My range dosent show up right. ill have like almost an empty tank and it will show up 147 miles left. i swaped out clusters... could that be why?

there is a hidden cap on the left bottom corner of the OBC. use a screw to pop it off and inside there should be a philips type adjusting screw. i forgot which direction you spin it, but you can adjust the fuel reading on the OBC with this.

how bout the 4 way switch on back of OBC, can't figure it.

In addition to 1000+1, you can also do 100+1 to see the coding plug firmware version you are running.

Don't bother trying to 'upgrade' to a higher number though, the typ codes go by which engine you have so all the range and mpg calculations are correct.

Thanks for the explain. I don't know the history of the car....just that it's a convertible that was dead for a while and is being transplanted with a new motor and interior work too - looks like a few wires were messed with, so I bet they had the battery disconnected for a length of time.

Uhr means hour in German.

If you want to say "2 o'clock" in German, you'll say "zwei uhr"


I havn't noticed the --UHR reading, but I imagine it's time...

[Fidhle007]

It's another version of the time display, I'm assuming a German one... When the battery is disconnected it automaticly defaults to UHR and Kilometers Per Gallon. When you get your time and date set if you go to the MPG screen and hit reset it will cycle you through the three display options: Metric (KPH and UHR) Another Metric (Imp: Imperial Miles per Gallon) and Dumb American Mode (What we all know and love...) I'll have to check my manual at some point again, because I know it described where the three different modes were intended for.

Anybody ever run into the 13 button displaying a " ---UHR " ?

-Ran into some guys with this showing, can't figure out what that could possibly mean.

mine shows that when my battery is disconected. when i go to set the clock it is in 24 hour mode.

^wrd up. i have a 13 button obc in my 90 325is, and i never use it. love the analog in the touring

I'll trade you my analog for your touring !! I'm in search of one, my Girlfriend has family in Canada one of which runs a car lot and does the auctions so i'm hoping to slide into one I am currently obsessed with this one

I knew about the fuel read but I didn't know about the code deal, thats hot...oh well analog clock FTW

I quess anyyone could figure this out, but driving constant speed and reseting average speed lets you know the "OBC speed".

That's a great trick too because as far as my research has found the OBC speed is bang on. I usually set my cruise right around 80 mph on the highway and then adjust it up or down 'til the OBC says I'm doing around 74.5. It's a little risky but if there's lots of traffic I'm usually fine and there is much less risk of my foot getting carried away and going over...
