Du hadde på tenning ,hakk 2 ,når du åpnet SP luftenippelen?I finally got around to (try to) renew the brake fluid on the 036 myself last night, and read up on this how-to first. Weirdly I also had a really hard time loosening the SP-valve, even though I opened it without any problems last year (and bled fluid from it). When I finally got it open (had to carefully removed the blue protective cap to fit proper tools on there), there was no fluid coming out of it - no pressure, no nothing! I have a current ASR-fault which I am hoping to clear after renewing the brake fluid, but now I’m starting to wonder if the system has been bled wrong somewhen in the past which is causing it (or has damaged the pressure valve of the ASR-system)..
Due to unforeseen issues (dinner) I wasn’t able to finish the job yesterday evening, but will keep searching for causes today. I can activate the pre charge pump manually using HHT-WIN, and will try to do so today and see if there is any fluid coming out of the SP-valve when doing so.
