hello together, how long did your stand-up heating last until it had a defective one for the first time and how often did you use it to date ?? i have bought a used V70II since juli 2009 (at that time 111,000 km) and always use the heating for the first motor start as soon as it gets cold, like now. previous owner had no unlocking of the SH. middle of the year I had a total failure of the SH, everything was completely renewed, cost: 600,-€ alex
