Hello, I’m about to get the Tüv and have a few questions about it. 1. The tyres are slightly expired inside (almost blank), but on the main surface (where the lock pointer is) there is still 2 mm on it. Is there any problem? 2. The brake pads at the front still have 3mm covering, the battery wear indicator has not yet addressed. However, braking performance is not limited. Is there any problem? 3. Have my axle carrier preserved with cavity wax, but it was necessary to put it on two positions. 10mm to drill the extinguisher to introduce the spray probe. The extinguishers have been drilled at the lower area and are now used as a water flow. Is there no place where particularly many forces work on the material. Did you learn from a known only afterwards that one “actually” must not drill on the axle carrier. Does the problem, or do they allow the argument with the water flow? Basically, I would not drive into the clock because of the things with the tires and coverings now, but Pro fil and covering is still available and I hate to change what is still good. Thanks for the answers already.
