Judder at 2k revs

**scottymf** · 26th January 2008, 14:26

Any ideas at what this is?

Signum 1.9 CDTI 120

I have what feels like a slight misfire but only at 2k revs.

It will only do it when I drive at an easy cruise, not a thing if I drive it hard.

At happens only when it warm.

A rolling road would probably show it up but before that has anyone got any ideas.!

it judder only when warm engine, and when easy cruise around 1900-2400 rpm

Hi

It doesnt sound like the DMF gladly.

But it does sound like dinac_cro's answer.
Its not doing it in 1st but I dont realy cruise in 1st to notice it anyway.
And it doesnt do it when its cold.

On reading other posts I have noticed that Swirl Bar thing is just floating around doing jack!. Could that be part or all of the problem.

Ive only had the car 2 weeks the garage I got the car from only gave a 1 month warrinty. Would this be covered, or will they just sherk blame.

i replaced swirl bar

i think that is because EGR valve .... go on Tech 2 and see if you have got P0400 error....I have it..

99% it is bad EGR
if you replace it - please write here if that helped

id be looking at the software ,,,judder do you mean more like a flat spot in the revs ,,feels a bit like a misfire

Ill have a go at just putting the swirl bar back on tomoz,

I'm supprised its not that bad without the swirl bar on. Ive read many posts that state their cars drive like a tractor when its not on, I dont even get any faults displaying.

chrisgettings; Its not so much a dead spot just a very slight twitch, you can hardly notice it because of our crappy we pay a fortune for roads.

Dont suppose anyone knows weather the garage i bought it from have a legal obligation to repair or get it repaired?

I read on another post that only the 1.9 150 CDTI and some 2.0 and 2.2's have the swirl bar thing.
Mine is according to the log book is a 120.

Can anyone shed some light attached is my engine with the cover off.

?? For some reason my service reports say its a 150 and all the engine numbers check out and its HPI checked.
