Q3's rear wiper can be turned off by: turning off the ignition switch and pushing the wiper switch downward. The wiper, also known as the windshield wiper, is a device used to wipe off raindrops and dust attached to the vehicle's windshield, improving the driver's visibility and increasing driving safety. The Audi Q3 has a body length, width, and height of 4481mm, 1848mm, and 1616mm respectively, with a wheelbase of 2680mm. It is equipped with a 1.4L turbocharged engine, with a maximum horsepower of 150ps, a maximum power of 110kw, and a maximum torque of 250nm, matched with a 7-speed dual-clutch transmission.

I also figured this out when I was driving an Q3 before! Its rear wiper switch is actually hidden on the button with the wiper symbol at the end of the right-hand stalk. Normally, pushing the stalk forward sprays washer fluid + activates the front wiper, but the rear wiper requires pressing the end button separately: a short press activates intermittent wiping, another press changes it to continuous wiping, and a third press turns it off completely. Don't panic if the rear wiper automatically activates when reversing—this is the default setting, and it stops by itself when you shift back to D. If you can't turn it off no matter what, remember to check behind the steering wheel to see if you accidentally switched to the front intermittent wiper position—this setting automatically triggers the rear wiper linkage. If all else fails, just turn off the engine and restart it; electronic systems can occasionally act up.

Just taught my wife how to turn off the rear wiper on the Q3 a couple of days ago. While driving with the right hand, simply use the thumb to locate the square button at the outermost end of the wiper stalk—it makes a clicking sound when pressed. Pressing it once shows a water droplet icon for the rear window on the display, indicating intermittent wiping. Pressing it a second time changes the icon to solid, meaning continuous wiping. Pressing it a third time, with no icon displayed, means it's truly off. To spray water on the rear window, push the entire stalk all the way toward the dashboard and release—it will automatically spring back. Important reminder for brothers using auto-sensing wipers: as long as the front wipers are in continuous mode, the rear wiper will also work. To turn off the rear wiper, you must first switch the front wipers to manual mode.

Last year, while driving the Q3 into Tibet during a heavy rainstorm, I finally figured out the rear wiper logic. The control core is the square button at the top of the right-hand stalk on the steering wheel, which requires a deeper press than regular buttons. Actually, designed the front and rear wiper settings with a counterintuitive linkage: if you adjust the front wiper frequency by turning the stalk, the rear wiper speed will automatically sync. To turn off the rear wiper separately, you must press the end button multiple times until all indicator lights are off. If the wipers go crazy, first check if the yellow rear window icon is lit on the center screen—holding the end button for ten seconds can force a reset. If they suddenly activate in a tunnel, it’s likely the reversing camera linkage was triggered.

As a decade-long technician, I remind you of two key points: First, don't be confused by the steering wheel stalk – the rear wiper's independent switch is on that rubber button at the end of the stalk. Second, remember the rear wiper cycles through three states. Focus on checking if the button is stuck, as spring tree sap can easily glue it and cause accidental activation. Be extra careful during car washes – direct foam gun impact on the button may cause malfunction. For post-2018 touchscreen models, additional steps are needed: After turning it off, you must uncheck 'Auto wipe when reversing' in the central control's 'Vehicle Settings → Mirrors & Wipers', otherwise the wiper will always activate when reversing.

If the button doesn't respond, here's a mechanical shutdown method: Open the rear tailgate directly, flip open the right-side interior trim panel, and you'll find a black square box labeled with a VWAG tag - that's the wiper motor. Unplug the connector immediately for silence, and remember to wrap the connector to prevent short circuits (for emergency use only). If the rear wiper remains inactive for an extended period, remember to remove the rubber blade; otherwise, it may freeze in winter and burn out the motor if forced to operate. The Q3 wiper size is special, with OEM rubber blades featuring a self-locking clip design—avoid pulling forcefully when replacing them yourself. If water stains remain after using the rear wiper in the rain, spray alcohol-containing windshield washer fluid several times to dissolve the oily film.
