dinksy: that's far too general a question to be able to provide an answer- more information needed. What is the specific error message in yuor scan report and what actual changes were made to the factory equipment in the car? Don

So I've had 2 lots of vcds coding done to my car to activate auto hold without the physical button. And it keeps failing due to epb errors. I've also paid for someone to diagnose it over the internet via vcds. To no avail.
The coders have stated it should work with every A3 8V but mine is the exception.
It comes with ACC, lane assist, side assist, pre sense and they say as it's loaded may be causing a error. Which they can't find.
It's infuriating as it's £450 fitted here in the UK. And it's a must for me. Just wish it was fitted as standard from the factory.
Any help would be great. 👍🏻

@dinsksy: hmm........ still far too general an explanation. "without the physical button"? I assume this was the factory build condition - does the car have the button now? What are the details for the "2 lots of VCDS coding changes"? What is the long-code string on the hex03 module? What is the exact details of the errors (ALL faults) on your scan report?

It does not have the button installed in my vehicle
The coding below I have got from the forums.
My coding in vehicle is

When the coding is activated auto hold comes up can't activate in DIS and then electronic parking brake error.
I've reverted it back to original coding string and no issues. I think it's because it's a facelift and hybrid.

Yes - those changes look OK Byte 08-Bit 1 Byte 19-Bit 6 (Byte 19 is the mirror to Byte 08) Byte 23-Bit 0 Maybe also Byte 28-Bit 4 Here's how your current HEX03 long-code looks

I will try your extra coding and see if that does it. Do you think it will still work without the need of the switch.
Appreciate your help Don.
