2022 Audi A5

The 2.0L EA888 Evo4 engine in the A5 uses an electronic diverter valve (also called a bypass valve) on the turbocharger that can fail. When the diverter valve sticks open, the engine loses boost pressure, resulting in significant power loss. When it sticks closed, compressor surge occurs, producing a fluttering or chattering sound. A check engine light with boost pressure underperformance codes (P0299) is common.

Dealer replaces the electronic diverter valve. Updated valves with improved solenoid actuators are available. The turbocharger charge pipes should be inspected for cracks or loose connections that can mimic diverter valve symptoms. Reference Audi TSB 2041276/2 for boost system diagnosis.

The DL382 7-speed S-Tronic transmission in the A5 can develop solenoid failures within the mechatronic unit, causing intermittent harsh shifting, delayed gear engagement, and occasional limp-mode activation (the transmission locks into a single gear). Warning messages appear on the driver information display, and the vehicle may need to be restarted to temporarily clear the condition.

Dealer diagnoses the mechatronic unit using VAS diagnostic equipment and replaces the failed solenoid(s) or the entire mechatronic unit if multiple solenoids are affected. The transmission fluid and filter should be changed simultaneously. Reference Audi TSB 2046783/2 for S-Tronic mechatronic diagnosis.

A5 Cabriolet models with the power-folding soft top can develop hydraulic fluid leaks in the convertible top system. The hydraulic cylinders, lines, and pump assembly age and develop seepage, causing the top to operate slowly, stop mid-cycle, or display 'Roof Malfunction' warnings. In some cases, the roof gets stuck in a partially open position, leaving the cabin exposed to weather.

Dealer identifies and replaces the leaking hydraulic components — commonly the lift cylinders or hydraulic pump. The hydraulic fluid is refilled and the system bled. The convertible top sensors and microswitches should be recalibrated after any hydraulic repair. Reference Audi TSB 2050843/1 for convertible top hydraulic diagnosis.

The Audi pre-sense front collision avoidance system can generate false forward collision warnings and autonomously apply the brakes when no obstacle is present. These phantom braking events are triggered by overpasses, road signs, shadows, and vehicles in adjacent lanes. The sudden braking can startle passengers and creates a risk of being rear-ended by following traffic.

Dealer recalibrates the front-facing camera and radar sensor. Software updates to the driver assistance control module improve object detection algorithms and reduce false positives. Reference Audi TSB 2053187/1 for pre-sense system calibration. The pre-sense sensitivity can be adjusted in the MMI settings.

The front lower control arm bushings on the A5 can deteriorate prematurely, causing a clunking noise over bumps, vague steering feel, and uneven front tire wear. The rubber bushings crack and separate from the metal sleeves, allowing excessive play in the front suspension. The issue is more common on vehicles driven on rough road surfaces and in cold climates.

Dealer replaces the front lower control arms with new bushings (the bushings are not separately serviceable — the entire arm must be replaced). Both sides should be done simultaneously. A four-wheel alignment is mandatory after control arm replacement. Updated control arms with stiffer bushings are available.

Volkswagen Group of America, Inc. (Audi) is recalling certain 2021-2022 AUDI A8, A6 Allroad, E-TRON Quattro, 2022 S3, RSQ8, RS7, RS6 Avant, Q8, Q7, Q3, E-TRON Sportback Quattro, S5 Cabriolet, E-TRON GT, S5 Sportback, A7, A6, A5 Sportback, A5 Cabriolet, A4, A4 Allroad, A3, S8, SQ7, SQ8, S6, and S4 vehicles. The infotainment main unit may become damaged internally when the vehicle is shut off, resulting in an inoperative rearview camera display the next time the vehicle is started. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 111, "Rear Visibility."

An inoperative rearview camera display reduces the driver's rear visibility, increasing the risk of a crash.

Dealers will replace the infotainment main unit, free of charge. Owner notification letters were mailed June 6, 2022. Owners may contact Audi's customer service at 1-800-253-2834. Audi's number for this recall is 91Ei.

Volkswagen Group of America, Inc. (Audi) is recalling certain 2021 Audi A8 and S8, 2022 Audi A5 Sportback, A4 Sedan, E-Tron GT, Q3, Q5, RS6 Avant, A3 Sedan, S5 Sportback, Q5 Sportback, Q7, Q8, RSQ8, SQ7, SQ8, and S3 Sedan vehicles. A software error may prevent the rear-view image from initially displaying when the vehicle begins to reverse. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 111, "Rear Visibility."

A rear-view camera that does not display an image reduces the driver's rear view, increasing the risk of a crash.

Dealers will update the infotainment unit parameters, free of charge. Owner notification letters were mailed November 9, 2021. Owners may contact Audi customer service at 1-800-253-2834. Audi's number for this recall is 91CR.
