e30 temp sensor?

[evandael]

besides verifying continuity in the wiring, checking the gauge itself, and making sure the sensor isn't kaput.. did you install the e30 brown-top temp sender in the s50 head?

[bmwdready347]

No,e30 temp señor every thing is stock from the s50

[bmwdready347]

And is it the sensor in the back I have to change on the head or is it the first one close to the front of the head

[evandael]

Fairly certain it is the rearmost sensor that should be replaced with the e30 brown-top.

the one in the rear. change to e30 brown

thankas does any one have part number

black sensor runs the ecu - keep this one to run the ecu.
blue one runs the e36 gauge - change this one to the brown e30 gauge sensor.

None of us have the pn memorized. Luckily, it's easy to look up: http://www.realoem.com
