FWIW, I drove a '94 E420 to 300,000 miles and had to replace the oil pressure sending unit 3 times. The first time it did it, it scared the... well, I was SHOOK!

I was driving down the interstate and noticed that the gauge wasn't pegged. Ten miles later it was almost on zero after jumping around erratically. A local independant mechanic actually made a fitting adapter with a tap and die set so that he could hook up a manual guage and confirm good oil pressure. I drove the 100 miles home and had the sender replaced the next day.

A varient of this scene happened twice more (without the panic) while I owned the car. Iwould suggest, however, that you address this ASAP. If it is not the sending unit, continuing to drive the car can only add to the problem.

Best Regards,
