Adam Headlight Washer Problem

Hmm, strange one. When you say 'headlight cleaning system' do you have Xenon or LED headlights? Some models didn't have the cleaning system at all unless you had the upgraded lights. If you DO have the washers, check for any obvious leaks around the pump area. Could be a split hose.

Yeah, they're Xenon lights, so definitely should have the washers. I'll have a look for leaks tomorrow when it's light. If there aren't any leaks, what else could it be?

Okay, Xenons narrows it down. No leaks, eh? Then it's likely the pump itself or a dodgy relay. Honestly, chasing electrical gremlins can be a pain. Might be worth getting a workshop to take a peek before you spend ages on it.

Cheers. I took your advice and went to a local garage. Turns out a cable connection to the pump was corroded. They cleaned it up and replaced a relay. Cost me 165€, but at least it's sorted!
