B8.5 Audi A5 Sportback safety features

Post by imaninovakrz »

Howdy, folks! I was hoping to find someone with a facelift B8.5 who, ideally, has a Sportback and has retrofitted side assist installed. Anybody out there? Could you kindly send me your vehicle identification number (VIN) via private message? I need it to retrieve a stock dataset in order to configure the rear radar modules. Currently, they are set with the incorrect parameters, and the Audi backend server rejects the dataset files I try to download for them because my VIN does not have the factory-installed side assist.

maybe someone has 8t0907556b zdc, odx, or xml files.

Parameterization on the modules is basically what I need. I have the flash data, but flashing them will leave them blank. Then I have to find the right dataset, which is a challenge because my car didn't come with side assist installed when it was manufactured.

If anyone can provide assistance, I would greatly appreciate it.

Module 3c's VCDS report, what is it? Ideally, you'd have two separate modules. On the right side, you'll see a master 566, and on the left, you'll see a secondary 568.
Here are the codes I used for a retrofit that actually worked.

hello, I encountered two calibration errors, which is to be expected given that I retrofitted the side assist. Additionally, I encountered a dataset error in vcds, which indicates that I need to load the correct dataset onto one of the modules. Unfortunately, the module in question was loaded with a dataset from another car, which is why the error occurred. The mistake is

[implausible dataset] 267776 - B2012 00 [00001001] - -

I'm getting this error because the module wasn't pulled from an Audi A5. The slave module was fine, and it had the correct dataset. The master module, on the other hand, isn't an A5, and I want to upgrade it by flashing it. However, it will remain empty. To fix this, I need a VIN number from a factory-fitted Audi A5 sportsback, since my car didn't come with side assist. Another option would be to buy a new module, but I'd rather not.

So, I flashed the modules, so I guess I don't need vin anymore. Haha! The only remaining codes were for basic settings calibration, which I successfully coded without the use of any coding equipment by fooling the sensors into thinking they are sitting perfectly aligned. I was able to clear all codes after obtaining a donor vin.

Now that I've done the testing, I know that the switch that activates the side assist is wired wrong. Everything in the 3C lane change works and lights up except for the switch, but I did advance measurements inside the VCDs and checked the status of all the side assist parts. When I press the switch the light turns on but soon as I let go it goes off so I think I wired it in wrong so after this it should all check out.
