If the rear windshield washer on your Audi A4 Avant isn't working, it could be due to a blocked nozzle, a malfunctioning washer pump, or a leak in the hoses. Your first step should be to check the fluid level to ensure there is enough. Then, activate the washer and listen for the pump - if it's running, the issue is likely a clog or damaged hose. A potential problem could also be related to the wiring, so inspect the wiring harness for any damage or shorts. Repair costs will vary, with a replacement part priced between $50 and $75 depending on whether it's aftermarket or OEM.
If the rear wiper fluid isn't functioning in your Audi A4, it's probably because the nozzle is blocked, the pump has stopped working, or there is a leak present.
