In Reply to: Phil, the loose bolts issue is on the v8s. Adnan posted by Bill R. on November 27, 2000 at 11:45:16:

only has the low pressure on initial startup when cold, which makes me think it either a viscosity problem or the filter is draining down overnight. It doesnt sound like a low pressure while running problem like a worn pump, bearings etc. Or a faulty sensor which would indicate at times other than initial startup. Just my $.02

BMW pumps are pretty sturdy...but I have read reports of loose pump bolts. However, Eric is right..if you don't mind spending the money AND you want peace of mind, have the tech check the pressure!

Good luck...
