MDM euro Coding

[hdubf80]

I got euro mdm coded but my tpms is acting up. Control message won't go away and I'm getting messages in my dash saying to reset. I reset sometimes it works sometimes it doesn't. But the main problem is the control message won't go away. Please help...

Yes, I did code other cars as a favour to fellow local enthusiasts. But I am no pro in terms of coding and only have the skill to do it on site. Unfortunately, I can't help you with this one .

I was just as clueless as you a few months ago. I bought a cable and a laptop and can now doodle around. You should try it out, it is not that difficult and kinda fun .

Do u own a US spec build? I think one of the earlier instructions for US was to code the TPMS as euro; however more up to date instructions seem to be to leave this as US. May or may not be related, but worth a try?

my tire pressure was just low lol. Filled it back up to 32psi and it went away. Thank you for the reply.

The US setting is 100kpa, the only other option in my car says "unknown" and i'm afraid to select it and actually code it to the car, fearing some sort of mega failure.

anyone else have this issue? if so, how did you fix it?

I'm having this same issue. Has anyone found a fix for this? Thanks!

That is because the ECE VO value for CalLrPDevMax (and hence the Euro1 coding, using the terminology of post #146) has changed from Werte=24 to Werte=20. There are changes to several other parameters (some of which are mentioned in this post) too and they are likely to be interrelated to some extent.

You can still code the previous Euro settings by editing the Werte value directly to 24, as the literal value (e.g., "50kpa") is irrelevant, or you can start testing the updated Euro MDM settings

OK I decided to update my Euro2 MDM cheat sheet using Werte's to be future proof, but now I am thinking if I change CalLrPDevMax to 20, is this value backward compatible?

In the 58.3 version of DSC cafd, the only values are (UNK_PARAM_0 = 20, 100kpa = 28), I would have thought if 24 was still a valid value, then it would list all three values (UNK_PARAM_0 = 20, UNK_PARAM_1 = 24, 100kpa = 28), opinions ???

PS: do you have a github account so you can comment/review on my changes ? thanks. https://github.com/thisisdave/bmw-f/tree/master/cheats

As I mentioned above, there are changes to several other parameters too and they are likely to be interrelated to some extent. IMO, the only way to know how well this new value works with the previous settings is to test it.

Why? The literal values are just shortcuts to the Werte values used by BMW for VO coding.

I would try the new value of 20, but I doubt I'll notice anything. We need someone like CanAutM3 we can only assume that lowering this value from 24 to 20 can only mean something more fun as the default value used in US cars was 28!
Ok just met stealth70mde , and coded Euro2 MDM with the new setting of CalLrPDevMax=20 so waiting for driving impressions

Am I now a guinea pig of some kind?

I can reassure you that I didn't crash driving back home.

OK then, something to do this long weekend . Is that the only parameter that changed?

I will try it out and report back .

However, testing out DSC/MDM stuff is something I prefer doing in the winter where you can get much greater slip angles without having to go too fast.

yes thats the only one that changed, BTW, i think it changed in more recent software versions, not sure what your I-step value is and if that value is backwards compatible ...

And I have no trouble getting sideways with EuroMDM :-)

That is not a correct statement: CalLrPDevMax is the only parameter that has changed among those that were previously identified.

There are now additional differences between "US" and "Euro" MDM.

ok that is the only one changed that was part of the original set of parameters as mentioned in post 4?

I just re-coded the cheat sheet and had a 58.3 DSC cafd open, and manually checked every single parameter mentioned in post 4. If I missed something, please correct !

Latest DSC CAFD from PSdZData 58.3 (00001a33_001_003_002). Left is Euro1 and right is US:

• C_Laenderkennung Left: ECE = 00 Right: US = 01
• CTpmsMarket Left: EU = 00 Right: US = 01
• CPrewarnEnable Left: enable = 01 Right: disable = 00
• CPrewarnIgnition Left: enable = 01 Right: disable = 00
• CalLrPDevMax Left: UNK_PARAM_0 = 20 Right: 100kpa = 28
• CPInitRangeMax Left: 80kpa = 20 Right: 200kpa = 50
• UiaSetLevelPc Left: 20% = 14 Right: 25% = 19
• UiwSetLevelPc Left: 15% = 0F Right: 20% = 14
• UiwSetLevelDistMin Left: UNK_PARAM_0 = 08 Right: initwert = 0C
• CalTimeConfUiw Left: UNK_PARAM_0 = 02 Right: initwert = 0A
• CDtAmbPrewarn Left: UNK_PARAM_0 = C8 Right: initwert = 0A

ok cool, so there are new parameters you show above that were never mentionned in the original EuroMDM coding, so when I answered CanAutM3 , it was within the scope of what we coded before ... can we agree to disagree now ?

That is exactly what I said 3 posts earlier:

CalLrPDevMax is the only parameter that has changed among those that were previously identified.

There are now additional differences between "US" and "Euro" MDM.

OK, so I just coded this latest in my car. I just left CTpmsMarket to US (01) as was previously discussed. I will go for a spin a little later when time permits.

Have you tried this latest setting?
How does it feel?
How did you set the CTpmsMarket?

I have not tried, as I have a new set of summer tires that are not broken in yet.

The other thing to keep in the back of your mind as you test this is that the above is a comparison between the US and Euro settings in the latest CAFD, but (going by memory) there are additional differences between the US MDM setting from earlier CAFDs and those in the current CAFD. So it is a bit tricky if you have not updated your firmware.

You lost me. Can you re-explain?

Remember, I am a true layman in terms of coding
