New van? That's a bit excessive, when only the engine is faulty.

Saltdog this is terrible news and I truly feel for ya. Have a good read on the T5-life forum as this issue is known and very common in the UK and Europe.

The fault, as someone else has explained, lies in the EGR breaking down internally and letting small aluminium particles get into the combustion chamber and scoring the bores therefore allowing the engine oil to pass through and be burnt.

Did you notice if the van was actually driving better at any point?

I too have the same model van with a pre suffix EGR cooler and have taken the first steps of monitoring my oil by 1. changing it at 10,000kms intervals and 2. testing the oil at 5,000kms intervals.
First oil test so far has shown unusual signs of wear but it's only the first test on 10,000km old oil at 139,000kms. Next test is due in about 2,500kms without an oil change then again at 150,000kms to establish a wear trend.
I also had a compression test done at approx 135,00kms with the results all being in the normal range.

What are the options if this proactive testing finds something?

In Markee's case, if there is an extremely high Aluminium reading at the 5000km mark via testing, he can change the oil knowing that the next 5000km he isn't damaging the bores as much by not knowing the aluminium is scoring the bores.

Mine, is merely a safe guard to see what is happening to my engine as its new, and if this issue comes up, i have some data if i have to get goodwill from VW.

Yup what Bryn said and I'll also be 'mapping' out/blocking the EGR and removing the DPF for good measure

I have this now. 2011 TDI400 4 motion. Using roughly 1l of oil per 500kms. And losing coolant too... Fml. I hope the 2nd hand car warranty covers this...
