Seats not get warm enough? Maybe they get uncomfortably hot? You can change that with the BMW Scanner and PA soft.

Double click on the SZM from the menu:

Find line 0x30 on the screen that comes up (NOTE: You may need to click "Read EEPROM" to bring up the values):

http://img.tapatalk.com/d/14/04/04/amu9adaz.jpg

The six highlighted values are the temperature in Celsius, 3 for the driver seat, 3 for the passenger seat. driver seat low, medium, and high. Passenger seat low medium and high. Get it?

The values do not appear like Celsius numbers because they are hexadecimals. In the picture the values are 26, 29, 2D. In decimal (Celsius) that is 36, 41, and 46 degrees.

You can use this page to covert the values back and forth yourself to get an idea. I found a free app for my iPhone that did the same thing. http://www.statman.info/conversions/hexadecimal.html

I upped the values to 42, 46, and 50 degrees, converted them to hexadecimal, then entered the values into the highlighted values. Once I did that I clicked "Write EEPROM" and it wrote the values into the car. After that, you're done. Test out the seats.

Epic! Had no idea stuff like this could be modified.

Nice! I like your idea writing the program in front of the title. That will definitely help searching, down the line.

Def thanks for sharing, I'd like to dial down all the settings, "3" is completely useless as it's way too hot for me.

That's cool. I need to increase my values. Of our two cars one is super warm and the other just warm (M3).

I don't see the screen shown when I "Find line 0x30 on the screen that comes up:"

Do you have to "Read EEPROM?"

Yup, was just about to do that now that I sat down with my lunch. :-) Let us know how it turns out.

Wait...is this the same software to code out the double-pull, program the trifecta, etc or is that different?

Double-pull I believe is apart of this program. The actual program to code all those and more (trifecta) would require ncsexpert.

It's me telling my passengers "you have to pull it twice, it's a BMW thing" when they ask what's wrong with the door handle.

It's like double-clicking with your mouse! We can take care of that with PA Soft, but you will probably want someone with NCSEx to do some of the other stuff like hazard breaking (or whatever the BMW lingo is for that).

I changed my seat temps last night using PA Soft....I'm glad I did this. Bumping up the seat temps was just what my back needed! :)

Did you go up on all three? I went down to prevent toasted buns.

I went up on all three because I have back issues...used them tonight and I like the new settings much better...or at least my back does :)

The settings on my ///M haven't been changed yet...I think I will be doing this sometime over the weekend :)

It surprises me to hear about the variation in the seat temps. On other forums and here it seems like some get too hot and others not hot enough. Mine are underneath the padding instead of in it so it makes sense mine wouldn't get warm enough without doing this mod.

Anyway, glad to hear this will help your back, cakM3!

I know this is reviving an old thread (but still useful). I went to the website listed above and the decimals I get for values 26,29,2D=38,41,45. Is OP wrong or am I confused?

Windows Calculator also has HEX -> DEC conversion feature and I used that along with the website mentioned above. Your numbers look right to me.
