That would make sense why my steering was incredibly heavy after I left the garage.
Unless they were mistakenly reading in bar and somehow converted to psi, rather than reading actual units, I reckon they had a really bad day.
41 psi if read as 4.1 bar = ~60 psi.
Only explanation I can think of, unless their gauge had blown, and everyone had 'wrong' pressures yesterday.
