Low oil pressure could cause VANOS (VVT) problems, however $6500 is a very high price to replace the pump. The pump assembly is about $900 and the labor is about 12 hours and need to add oil, filter and oil pan gasket. I don't know what's their labor rate, but based on their estimate it seems to be over $400.... I'd get a second opinion from a BMW specialty shop. Do you happen to have the diagnostic trouble codes?
