One cause could be a bad expansion tank cap. Swapped the old one back.



That was it. No more deflated hose.



The cap, mahle behr, was bad. The old cap is uro.



So, watch out for bad bits even when buying quality parts.
Which MAHLE/ BEHR cap did you have this issue with? I have a few different versions that I purchased. There are 2 with a fully black cap and and orange underside where it shows the 200 one made in the united kingdom and one made in Austria and the "PREMIUM LINE" cap that has the colorful images on the top of the cap that also says Made in Austria. For some reason my Tapatalk app is having issues uploading images.
