Volkswagen has recalled 8,383 2017-18 Audi A3 Cabriolets and A3 sedans for problems with their Engine Control Units (ECU). Also called the Engine Control Module (ECM) in other vehicles, the ECU is the master underhood computer. It takes its input from subsidiary systems such as the transmission, brakes, suspension and the like. It also holds the software that affects how a vehicle operates.
Software glitch could bring stall
In this case, there is a glitch in the ECUs of the Audi A3 models that could result in stalls in traffic. If a vehicle stalls suddenly in traffic it may be involved in a crash, injuring the occupants of the Audi. If another vehicle is involved, it could also result in injuries to occupants of the second vehicle.
According to Audi, the ECU could misinterpret the flywheel “rotation on engine startup as a ‘knocking’ condition.” If the ECU makes this call, adjusting the fuel/air mix, then it’s possible a stall may occur.
The fix for this problem is a software update from Audi. The automaker will notify owners of the affected vehicles of the problem. The recall is expected to begin on Sept. 29. If you receive a recall notice, contact your dealer to arrange a service visit so that you A3 can have its software updated. The update is free of charge.
