Oil pressure lights (or I should say the occurance there of..) are a fairly 
common problem in our VW's. (Sad to say) My very first problem with my Scirocco 
when I first got it was the oil pressure light comming on at a certain RPM. At 
the time I was oil illiterate and used what dad used, 10-W-40. Come to find out, 
thats for colder climates and its much too thin for my car. So, I learned about 
oils and what it is they do and discovered 20-W-50 to the the hot ticket for my 
car. (all that viscosity stuff and all) It did help stop some of the buzer noize 
for my car. The oil pressure was within specs, new pressure switches, new 
connectors, new oil pump, everything new. Still, I would get the buzz from time 
to time. Lucky for me, the 1.7L spun a bearing (Not bad for a cheaply rebuilt 
motor, 2+ years and 30,000 miles and driven hard!) and I opted for the 1.8L JH 
upgrade. I've not had a single buzzer since swapping to the new motor. Now that 
I have a permanent oil pressure gauge in the car, at idle I have 20lbs and 
driving I have 60+lbs pressure using 15W50 synthetic. 
So, the point is, in my case, the engine was likely the problem for the buzzing 
oil pressure light comming on. Once you've replaced everything related to the 
oil system, there is only one thing left to change. 
HTH!
