Hi guys.

I own a 07/2021 G21 Car with Brake Auto Hold function but I didn't like it motion.
So I researched the function change coding and finally found it!
These parameters change function until now 1-step operation to 2-steps.

DSC-BRS(3D72)
3000 DCS_CODIERDATEN_ALLGEMEIN_KOMMUNAL
C_epb_dynomod_rbt_e(DCS_CODIERDATEN_ALLGEMEIN_KOMM UNAL_32_32_1) nicht_aktiv(00) to aktiv(01)

3005 DSC_CODIERDATEN_ALLGEMEIN_G2x
C_Variante_AutoH_Conzept_I(DSC_CODIERDATEN_ALLGEME IN_G2x_0_0_1) Conzept_SSM_avh_min_Driver_pres(00) to Conzept_SSM_avh_min_Driver_TQ(01)


If you would like try it.

Before Brake Auto Hold Function

After Brake Auto Hold Function

[xnick101]

I don't understand what is the difference after coding this in?

[Pyo_man]

BMW's original Auto-H function forces the vehicle to engage EPB every time.
I didn't like this.
But by this, you can simply activate the brake hold just by depressing the pedel like Mercedes. (Of course Auto-H must be on.)
This is what OP explained as "2-steps"

Thanks!

Thanks maximking for following my minkara!
I think that's coding is great for improving the Auto Hold fanctionaly.
But, it's a pity that it's effective only for G20/G21/G22/G26.

However, I'm really happy to be able to talk you all.

Thank you.

Good catch, I will try it as well.

i will send you a pm , buddy

Maybe model or market specific, because my G22 AutoHold function only keeps the brake pressure. EPB is loud enough that I can tell that it does not engage when AutoHold holds the car (at least not for awhile, may it does if I stay with long enough).

Huh? What is EPB?

Yeah it doesn't engage the EPB, just holds the brake pressure (or builds up pressure on its own as it has an Elecronic Brake Booster).

[Radhaz75]

I just tested my 2019 330i with iDrive 7/2021 and it only engages the parking brake when I shut down the engine, otherwise it appears to just hold the regular brakes until I tap the gas at which point it lets go immediately.

Although mine says "Park" instead of the parking brake icon shown in the videos, it appears as green when its holding the brakes and red when the electronic parking brake is engaged.

It's really hard to see a difference in those 2 videos in before and after for me.

I feel like it did always just engage the electronic parking brake back when I was on iDrive 3/2021 but I'm not certain and there's no way to tell now.

Ultimately, I decided I don't like the feature because when pulling into my garage and inching forward, it will engage the auto hold even though I'm still trying to inch forward and stepping on the gas at that point to disable it just seems dangerous.

[Pyo_man]

Hi Radhaz75.
Thank you for tried it.

I'm sorry this coding explanation is poor.
I think I'd gave to addinational explanation.

Operation before the coding
Auto Hold function was doing as soon as car stopped when Regardless of how much the brake is applied.

But operation after coding
it's not doing as soon sa car stopped.

First, The car stop with a bit depressed brake.
Next, If the brake is further depressed while the car was stopped, the Auto Hold is activated.

For example
When a car pause, the Auto Hold function is doing.
But after coding is not.

I'm happy to if you could understand.

I've watched both videos and I have to say it's so hard to see the differences. I shoud get a G20 and try the coding and feel it.lol

[drdino]

As it is, autohold is engaged as soon as you come to a stop and there is light pressure on the pedal. Judging by the description of the op, after the coding it will not be engaged with light pressure but will need more pressure, much like Mercedes where you need to press the pedal more and with a higher speed.

This is a good find. Similar to Audi car Auto start stop function. If brake is slightly applied (enough to stop anyway) then engine is still on, but brake depressed further then engine is off.

In other words, it senses the amount of brake force applied, soft enough : do nothing - Hard enough : take action.

It required a bit of practice to control your foot.

[Radhaz75]

Ahh thanks for the explanation. That makes a lot more sense and would definately fix my issue of pulling into my garage.

I looked for the above codes in Bimmercode but couldn't find them in any modules so I assume it's a Esys/Bimmerutility thing. Any word on if this is codable with Bimmercoder?

Hi Radhaz75.

Unfortunately, This coding can't using Bimmercode because there's not access the 3D72 Module.

I'd recommend using BimmerUtility what support this mappings.

Thanks.

[Wackjam]

Has anyone tried this recently?

I can't find the second part of the coding below using the Bimmerutility mobile android app.

3005 DSC_CODIERDATEN_ALLGEMEIN_G2x
C_Variante_AutoH_Conzept_I(DSC_CODIERDATEN_ALLGEME IN_G2x_0_0_1) Conzept_SSM_avh_min_Driver_pres(00) to Conzept_SSM_avh_min_Driver_TQ(01)

Has the name or module changed?

Thanks

Pyo_man - is there similar coding for the Auto Start Stop System?

On my G80, the Auto Start Stop activates when slowing down at about 1-2km/h (even before the car has come to a complete stop). Would be good to have Auto Start Stop only activate after a firm push on the brake pedal after the car is completely stationary.

It shouldn't be otherwise it would jerk the car violently while the car is still moving and engine shut ? May check with the dealer ?

If you need to have auto start stop memory set bring it to me, I have bimmercode and can code it for you.
