There are a lot of 1.8 T on the road in all v.a.g vehicles and only a small % fail and it doesn't seem to mater what oil they were using.Fuel grade may be the answer as the Americans have a lot of issues with sludging and they tried legal action against V.A.G.
You can check the oil pressure in dash insert via vag com in measured value 1 or 3 i cant recall but i will have a look.
If the red warning can comes on then stop the engine and recover to workshop.I clean mine out every year and there is always a bit of munk in there so i don't have the answer but i do have the repair and advise of the worst case of damage it can cause.
As i said don't let it put you off as 1.8 T is a good engine and very strong,i service my mates and he has never had the issue and that's on 190,000 miles so what is that telling us.Great question syboit hope i make some sense and hope some one gives me the source of the issue
