Personally I prefer the dynamic oil pressure warning system over a gauge. Having a buzzer go off with low oil pressure at cruise is a really good idea. A gauge is only useful when someone is looking at it.
From Mk2 onward the various VWs have been fitted with the dynamic oil pressure warning system which has two senders, one which registers oil pressure at idle and one above 2,000 rpms.

Are you sure this is mk2's only? I have a two sensor system and my car is an 84... Just wondering is it not a dynamic system? Just buzzing and sound for both high and low on 84s?

Because of that, the oil pressure is higher when cruising than it is at idle. Because most catastrophic failures occur when under power rather than idling, VW decided that it was a good idea to warn the vehicle operator when the oil pressure dropped too low when driving rather than just when idling. The "high pressure" sender does not buzz to indicate that the pressure is too high, it gives the warning when oil pressure is too low when the rpms are above 2,000 rpms.As far as my comment about mk2s, I used that generally rather than specifically. You would have to look at your specific model to see when they transitioned to the dynamic system. That makes about a thousand times more sense. I was very confused about why VW was apparently out of their minds when they designed this system.I was just thinking fuzzy. Thanks for the clarification! Sent from my HTC Mecha using Tapatalk 2
