WHILE DRIVING APPROACHING A STOPLIGHT, I RECEIVED A "GEARBOX MALFUNCTION. OK TO CONTINUE DRIVING WITH LIMITED FUNCTIONALITY" ERROR.

WHILE DRIVING IN TRAFFIC, MY CAR DROPPED INTO LOWER GEARS AND STOPPED MOVING, AND TWO ERROR CODES POPPED UP "GEARBOX MALFUNCTION" AND "TPMS MALFUNCTION". LOOKING THIS UP ONLINE AND DISCUSSING WITH MY MECHANIC, THIS IS SOMETHING HAPPENING IN A LOT OF THE CARS THAT ARE THIS MAKE & MODEL AND HAVE THE SAME TRANSMISSION.

IN SOME CASES, THIS LOSS OF POWER CAN MAKE THINGS DIFFICULT TO PULL OVER SAFELY, AS THE STALL CAN HAPPEN IN AN I…
Common questions
How serious is the powertrain problem on the 2012 audi S4?
It's a documented issue but not catastrophic. 14 complaints have been filed. Repairs average $2,500 and most owners catch it before it causes a breakdown.
At what mileage does the powertrain typically fail?
Mileage data is limited for this issue. Owners report failures across a wide range, suggesting cause is more about driving conditions and maintenance than mileage alone.
What does it cost to fix?
Independent shops typically charge around $2,500 for powertrain repairs on this vehicle. Dealer pricing tends to run 20-40% higher. The exact figure depends on the specific failure mode, parts availability, and your local labor rates. If you're outside factory warranty, an extended service contract often covers this category.
Are there any recalls related to powertrain?
No active recalls currently cover powertrain issues on this vehicle. The complaints filed represent owner-reported failures that haven't risen to the level of a manufacturer-issued recall — but they're still worth knowing about before you buy or budget for repairs.
Complaint and recall data sourced from the National Highway Traffic Safety Administration (NHTSA)
public records database. Severity ratings are derived from reported crashes, fires, injuries, and fatalities.
