1.6Hdi Engine Judder

[MichaelDavis]

Can anyone point me in the direction of what causes the whole engine to judder when I start it up? It also judder when I switch it off. It doesn't run on and apart from this engine is running perfect with no leaks from injectors or any dpf issues and very regular oil and filter changes at 6k miles. I have a feeling it could be a mounting but it has done this for 3 years now and my mechanic said all these hdi engines do this - I find it annoying and have been on a process of fixing things as time allows and would like to fix this issue.

It may be a sign of the clutch dmf failing.

check the egr valve . start with the vacuum on it then check that it is opening and closing correctly

Thanks for the information I have a new egr valve to fit anyway as my mechanic said it's sticking/ broke. When it's changed I will let you know if this fixes the judder

As well as the egr valve, its pipework may be blocked and need cleaning out but your mechanic will know this.

New DMF and clutch fitted, new egr fitted, new turbo vac solenoid fitted - engine still judders on startup and when switched off, new engine mount fitted drivers side- other 2 mounts are fine- what on earth causes the engine to shake/shudder?

Any ideas anyone - Paul, Coastline?

I did a search and it seems to be a common thing on some hdi Peugeots without any faults being found. Maybe you might have to live with it since you have not found anything wrong. You could try a dealer as a last resort. Coastline has not been on here for over a month so may not see this topic for quite some time but you could try a message to him. The email alerts do not seem to be working though.

Thanks Paul
