Hi everyone. Just wanted to inform everyone of the issues that I'm currently dealing with, and others around the globe are also having.
I own a 2010 T5.1 Tarnsporter 4motion LWB, BiTurbo. Has been losing oil for about a year now.
And I'm talking serious oil - prob put 30-40 litres oil over that time!
VW dealer cannot find source of this loss and I have commenced a 1000km oil consumption test.
The dealer basically said that if it uses more than 0.5 Litres per 1000km, then a new engine is required!
Am out of warranty, the vans only done 135,000km. Not sure if VW Australia would cover this cost.

It seems to be happening to models from 2010 on.

The fault - Piston ring failure I think...

VW have issued a TPI number 2039830/5
In summary the TPI says;
Excessive oil consumption = worn cylinder walls = Replace base Engine, Cat, DPF, Lambda probe, new software.

Will update results of my consumption test, and outcome of any dealings with VW.

Cheers
