There are 2 or 3 depending on year, one towards the front of the head, one near the middle and one towards the back which is not fitted on early cars and is just for over temperature so it can be ignored.1998 p38 2.5 d bmw 6 cyl automotive
Hiw many temperature switches dos that have please?
I did exchange a green one under the manifold.
Is there another one somewhere ? And if so, would anyone have the location and partnumber to hand.
Thank you
The front one is brown ,the back one is black and is used to activate the a/c fans on later models if gets hot as posted.Ive found the printout but it hasn't got the part numbers sorry.Try lr.com I'd look for you but got a doctor appointment.There are 2 or 3 depending on year, one towards the front of the head, one near the middle and one towards the back which is not fitted on early cars and is just for over temperature so it can be ignored.
Well done Jack, I was in a rush and got it wrong,the brown sensor I mentioned was fitted to the Omega cylinder head.98 MY with EGR (probably AC) id guess your front sensor is a 2pin blue unit.
Think the 3rd black sensor (stc2254) came in ‘99 but it’s possible your engine could have it. If not it’s a blank
You can just take a look with a torch to check is best. Remember you are identifying the colour of the sensor not the connector on it
Zoom in you can see
View attachment 252456 Sensor 1 - blue gauge sender (2 wires) /green connector
Sensor 2 - green ecu sensor/black connector
Sensor 3 - a blanking plate (if there’s one in there it’s the black one)
^^^ is early model yours may vary so take a peek on yours. If you have a brown sensor it’s stc 2253
My listing was showing the green one for the ECU but the guy that gave it to me wasn't sure, switch the ignition on and pull the connector and see if the gauge stops working. If it does then the other is for the ECU.Cool
Thank you.
We replaced the middle one ( green ) but it was for the gauge I believe.
Don't have the rear one, even i do have Aircon.
It's a 1997 as far as I can tell from data on nanocom. Original engine.
I need the sensor going to the becm / ecu.
Just can't seem to get info from bearmarch or 4x4 Island on it as they only point to the green one for the gauge.
+1 to that. Gauge is the front sensor. the rear one can be ignored fitted or not.The middle sensor (green) is the ecu temp sensor.
Invalid fault sometimes means nothing, does the car run OK?Oh. OK. We did exchange the middle one. Which was green on mine.
Still got this temp fault.
Isn't that fuel heater just part of the winter protection kit along the heated washers?The box the fuel filter screws into is a heater unit that can fail but not very often. Check the connector/wiring to it, but be careful the heat and age can make things brittle.
(Just re read your post looks like it’s working according to Nanocom)
