Peugeot 4007 Headlight Washer Issue

Hey, I've got a 4007 too. Sounds familiar. Did you check the cable connections to the pump? Or the relay? Could be a defective connection. Is your car equipped with Xenon headlights by any chance?

Cable connections, eh? Where exactly are those located? And yeah, it has Xenon lights. Does that make a difference?

The pump is usually near the washer fluid reservoir. And yes, the Xenon headlights are important because they require a cleaning system. If the connections are fine, it could also be a leak in the system somewhere. Honestly, I'd take it to a workshop. These things can be a pain to diagnose without proper tools.

Thanks for the insight! I took your advice and went to a local workshop. Turns out it was a defective cable connection, just like you suspected. Repair cost me 165€. All sorted now!
