Audi Q2 Washer Pump Failure With Headlight Link

The washer system issue you describe matches what I encountered with my Audi Q5 2020 diesel. The silent pump usually indicates an electrical fault rather than a fluid system clog or leak. In my case, the problem traced back to a corroded cable connection at the washer pump, which also affected the headlight cleaning system since they share the same pump and electrical circuit. The xenon headlight washers use significant power, which can accelerate connector wear. The repair involved: Testing pump functionality with direct power, Replacing damaged wiring connector, Checking system hose integrity, Verifying pump relay operation This is not typically a serious repair but requires proper diagnosis to avoid replacing parts unnecessarily. The washer system fault often triggers when the electrical connection fails rather than the pump itself being defective. Worth checking the fuse first, but given both front and headlight systems are affected, its likely the pump connection or relay. These components are prone to corrosion from fluid exposure over time.

Thanks for the detailed response on the washer system fault. The explanation about the electrical connection makes sense, especially since both front and headlight cleaning systems stopped working simultaneously. Did you recall the repair cost? My local shop quoted 350 Euro just for diagnostics. Also curious if you experienced any related issues since the repair, particularly with the xenon headlight cleaning system? Been hesitant about repairs since my last garage visit, but your explanation gives me a good starting point for discussing the problem with a mechanic.

Glad I could help with the washer system diagnosis. Just got my car back from the mechanic last week, and I can confirm the headlight cleaning system works perfectly now. The repair was much cheaper than your quote, only 165 Euro total for fixing the corroded cable connection and faulty relay. The malfunction turned out to be exactly what I suspected, the electrical connection to the pump had deteriorated. No leaks or other issues were found. The xenon headlight cleaning system now activates reliably every time, just like when the car was new. Looking back, its good I got it fixed promptly since these electrical issues can sometimes lead to more expensive repairs if left unchecked. Consider getting a second opinion if that diagnostic fee seems steep, the actual repair is usually straightforward once the fault is properly identified. My system has been working flawlessly since the fix, with both washer and headlight cleaning functions operating as designed.

Going to the mechanic today finally solved my washer system problems. Took your advice about the electrical connections and showed them your explanation. Turns out you were spot on, it was a corroded wire connection to the pump. The repair was reasonable at 190 Euro, much better than the initial quote I got. They found the malfunction was caused by water seepage around the pump connector. Once they replaced the wiring and sealed it properly, both the washer and headlight cleaning systems started working perfectly. The mechanic mentioned these faults are pretty common, especially with the shared pump setup. Looking back, I worried too much about potential major repairs. The whole job took less than 2 hours, and they even showed me the damaged parts. Great to have both systems working again, no more dirty windshield or headlights. Really appreciate the guidance which helped me approach the repair with better understanding.
