I own a 2001 Mercedes C. L. K. with climate control. I'm not sure if anyone has posted this yet but I thought is might be of interest to some people out their. If you hold down the restore button on the climate control for approximately five seconds a series of numbers will show up. The numbers on the left correspondence with different features of the car that are represented with the numbers on the right. The numbers on the left I believe are between 1 and approximately 43. I'm not sure what every number means but some of them are for RPM's #21, engine temp # 6, another is for battery voltage #24, for those of you who are into car audio, the higher the voltage the more you can get out of your stereo system, and actual ground speed, just in case your odometer is off. I noticed that mine was off slightly. I'm not sure which number it is but you can figure it out while your driving, maybe bring someone with you. All you need to do is push the auto button on the top or the bottom to scroll through the numbers. Try it out and you'll see what I'm saying I will post pixs.

The voltage is based on the output of the alternator to the battery it will go higher when your driving and other accesories are off. If your concern is for the stereo equiptment then use a stiffining cap. 1 farad should work. I'm not sure if any of the numbers can be adjusted. I think its just a display.

that is pretty cool... i guess MB makes everything easy access so they don't have to use their diagnostic computers that much....
i wonder if the dealer would actually tell you what each display meant?

Out Of Control!!
Thanks,
I'm either off by A LOT, it isn't in mph, or they designate something else. Does it update in real time, or do I need to maintain a constant speed for several seconds to get a correct reading?
Thanks,

Awiner did a post on this in the CL forum...Look for A/C dialog mode in search... it gives you a list of all the numbers and what menu they pull up I thought you guys knew bout this from before...Can someone tell me if it works in the 2003 E-Class (W211)?

The climate control also has a diagnostic mode where the car error codes can be viewed and cleared.
Here's a list of the meanings of the various settings. Not all cars will have all values. Values of temperature are always in Centigrade; values of speed are always in KPH.
Code:
01 = In-car temp sensor 02 = outside temp sensor 03 = left heat exchanger (heater core) temp sensor 04 = right heat exchanger sensor 05 = evaporator sensor 06 = coolant temp 07 = refrig. pressure in bar 08 = refrig temp sensor (23*9 = 23.9deg C) 09 = nothing 10 = Blower control voltage (great for evaluating blower controller problems) 11 = emissions sensor (B31) e.g. 3.1 = 31.v 12 = sun sensor 4.2 = 4.2v 20 = aux fan control 6.1 = 6.1ma (max 10ma) 21 = engine speed 22 = vehicle speed 23 = Circuit 58d e.g. 99 = 99% of battery voltage 24 = BATTERY VOLTAGE e.g. 12.5 = 12.5v 30 = left rear air conditioning heat exchanger temp sensor (not all vehicles; obviously) 31 = right side 32 = rear evap temp sensor 33 = blower control voltage rear 0.8(MIN) - 6.0(MAX) 34 = left rear temp selector 35 = right side 38 = software status e.g. 37 rear air conditioning 38 = hardware status e.g. 37 , rear air conditioning 40 = control module version software status (?) 41 = control module version menu hardware status 42 = control module variant code 1st number 43 = variant code second number.
