Why is the 000565 code repeated twice?
Is because there are two engine ECU's - one for each bank or a typo?

07:09:12 G70 got implausible signal @1400rpm
07:09:25 Boost pressure not in range @2800rpm
07:09:41 G246 MAF 2 implausible signal @1134rpm

So on a timeline, the codes are appearing within in a 29 second window.
Hopefully just a boost pipe blew off I would check everything from the turbos' outlets to the inlet manifold.?

Can you get the SSP PDF for the 4.2tdi and identify what G246 and G70 are?
EDIT #59 here...

I didnt see this post on first read through. That does seem like a logical conclusion to reach from the data. Id still have expected loads of smoke and noise from past experience but they are easy things to check so it makes sense to go over the easy stuff first.
