I don't know how the regeneration system works, unfortunately, but I wonder if the diesel feed to the regen at idle is still letting in diesel, hence knowing the smell may help.
You should be able to read up in Vida how the regen system works, I cannot do that on my Vida as my car doesn't have it, I think it uses the serial number to list the info from the manual, somebody else may be able to confirm I'm wrong.
Are there not any other codes listed?

Yes there is an oil smell from the Exhaust no a diesel smell on idol - also when hot after driving and settling at lights to an idol there is smoke on acceleration - a lot...

The colour of this smoke is oily blue.

Going to test drive later and check turbo pressures followed by visual inspection on the induction piping to the turbo to look for oil. If I can identify that the Turbo is faulty then great.

I have a huge journey in 2 weeks time so I don't want the car breaking down.
