Oil pressure sensors

VW Part number 021-919-081BH

Try to get a German one (although they're getting hard to find)

Bugcity.com has them in stock, Aircooled.net has a Brazilian(?) version, CIP1 does not have them in stock.

CB Performance has them as VDO at $44.  OEM VDO units are very good.  Avoid senders under $30 as they're junk and tend to leak after a short time.

Yeah, I think Tom here wants the VDO dual sensor, it has a variable output terminal for the gauge and another terminal for the idiot light.

The answer to which VDO sender is needed depends on the range of the gauge. VDO has a good website, you should be able to find what you need. Thread size of VW oil port is 10mm x 1.0.

Just to ask , is there a USA or Japanese sensor that does the same thing,

I assume it changes the resistance  depending what the oil pressure is ,  

Do all VDO oil pressure  gauges use the same sensor ?

I know the idiot light oil pressure switch has a number stamped on the side to tell the pressure it turns on the light.

There's a Brazilian Youtuber called Marcello Tonella who's a very experienced aircooled VW mechanic and he swears by a Brazilian brand called Intermec for the oil pressure sensor.
