[Vwdiesel] Is it weird oil pressure?

Does it also happen if you burn up a hill in 4th, then at the top drop it into
5th and let it coast down to around 2000rpm? If so, then you've got what I
had, or similar - low hot oil pressure caused by failed int. shaft bearings. If
it only happens when cornering, then it sounds like you need some better
baffling in the oilpan. But I never got this when cornering, and there are
plenty of curvy roads around here...
You need to install a gauge, preferably mechanical to see what's going on.
