oil pressure light comes on at high speed

Too much oil in crank case at high speed would cause high oil pressure activating your oil pressure light, check your oil level. Could also be a faulty oil pressure sensor works fine at idle speeds but once oil pressure builds up it may stop working, there are two sensors usually on the vdubs low and high pressure change both of them their are cheap to buy and easy to replace.

THANKS I THINK YOU COULD BE RIGHT IV ALSO HEARD THAT IT COULD BE A BUILD UP OF GUNK IN THE SUMP AND THAT THEIR IS A FILTER THAT IS CLOGGING UP

After reading that I have to ask....when was the last time you changed your oil? kms/miles?
