Well, if it blows the hose- it means the pressure exceeded the hose rating - which, I hope, is more than the operating pressure of 19 bar. So I assume it blows because the pump doesn't stop at 19 bar.
Clan, you know that I love Volvos- love the cars, love the brand, love their philosophy in general. But hybrid powertrains have existed loooong before PP was invented- even mild hybrids are older than PP. Volvo introduced PP - and after a 3 yr run- they went mainstream, discontinued the air pump and went hybrid- like virtually all other car manufacturers.. Reminds me of the infamous VW G-ladder saga..
