Hi Clifford, thanks for the reply! I really want to know what's causing it, but as I've tried so many things and nothing worked I think I'll be happy if it just disappears 🙂 Have you got any suggestions what I can try, I'm happy to provide more info if needed? * btw I'm using OBDeleven on iOS, which is slightly restricted compared to the Android devices (as far as I know) and resetting of the gateway module doesn't really work...

Hello everyone, This is my very first post in a forum, and I have to admit — I’m a bit desperate… I bought my A3 over 2 years ago. At the time, I had a Carista and there was a fault code U112400, but I ignored it for a while. A few months ago, I got an OBDEleven and started digging deeper. I’ve read countless threads across forums and tried almost everything, but I can’t get rid of the fault. I've tried with ChatGPT and Gemini - but they don’t seem very familiar with the VAG vehicles 😉 So as I said I'm getting a bit desperate and was wandering if someone has similar vehicle may be you can share the long coding for the gateway module, so I can compare it? ’m not asking for blind copy-paste — I just want to compare byte-by-byte to see what might be causing the “Additional installations detected” fault. * My Audi has the technology pack (with virtual cockpit) and I disconnected and uncoded the phone box (it was useless), rear parking sensors (only), auto lights and rain sensors as standard, as far as I know nothing has been retrofitted. Here is the fault I'm getting: VIN: WAUZZZ8V0KA043894 Car: Audi Year: 2019 Body type: UNKNOWN Engine: DADA kW ( hp) l Mileage: 95205 km --------------------------------------------------------------- 19 Gateway System description: GW MQB High Software number: 3Q0907530AA Software version: 4366 Hardware number: 3Q0907530C Hardware version: 442 Serial number: 0008729094 Faults: U112400 - Data bus Additional installations detected static And in case someone can actually read the long coding and translate it in English, here it is for mine: 03 01 00 04 3F 08 56 00 5B 00 02 4A 08 0B 00 00 00 01 01 00 00 00 00 00 00 00 00 00 00 00 PS. I should mention that I’ve made a lot of changes in the Gateway module over time — roughly 95% have been reverted to factory values, but this is the code as it currently stands. Any help will be much appreciated, TIA!
