Retrofit of little OBC instead of analogue clock, temp. failure?

[Inphinity]

Hi.

I got a 91' 518 which had the little obc installed, now I have bought a
93' with a analogue clock. Then I thought it were changeable without any
other mods, but now when I turn the key to ignition the obc shows the message with the temperature with -30,0 degrees (Im from Denmark Europe)

How can it be?

I've heard that the models with analogue clock doesn't have a temperature
measurer?? installed. How to?

You are correct, you need to fit the external temprature sensor.

Do u know how to fit it?

[marti5]

Do you still have the 1991

[Inphinity]

Yeah, I have the old one..

By the way, it haven't got the gong installed i think.. Because when the temperature warning come, the diiiiing doesn't sound.

Well if youve got the old one remove the temp sensor and wiring and fit it on the new one, the temp sensor will be located under the front bumper.

The wiring is with the wiring set for the foglights right?
I can follow them to the wiring set for the headlights.. Can i just remove the tape around the wiring to get them apart or are they all together in a way?

[marti5]

The tape is to just keep all the wires together ,so yes thats all you need to do.

Cool, thanks bro.. I'll give it a shot..

Makes my life better when it shows the correct temp. not minus 30 degrees..

Happy new year
