The most expensive known risk is turbo wastegate actuator wear (boost faults, limp mode): it usually appears at 80,000–200,000 km and costs €300–1,800 to fix.
✓ The faults of this engine were checked against sources (10/2026). Each item has at least two independent sources or an official recall or parts-maker technical note.
Signs: Coolant loss, coolant smell, fluctuating temperature gauge, slow warm-up or overheating warning
Fix: Find the leak with UV dye or a pressure test; replace the pump and thermostat module as one unit
Signs: Whistle or hiss at idle, rough idle, lean codes (P0171), higher oil use, oil leaks at seals
Fix: Check fuel trims in live data; replace the PCV valve / oil separator
Signs: Power loss, boost pressure codes (e.g. P0299), limp mode
Fix: Compare set and actual boost in live data to rule out leaks; repair or replace the actuator, or the turbo if the wastegate itself is worn
Signs: Clunk over bumps or when turning, car sits lower on one corner, bouncy ride; broken spring or leaking damper found at inspection.
Fix: Replace broken springs and worn dampers in pairs per axle; on cars with adaptive dampers check the damper codes too.
Signs: Knocking over bumps, vague or nervous steering, uneven tyre wear; play in the axle mountings at inspection.
Fix: Replace the worn arms of the five-link front axle (usually in sets per side) and align the wheels.
Signs: MMI freezes or reboots, Bluetooth/CarPlay will not connect, Virtual Cockpit flickers; Pre Sense brakes for no reason or reports a fault.
Fix: Have the dealer install the latest MMI and assist software and recalibrate the front camera; check battery condition first, as low voltage causes many such faults.
Signs: Aluminium B&O speaker trim strip lifts or peels off the door panel and exposes sharp edges.
Fix: Check the VIN with an Audi dealer; the trims on all four doors are replaced free of charge.
Signs: No warning; the towball may not lock properly and the trailer can come loose.
Fix: Check the VIN with an Audi dealer; the swivel mechanism is inspected and the module replaced if from the affected batch.
Signs: No warning signs; in a crash an airbag or belt tensioner may not work as intended.
Fix: Check the VIN with an Audi dealer; affected airbags and belt tensioners are replaced free of charge.
Signs: Slipping, high bite point
Fix: Replace clutch kit
Signs: Rattle at idle, vibration pulling away
Fix: Replace with clutch
Signs: Gearbox warning, odd or even gears (1-3-5 or 2-4-R) drop out, delayed or wrong shifts, limp mode or no drive
Fix: Diagnose with a dealer-level tester; repair the control unit / solenoids or fit a reconditioned mechatronic unit, change the oil and filter and run the adaptations
Signs: Knock or jerk when shifting down into 3rd or 2nd in traffic, a pause of 1-3 seconds before the car pulls away
Fix: Ask the dealer for the latest gearbox software, change the oil and filter and reset the adaptations; if it persists, have the mechatronic checked
Signs: Delayed or harsh shifts
Fix: Fluid service, repair
