Component
ENGINE AND ENGINE COOLING:ENGINE:ENGINE CONTROL MODULE (ECU/ECM)
What Happened
The engine control module in your Audi is like the brain of the engine, controlling how it runs. In some 2019-2021 A8 and 2020-2021 S8 models, a small pin is missing that's meant to keep water out of the module.
Risk if Unfixed
If this pin is missing, water could get inside the module and cause it to fail. This could make your engine stall, which might make it hard to control your vehicle and increase the risk of a crash.
Free Fix
Your Audi dealer will check the engine control module connector for the missing pin and install it if necessary. They'll also check for corrosion and replace the connector if it's damaged. This repair is completely free, and you'll be notified when it's time to schedule the work.
