7 – Notes

I purchased an aftermarket Audi Side Assist kit from Aliexpress and i had this issue with the Side Assist LEDs on the mirrors.

Everything was working fine, except for the SWA \ warning LEDs in the side mirror caps.

As soon as i check the Byte 11 bit 4 = 1 [SWA] in the 52 or 42 front doors ecu modules, the “Side Assist malfunction” warning appears on the virtual cockpit, and there’s a fault code on the 52 and 42 modules:
