FAV making noise but not letting fluid pass
Hi,
after my car was not driven for app. 5 months, the HFS-3 shows an error. I checked the nozzle, works fine, and the pump works as well. There is pressure before the FAV, but the hose after the FAV is dry. The FAV makes noise, so I guess the valve works but is somehow clogged. Can it be cleaned or repaired somehow, or do I need a new one? Thank you! Regards Stefan

Re: FAV making noise but not letting fluid pass
When I disassembled it, I found that the small sieve inside is clogged.
I will try to clean it, but I have no idea where the contamination came from. Regards, Stefan B. Last edited by sbrunthaler; 19-06-2023 at 01:00 PM.

Cleaned it, put everything together, and now the flow is fine.
But the pump head has a small crack, so I need a spare part. Always empty the system for cold periods if you park the car over winter... Regards, Stefan B.
