    Jet nozzle not spraying correctly

    Our Tiguan's jet nozzle is no longer spraying as it should. It sprays a single jet, no longer flat. I tried cleaning it by poking toothpick inside but no go.

    Please tell me how to replace them and where I can buy parts from.

    Thanks so much! Happy motoring

    As above, this happened on my Golf GTI a few years ago. I removed the jets, soaked them in soapy water for a few hours to help loosen any debris, then blast them out with some compressed air (or you can blow air with your mouth into them if you do not have an air compressor). They worked fine again after that.

    They block up over time with scale which leads to partially blocking off the outlet.

    If you cant be bothered doing this, at least try a very thin needle (like from a sewing kit) to unblock the jets. A toothpick is far too big to fit into the jet nozzle properly.

    They unclip from the underside of the bonnet.

    Refer to this document (right near the bottom of the page): Volkswagen Tiguan Service and Repair Manual - Windshield Washer System - Windshield Wiper/Washer System

    I presume harder water areas may have this issue more so than soft water areas?

    Yes. I do use washer fluid but any tips welcome

    Although I had a Polo with the same jets for over 5 years and zero issues

    Demineralised water would probably be the best water to use along with a good quality windscreen water additive, as I can only assume that hard water in some areas would make it more likely to block up over time with mineral deposits.
