bottom, some oil etc. May be worth pulling yours out and seeing if anything has leaked onto your clutch and flywheel.

I'm guessing 10P engine Pre 2002 Td5, if so my money would be on accelerator pedal or clutch switch...
Do you get the same symptoms in low range ? |

Supposedly the engine was upgraded a couple of years ago with a 15p… which I haven’t been able to confirm yet. Haven’t looked at the serial number yet - so busy with work.
To answer your question though, the judders only happen before 1500rpm. They are worst when pulling out. They arent noticeable if pulling out at speed As mentioned above - the clutch isn’t really slipping at all. Worth noting that I need to give more beans than normal to start up a hill. Also - I don’t have records showing when the clutch was last changed… and the car shows 170k miles on the clock. Not a single drop of oil under the car (transferbox, gearbox, engine, diffs, etc…) bone dry. I need to give to JLR who are the ones that fitted the new galv chassis less than -8months ago - it’s top notch (which you’d expect when charged over £7k for it) |

Does it happen more often when the motor is cold or the weather outside is cold and damp?
TD5 clutches DMFs seem to suffer from this cold condition when getting more worn. Patrick[/i] |

Hi Patrick,
It does happen both when the engine is cold & warm. Probably a little worse when cold, but no significant difference. |
