have a 02 x54.4. how do ya change the temp read outs to Fahrenheit. I don't know what 9.3C is and I'm to old to learn

Well, 40 degrees Celcius is a hot summer day in the Arizona desert (over 100 F). And 0 degrees Celcius is when water freezes. Let's just say I wish it were 9.3 degrees Celcius around here! It's been 15F (about -10C) all day!

I don't know how to do the switch on an X5 exactly... someone help me out here... isn't it where you push the right stalk on the cluster and then turn the ignition on and then off?

If that doesn't work, figure Farenheit is roughly close to Celcius times two plus 30.

9.3 degrees Celcius times two = 18 + 30 = 48 (it's actually 48.75 exactly)

20 degrees Celcius times two = 40 + 30 = 70 (it's actually 68 exactly)

But "times 2, plus 30" will get you close.
