Hello, I own Volvo V70 Kombi year of construction 99 with approx. 175,000 KM mileage. Since I intend to drive the car even longer, I am thinking of renovating the shock absorbers completely round. I already had the damping level of the shock absorbers tested by TüV: VA left 72, right 68, HA left 65 and right 74%. According to TüV, the limit value is 60%. At the HA left a little oil run out of the shock absorber is to be determined, whereas at the last HAU on the part of TüV this was not criticized for anything. The TüV-Mensch had only noticed the somewhat too big performance difference of the HA shock absorbers during this test. I was primarily concerned with the rear shock absorbers, which with my model are also with automatic level control, whose acquisition is unfortunately quite expensive. The problem with the retrofitting on normal gas pressure was already discussed in detail in the forum (great praise to all the useful information!). My question would now be whether it was with the installation of the 12th gas shock absorber, which would not have been used in the first place, but to increase the load of the load.
