3Q0 ABS Pump retrofit

[DV52]

Hi folks,

Anyone able to help me, I have a 2014/2015 MK7 GTI Euro Market from factory with ACC, Park Assist, Lane Assist and so on.
I retrofited PLA 3.0 (with manouver emegrncy brake) and Blind Spot + Rear Traffic Alert, but I had no luck to make the abs pump auto brake the car in reverse when in cross rear traffic like when leaving a parking lot, and not even the manouvering one, I just got a message in the TFT display like "press the bake" but no auto brake.

I have the follow ABS setup: SW:5Q0-907-379-M HW:5Q0-907-379-H, do I need to replace it to make it work?

Tks.

As part of the retrofit process - did you tell the ABS module that you installed PLA3.0? What is the value of Byte 5 and Byte 6 on Byte 24 on the ABS long-code string?

Don

Have you checked your coding with the spreadsheet done up by @Somnus (I think I got this from here or the Ross-Tech support forum; might wanna check to see if there's an update.)

Remember that Binary numbers are read from right-to-left. So the right-most digit in a Binary Number is Bit 0 and the left-most digit is Bit 7.
As you can see from my tables above, the changes to both modules are correct for the Byte/Bit descriptions in words!

I don't have any information about the ABS module on this car - so I'm not sure if the dataset, or the module itself supports PLA 3.0.

If the module has accepted the changes without any error messages - maybe try returning Byte 27, Bit 1 (PLA2 w/ Braking Intervention Installed) back to 1 (i.e. Byte 27=6A) - I'm guessing!

Any progress? I have basically the same issue.

This Abs is able to brake as if you exceed speed on pla parking maneuver it autobrake

I also think that there is non-zero chance that it is possible to crossflash 5Q0907379 into 3Q0907379 as they look kind of similar and both are developed by ATE

5Q0

3Q0

also when i compare unpacked frf firmware for those units it looks like they are pretty similar

(i unpacked FL_3Q0907379AB_0723.frf and FL_5Q0907379CK_0472.frf with frfdumper https://github.com/trick77/frfdumper)

Nearly all the strings inside the firmware for both 5Q0 and 3Q0 are basically the same... So looking forward for someone crazy enough to try to crossflash (disable EXPECTED-IDENTS in ODIS)

 

[oneb1t]

no i have the same issue as you
when brake occurs it will just show you message to press pedal

but this ABS unit is able to brake from different sources like ACC or automatic parking

 

[iichel]

I had several attempts flashing 5Q0 to 3Q0 but without any success. I tried to flash 3Q0 AK software into a 5Q0 BR HW, which is the factory hardware for i.e. the 2022+ Arteon R.
Unfortunately to no avail. The HW part is most likely the hydraulics part, while the SW is running on the 3Q0 brain regardless. I ended up purchasing a 3Q0 AK unit completely.
ODIS with idents off

I'm not trying to discourage anyone, but simply checking the HW for a crossflash is probably not a guarantee.

 

[oneb1t]

can you specify more info about errors you encountered while flashing?

 

[iichel]

goes to 6%, goes to 91%, error

 

[oneb1t]

so your part looks like this? and it was impossible to flash to it?

 

[iichel]

No, it looks like this:

You can see it has the exact same hardware (5Q0 BR) but the software is different. The software is 5Q0 EH.
Probably has a different brain that won't allow flashing to 3Q0 AK.

So I now have a 3Q0 AK unit exactly like in your photo.

[oneb1t]

i think that hardware is H82
so it should be possible to crossflash it

but it require modification of .odx file maybe this can be inspiration

[oneb1t]

yes automatic parking is working well for me but i have manual

our ABS unit have old firmware which does not support brake command from PLA unit as maneuvering brake arrived after facelift probably

this can be also interesting regarding crossflashing of units
https://www-drive2-ru.translate.goo...l=auto&_x_tr_tl=cs&_x_tr_hl=cs&_x_tr_pto=wapp
https://www-drive2-ru.translate.goo...l=auto&_x_tr_tl=en&_x_tr_hl=cs&_x_tr_pto=wapp

based on those "tutorials" i modified .odx file so ODIS is not going to reject it (file FL_3Q0907379AB_0723-modifiedFor033.odx)

 

[oneb1t]

they say that 3Q0907379AB is good choice (https://forums.ross-tech.com/index.php?threads/32610/page-2)​

it is cheap but crossflash will be more interesting path​

​

[oneb1t]

crossflash is not possible i bricked the unit today while doing it (i flashed it back to CK but now it does not want to run basic settings for EPB..)

so 3Q0 is the way
