As many of you know, my car is constantly in service.

Unfortunately, I lost some coding during my last visit, as the dealer apparently updated software for some modules.

Strangely, since then, my heated seats on the third level get extremely hot, in particular, the seat back... so much so that simply touching it with your hand feels like it burns, causing you to quickly pull your hand away.

When connecting with Rich (who's amazing, as those who know, know) to get coding back, he saw that the seat bottoms and backs are set to different temperatures on the third setting and that the seat back is programed for 119 degrees Fahrenheit.

Some questions:

1. Has anyone noticed a change in their heated seats temperatures over the years, after a service visit in particular?

2. Does anyone know what temperature your heated seats – the seat backs in particular – are running at?

I like hot heated seats and always thought our cars had great heated seats, but mine have become unbearable.

Problem being... Rich can code to car for whatever [lower] temperature I desire, but I’m not certain what the ‘right’ number is; whatever I may or may not have had before. So I'd like to know what everyone else may be running at.

Also…

3. As the heating elements age, is there any way that they may go bad and heat up even MORE than they should?

Thanks and happy and safe motoring out there if anyone’s in the Northeast storm area!

119° F is equivalent to 48° C ... so if you look at the coding parameters in the Bimmercode app (see pic below)...you are at the high end for LEVEL 3. If you had the Bimmercode app...you could easily lower the temp setting for the seat back...or have someone change it for you to one of the lower settings available. Good luck.

Perhaps level 3 is too high for your personal situation. I only use that level when I'm wearing a heavy coat in very cold temperatures. If I'm wearing less clothing or thinner clothing...then I only use the lowest heat setting...knowing that at some point the comfort level will be too high and I'll have to readjust the level. Using a higher level doesn't warm the seat up any faster.

BTW, I wasn't sure what model to go with...your car info indicates you have an f01 7 series...but you've posted this question on the f10 5 series forum. I used the f01 7 series supported coding parameters from the Bimmercode app.

Should be able to adjust the heat levels in Idrive. Or buy bimmercode and then you can find your perfect setting yourself.

Many, many thanks, QSilver7; so helpful!

Also... wonderful insight such that using the higher level doesn't warm the seat any faster!

And thank you, CanadianTSi as well.

I truly appreciate it.

Be well.

QSilver7 or anyone else:

Can you please find out what the original / default heated seat values are that BMW uses, for the seatbacks and bottom?

And if those values may have changed over the years with newer module software versions?

This is driving me crazy getting the right / desired settings back!

Thank you.

I changed my settings with the Bimmercode app so I don’t remember what each one was exactly...but I seem to remember them all being close to the middle of each range.

But regardless of coding parameters for the range of selected front seat heating...you have the ability in iDrive to adjust the front seat’s heat temp, too. Go to SETTINGS in iDrive, then scroll down to CLIMATE...you should see a selection for seat heating adjustment for the driver’s side and passenger’s side. I have this ability in both my 2013 f06 650ix GC (has CIC) and 2014 f15 X5 (has NBT).

EDIT: went out to the garage to snap a few pics to show where to go in iDrive to adjust the front seat heating. I will post pics from both vehicles since one is CIC (pics1, 2, & 3) and the other is NBT (pics 4, 5, & 6)...the wording is slightly different but the procedure is the same...and I’m sure this would be similar for the NBT ID4/ID5/ID6 iterations as well.

Many thanks all your support of this wonderful community, QSilver7.

I think those settings only refer to heat distribution - not to raise from the settings the car is coded to.

Meaning, if someone wants to use heated seats, but doesn't want both the back and bottom to heat, they can reduce one or the other.

I'm pretty sure the pads aren't individually adjustable...

That's correct. Only changes how much heat is in the rear of the seat vs bottom of the seat. The button on the climate control unit is the only thing that controls the level in three steps, plus off.

I'll look at what the default stock settings are for each level in ESYS and report back so you can compare.

Thank you very much, SWFlf10.
