What the fix does
This page covers 3 recalls and 25 owner complaints for the 2015 Audi A4 Allroad.
On the 2015 Audi A4 Allroad, engine and powertrain complaints make up the largest share of owner reports, with steering close behind. On the engine side, owners report issues with the turbocharger cooling pump failing, specifically the auxiliary pump that runs after shutdown to cool the turbo, with some describing extended waits for replacement parts. Powertrain reports include concerns about unintended acceleration and a rolling-forward behavior when the transmission is shifted into reverse on a downhill grade. Steering complaints describe the wheel becoming progressively harder to turn, with at least one owner reporting that the difficulty became severe enough to make highway cornering a real struggle before the car would respond.

By System
The 2015 Audi A4 Allroad has 3 recalls, all carrying fire risk: the electric coolant pump can overheat or short-circuit, and a separate wiring issue in the auxiliary heater circuit can cause wires to melt.
All three recalls center on fire risk from two different sources in the engine and electrical systems. The 2.0L turbocharged engine uses an electric coolant pump to manage engine temperature, and debris from within the cooling system can block that pump. A blocked pump can overheat on its own, and in some cases the pump can also short-circuit internally. Either condition can generate enough heat to start a fire under the hood. The auxiliary heater has its own concern: corrosion can develop inside the electrical connector that supplies power to the heater, causing resistance to build up in that connection. That resistance generates heat, which can cause the wiring to overheat and melt, again raising the risk of fire. Both issues are confined to vehicles with the 2.0L turbocharged engine and the auxiliary heater equipment, and owners should confirm their vehicle's VIN is covered before arranging a repair.
