Soundaktor on A3 e-tron (hybrid car)

[chefranov]

Hi! I retrofitted Soundaktor on my Audi A3 2017 Sportback e-tron, I added A9 module in Gateway and coded Byte 19 Bit 5. I flashed with unlocked SW (tried with/without FPA). But I have one error in A9 and it doesn't work:

CAN, no message U1121 Keine Funktion durch CAN FehlerMotorsteuergerätebotschaft fehlt-> keine Klangerzeugung

Maybe for hybrid car need more coding or another FW? I have Drive Select. VW Golf GTE similar to my car and there is working fine from factory.

Which firmware did you flash exactly?

Also make sure your FPA dataset in your gateway has soundaktor support, otherwise it will not work.

[chefranov]

Which firmware did you flash exactly? I tried these:

• FL_3G0907159___0006_UNLOCKED_1.odx
• FL_8W0907159D__0006_UNLOCKED_NOFPA.odx
• FL_8S0907159___0004_UNLOCKED_1.odx

Also make sure your FPA dataset in your gateway has soundaktor support, otherwise it will not work.

How can I check it?

Maybe my engine missed in dataset?

[jilleb]

I will search for A3 etron/hybrid fpa datasets. It's not possible to see what dataset is currently in your car, unless you have access to online Vw/Audi ODIS.

The fpa dataset has a list of supported modules and settings for each module in each mode. If soundaktor is not there, there will be no message to the soundaktor.

Is possible to use without FPA?

[jilleb]

Only with the nofpa firmwares. You can try a few of them.

I tried but issue is the same

[chefranov]

Could you make dataset for GTE without FPA? My car is similar to GTE

[jilleb]

I'll make a few test firmwares for you tomorrow, with Audi firmwares as a base, that should work. There's a slight difference between Audi and VW firmwares, the other parts of the firmware can be different which can be the reason for this

Thank you! Will wait

@jilleb any news?

[chefranov]

@jilleb any updates?

[jilleb]

Had some surprise deadline at work, so you have to be a bit more patient 😅

[chefranov]

@jilleb still deadline at work? 😅

[jilleb]

No, but work builds up over time ;-)

Try this: https://www.dropbox.com/scl/fi/r9jaqzang5xwvycsvk44x/FL_3G0907159___0006.MODIFIED_DEFAULT_GTE.odx?rlkey=82va7vnrkey9m9n9wel88xjoo&dl=0 Regular GTE firmware, has default sound ON, so it should work even when gateway isn't sending any signal (because the soundaktor is not in the FPA dataset)

or this:

https://www.dropbox.com/scl/fi/8awxhat6ztdlac897h3zz/FL_3G0907159___0006.MODIFIED_WITH_AUDI_DRIVER.odx?rlkey=egrquvxb7g5q17bw01r06q60k&dl=0 The same firmware settings, but added to an Audi firmware.

Or this:

https://www.dropbox.com/scl/fi/kxmrwxehlh6sn4oll9spj/FL_3G0907159___0006.MODIFIED_DEFAULT_GTE.MODIFIED.odx?rlkey=h1mye6y2zphgszt201i9b2aow&dl=0 The same regular firmware as the first, but in "negative mode" for sound. This sometimes works between Audi/VW. Worth a try.

Thank you! Will check

[chefranov]

@jilleb hi! Today I tried your fw.

These can't be installed. ODIS can't flash it: FL_3G0907159_0006.MODIFIED_DEFAULT_GTE.MODIFIED.odx FL3G09071590006.MODIFIED_DEFAULT_GTE.odx

This was installed: FL_3G0907159___0006.MODIFIED_WITH_AUDI_DRIVER.odx

But now I have two errors instead of one as before:

P1385 - Keine Funktion durch internen Fehler des Controllers-> keine Klangerzeugung
U1121 - Keine Funktion durch CAN FehlerMotorsteuergerätebotschaft fehlt-> keine Klangerzeugung

[chefranov]

@jilleb hi! Any news? I found here datasets of gateway but for e-golf maybe it can help you

[chefranov]

Hi @jilleb! Did you have a chance to find solution for me?

[chefranov]

@jilleb heeeelp me please 🥺

[chefranov]

Fixed. I connected to incorrect CAN Extended (CAN5). Correct one is CAN Drivetrain (CAN1). CAN for Engine and A9 should be are the same:

Hi everyone, I wanted to ask if it is possible to load the RS5 firmware onto a Passat GTE without driving profiles, but only with GTE mode. It is possible to modify the file in order to have the RS5 sound only in GTE mode. I think A3 E-tron is similar Thank you
