Bad judder when pulling away in first, second or reverse - manual CDTi

PiperUK · 22nd March 2019, 18:05

Evening fellas, my first post in Technical.

I've got a 2000 Connoisseur SE with Driver Intelligence Pack, Green Personal Line interior and split fold rear seat. 1 owner from well to do Pinner until last year, he threw a lot of wedge at the car. It then unfortunately ended up in the bottom end of Walsall which probably undid all the TLC he gave it.

It's dirty as a lady of the night's back end on the inside. Loose trim, the wooden boot floor is bowed - God knows what stuff they were carrying. The rear bumper is scratched to hell.

Apart from that, everything works apart from the mirrors and I need a code for the Symphony.

I paid £560 for her, probably a tad too much but she wasn't advertised as an Connoisseur SE so when I turned up and saw the spec I knew she needed saving from the hell hole she was in.

So first issue. She's juddering like mad when pulling away in first, second or reverse.

First thought is 'clutch' but... The clutch was changed at 85k miles, she's now on 117k. Then again it depends how it's been driven by the residents of Walsall.

So thoughts turn to master cylinder...whats the consensus? Easy to change?

Edit, its difficult to put it into gear sometimes, but strangely it seems worse after a drive when everything is warmer.

Check the lower engine mount first. Mine did that after the mount gave up.

I'm a low clutch wear driver and if I don't give the clutch some work to do once in a while, I get judder. Trick is to deliberately slip the clutch a little to cure the judder.

I just remembered that i forgot to mention that its difficult to get it into gear somtimes, but strangely it seems easier to shift into first or second from a cold start. Once warm, it seems harder.

Interesting point Harry

I have noticed that when it is damp, the clutch sometimes seem to drag a little. When it warms up it is ok. Something to do with the damp getting in the area of the clutch. Also agree it could be the teardrop underneath.

Could also be a gearbox mount - this was an issue on one of mine. However, it might even be the gear selector ring, which was also a recent issue for me! Cheapest option was a replacement second-hand gearbox.

I once had a car like that, I put (with no real proof) it down to the friction material expanding due to moisture, which would dry out as the clutch was used.

It also suggests the clutch is not fully clearing as the pedal is pressed, I wonder if your master cylinder might be worn?

The original MC on my 75 had some wear in the plastic eye, where it hooks onto the pivot at the pedal. That made mine a matter of flooring the pedal to change gear. A new MC made the operation much better.

What you are doing by slipping the clutch Harry is burning off a faint trace of oil mist coming from somewhere inside the bell housing. Normally a minute leak past the gearbox main shaft seal.

Oil on a driven plate will make the clutch judder.---
