Can anyone tell me where the feeds from the three temperature senders on the E28 M5 engine go to - there are blue, brown and brass fixtures on the coolant rail.

One goes to dash temp gauge The others are for ecu. One is inverse resistance the other I recall is a switch for warn up map in the ecu.

Car is elsewhere at present but from memory the rhs one (two spade connectors) is the dash temp gauge. Pull the wires with the engine running and you should loose the dash indication to prove. The other two go to the ecu. Ian |

Yep, Dunc - that's the rail and the senders what I are after talking about. The problem that I have is that someone has been in amongst it with the snips and the reason that I am after this information is that I don't have an operational temperature gauge to disconnect to check for sender status and continuity. Perhaps if you get your car back Ian, you could pull the sender wires off and tell me which one knocks your own gauge out? Appreciated.

Item 9 should have two spade connectors. This should feed the dash temp gauge Ian |

That's the one off the e34 maybe the same for e28 or maybe the cars got an e34 engine... This may be a little off topic but its always good to share - Number 9 should be clear and if its not the temp function doesn't work properly and doesn't adjust the timing when hot. Check out the link for some major techy stuff from a Munich M division insider.... http://www.m5board.com/vbulletin/showthread.php?t=80820 - http://www.m5board.com/vbulletin/showthread.php?t=80820 I just need to find its location - I'm sure I'm being majorly thick but hey whats new. -------------

Actually wrong diagram. See link below to correct one for e28 m5 Description of sensors included in link. One is for ECU. One is for cold running to warm engine (switches map in ecu) One is for temp gauge in car including high temp light switch (orange light in dash) Ian http://www.realoem.com/bmw/showparts.do?model=5532&mospid=47202&btnr=11_0780&hg=11&fg=35 - http://www.realoem.com/bmw/showparts.do?model=5532&mospi d=47202&btnr=11_0780&hg=11&fg=35

Cheers everyone.
Now - the next silly question is this. Does anyone have a wiring diagram for the E28 M5 (, or M635CSi possibly) so that I can track the wire back to see where it doesn't go any longer?
