Temp gauge??

[Blackie_No1]

Ok im baffled, i managed to geet the clock and inspection lamps turned off on my SI board, have changed the temp sender unit(the one on mine is a black two pin jobby as the engine came from a 525) earthed one pin of the sender plug out to find gauge needle does rise, but yet the gauge dont work, cud it be this gizmo at the bottom of the clocks??


Sorry bout pic quality, i had the clocks out to fit chrome rings to the dials, inspected the batteries which seem in good order, no corrosion or leaks, but still the gauge dont work!!


HEEEEEEEEELLLLLLLLLLLLLLLPPPPPPPPPP!!!!!!!!!!!!!

525 M50 ? Change the temp sensor for a brown single pin M20 one.
White plug in thing is the coding plug - mainly to tell the dials whether your car is 4 cylinder or a proper 6 cylinder one. Wouldn't affect temp gauge.

nah she is a 525 m20 engine, same as found in the 325, did think about putting in the brown plug, but is a different size, i would have to change the whole thermostat housing to fit the brwon plug.

When i was gettin the new temp sender from BMW they said that it should still work as it is the same engine bar a few small difference's
