Excessive juddering at low revs

[Steve1978]

Hi all.

So I have had an issue with the van for a long time now and I’ve learnt to live with it but thought I would make a Sunday morning post.

At low revs the van judders / rumbles. It’s been suggested to me that it could be the engine or gear box mounts.

It’s not a massive pain but it means that I usually have to hold the revs a bit higher than I would like before changing gear can is a 102hp t6 with a slight remap to 150. It’s a 5 speed manual.

It sounds like it could be your clutch/flywheel? Remaps on the 102 need to be lower torque for the 5 speed box. Did it do it before the map?

To be honest I don’t recall. It’s been about 4 years and at least 50k miles. It only seems to happen in 4th and 5th and only at about 1500-2000 rpm.

It was a modest remap with the 5 speed in mind. Hence about 150hp
