The oil pressure sender on my '90 W126 420SEL only lasted 2 years. (2 years ago I installed a replacement and just needed to do so again???)

When it goes bad, the symptoms are no oil pressure sometimes and then while driving it will suddenly jump up to 3! Then suddenly go to 0 again.

Replace oil pressure sender, then it works fine again.

I am of course QUITE happy it is just the sender and not the oil pump and not a wiring problem! But I would expect it to last longer than 2 years.

Anyone else have these problems?
