CLS320 Juddering!! Please Help

[Caribe]

Good Afternoon

My 2006 CLS320 has a judder at around 1200 rpm on really gentle acceleration when its cold.

It goes away once the car is warm.

I can replicate it when it is sitting in park or neutral as well by just revving it. It feels like a vibration (no weird noises)

Once car is up to temp it goes away....

I have had the box oil replaced around 1500 miles ago and it was on the STAR system as well. Only other fault was 02 sensor needing replaced again.

Any ideas at all? Weird that it goes away once its warm.

Worn engine mounts?

its really frustrating not knowing what it could be.

I thought it was perhaps a blocked fuel filter, but it definitely clears when the car is driven for about 10 - 15 minutes and up to full temperature.

It feels like a mis fire as its juddering.

Any one?

As per Olly's post. Worn Engine Mounts.

Had it to garage and its not the mounts.

They think that it is a fuelling issue. There is unburnt diesel being blasted out the back on heavy throttle.

Its worse when its cold as well.

Ran some fortec cleaner through it but it was still doing it this morning.

So its going back into the garage and it will be hooked up to STAR to see if anything is showing now. Last time it was on the 02 sensor was showing to need replaced....

Would the 02 sensor cause this though?

So its the turbo
