Audi Q2 Transport Mode Causing Total Electric Failure

As someone with some experience working on Audis, I had a similar situation with my 2015 Audi Q3 TSI last year. The transport mode activation is actually quite common on newer Audi models and can cause these electrical system disruptions. When my vehicle settings showed transport mode, the key fob functionality was limited and several systems were inactive. This is a safety feature that dealers use during vehicle delivery, but it can sometimes activate unexpectedly. Since your vehicle is new, this should be covered under warranty. The solution was straightforward in my case, the dealer needed to deactivate transport mode using their diagnostic equipment. They also performed a complete system reset which restored all functions, including the immobilizer and key fob programming. The entire process took about an hour and required specialized diagnostic software. After the reset, all electrical systems returned to normal operation, including navigation and vehicle settings. To help provide more specific guidance, could you share: Current mileage on your Q2, When these symptoms first appeared, If any warning messages showed up before this happened, Whether any recent maintenance or battery disconnection occurred This information would help determine if your situation matches what I experienced or if there might be other factors to consider.

Thanks for the helpful reply. After running a diagnostic check at home with my OBD scanner, the transport mode seems to be stuck due to an interrupted software update. The car currently has 125189 KM and last service was done just 2 months ago. The car electronics started acting up right after I had the battery disconnected to clean some corrosion off the terminals. The automotive diagnostic tool confirms no major electrical faults, but the car configuration settings remain locked in transport mode. Based on your experience, I will schedule an appointment for a proper software update and system reset. Good to know it is likely just a programming issue rather than a deeper electrical problem.

Thanks for providing those additional details. That battery disconnection scenario matches exactly what triggered my transport mode issue. When the power gets interrupted during any kind of system update or configuration change, these Audi models can get stuck in a safety state. The good news is your diagnostic check results align with what I experienced, no actual electrical faults, just a software state issue. The dealer will need to perform a complete software update and reset the car configuration settings using their VAS diagnostic system. In my case, the total cost was around 150 Euro for the diagnostic check and software reprogramming. Since your mileage is similar to what mine was, you should expect a comparable repair process. The key fob will likely need reprogramming as part of the procedure to restore full functionality. One tip from my experience: make sure they check all control modules during the update. Some workshops only reset the main unit, but secondary systems like navigation can remain locked unless properly reinitialized. Would be helpful to know if the repair resolves your issue once completed. This seems to be a somewhat common occurrence after battery work on these models.

Based on your thorough explanation and experience, I really feel more confident about the repair path forward. The battery work definitely seems to have triggered this transport mode issue, and your similar experience helps confirm my suspicion that its primarily a software problem. I will make sure to request a complete system check of all control modules during the repair, not just the main unit reset. The 150 Euro cost estimate for the diagnostic check and reprogramming seems reasonable considering the work involved. Will schedule the appointment for next week to get the software update and vehicle settings reset completed. At least knowing the key fob reprogramming is part of the standard procedure helps explain why those functions are currently limited. Thanks for confirming this is a known issue that can occur during battery maintenance rather than a major electrical problem requiring extensive repairs. Once I get the car sorted out, I will provide an update on whether the immobilizer and all systems return to normal operation after the software update. This information could help others who encounter similar issues after battery work on their vehicles.
