Please help with ongoing issue

If you are leaking oil through turbo seal or pistons, down the exhaust then your cat or DPF (if you have one) will block and will cause more running issues.

Does the car run properly with the exhaust disconnected from the turbo?

I do not have the live data figures, nor have I seen them.

I did not pay for the injectors, the warranty company did as the car is still covered.

My issue is that no one has located the source of the issue.

The car is definitely smoking and it is a blue colour (not heavily blue more a blue / grey) and it smells of unburnt fuel.

The bumper above the exhaust is black as well.

The garage I purchased the car from did a service on it and over filled it with oil (they deny doing it)

The car boosts fine and the fault goes when it is up to temperature.

I tried starting it an hour ago and it turned over for a while before firing... something it has never done before. It usually starts immediately.

The new fuel parts (plugs and injectors) were replaced on Friday

DON'T think this one has a DPF (not checked) but I don't have any dpf warning lights on the dash

sounds like leaking valve stem seals, I had this on a car I once owned. Lots of white smoke at start up and then once warm it disappeared. The oils seeps into the cylinders overnight and build up.

So.. update.

It had a blockage on the DPF (didn't know it had one) that was causing build up of pressure which was forcing the egr open at low rpm hence the poor running at 1100 rpm.

Egr was thoroughly cleaned. New software update from Mercedes in Newcastle and a clean of the blockage on the dpf...... no more smoke or rough idle

4-5 garages looked at it and no one checked the DPF?!?! Name and shame every single one of them. That is shocking.

A bunch of enthusiasts on the net should never be able to determine a fault better than "pros" without even ever seeing the car.

I have been very very angry with the garages and how they kept diagnosing different things that never cured it. Well I drove it 300 miles this weekend and no issues at all.

Atleast it's back uo and running

Just diesels in Blaydon diagnosed and fixed the car
