Vw t6 engine judder/shunt on start up

[K19]

Hi I’ve got a 2017 vw t6 2.0 tdi 150
On start up it has developed a engine shudder/knocking which last only a second or 2 and then engine runs completely fine, it doesn’t matter if the engine is hot or cold it does it every start up (even start/stop) I have checked the basics such as engine mounts etc and all seem fine, the engine don’t move that much but it sounds as though a engine mount is bad and the engine is knocking back and forth, any help would be appreciated, thanks in advance.

Any coolant loss?
If so suspect a leaking EGR cooler or leaking charge air cooler if fitted.

No coolant loss at all

Have you checked for fault codes?

I haven’t yet as I don’t have a code reader, would a code show a EML light etc or not always? Thanks in advance

Not necessarily, Carista is a good tool, available from Amazon.
There’s an annual subscription.
Live Data function would allow you to monitor the fuel pressure and injector performance.

Okay thank you I will get it ordered and see what I find

Just to add - you don't need the annual subscription to read the codes. That is just for if you want to change some of the settings/reset codes etc.

Carista Beta is a test / development mode, has some extras, website explains. I think you need a subscription for that.
Anyway as far as I know you get 30 days free subscription when purchasing, check that’s actually the case before signing up.

Dual mass flywheel?

Dual mass flywheel?

That was my thought too, mine does this, then oil happens, then no more noise. However I’ve got a sachs clutch kit on standby should I need to replace it.
