Audi SQ7 Gear Display and Transmission Malfunction

Having experienced similar issues with my 2020 Audi SQ5, I can relate to these electronic display problems. The instrument panel malfunction started with an intermittent gear indicator blackout, followed by complete failure of the electronic display system. The root cause was a defective transmission control unit that affected both the gear indicator and transmission behavior. The automotive electronics system showed multiple fault codes related to the control module communication. The rough shifting and grinding sounds matched my experience exactly. This is indeed a serious issue requiring specialized attention. The repair involved: Complete diagnostic scan of the transmission control module, Replacement of the main control unit, Reprogramming of the new module, Full system calibration The job took three days at an authorized service center. This was not a simple fix, as the car dashboard and instrument panel are fully integrated with the transmission management system. The grinding sounds stopped immediately after repair, and the electronic display returned to normal function. A regular mechanic might struggle with this since it requires specific diagnostic equipment and software access. Recommend having this checked by specialists who work with modern automotive electronics, as continuing to drive risks further transmission damage.

Thanks for providing insight on the transmission control unit problem. Glad to hear your issue got resolved. Mine is nearly identical, the gear indicator went dark first, then the whole digital display started failing, causing those concerning transmission symptoms. Quick question, do you recall the total repair cost for the control unit replacement and reprogramming? Also curious if your instrument panel has worked flawlessly since the fix or if you noticed any other electronic display glitches popping up? Getting it scheduled at the dealer now, but trying to prepare myself for the bill. The car dashboard going dark is pretty unsettling, especially when you cant see critical info like the gear selection.

Got good news to share regarding the repair costs and results. The total bill came to 1000 Euro for replacing the affected control unit and reprogramming the system. Since having the work done by the specialist, the gear shift indicator and all instrument panel functions are working perfectly with no electronic display issues whatsoever. The automotive electronics are now functioning exactly as they should, clear gear selector readouts, smooth shifting, and no more concerning sounds from the transmission. The sensor problem that caused the dashboard display failure was completely resolved with the control unit replacement. Its been several months now with zero glitches in the electronic display system. The repair may seem costly, but considering how crucial these systems are for proper transmission operation, its worth getting it fixed properly to prevent more expensive damage down the line. Can confirm having a certified specialist handle this type of automotive electronics repair is the way to go. The comprehensive fix they did addressed all the instrument panel problems in one go.

I took your advice and visited a certified Audi specialist. After dealing with that frustrating gear indicator problem and transmission issues, I finally got it sorted. The repair experience matched what you described, they found a faulty control unit affecting the car dashboard and transmission. The specialist ran a full diagnostic scan, replaced the control module, and reprogrammed the system. Total cost hit 1200 Euro, bit more than yours but worth every cent. The gear selector now responds perfectly, and the instrument panel displays everything clearly again. Such a relief not having those grinding sounds anymore. Best part is the transmission shifts smoothly now, and all the electronic displays work like new. Really glad I didnt keep driving it with those symptoms, could have caused way more expensive damage. Thanks again for pointing me in the right direction with this. Definitely the right call going to someone who actually knows these complex automotive electronics.
