Good evening morning I have to sit down to the Swedish TüV. I have to do a construction site tomorrow, exchange the rear wheel bearings due to missing signal. At the same time I also make the brake calipers new, if I have the Sch**ss apart. I have read out today, not Vida and have still two other construction sites on the paper however not relevant for the acceptance. 1. Sirene alarm system communication error 2. Air quality sensor internet error. already someone and knows an inexpensive solution? I have invested more than 4000€ in the moose since the purchase in August at a purchase price of 3990€. Slowly I run out of air. The dealer had written fresh waiting. ??
