Hello, I recently had my vehicle for rim preparation (again a completely different story). Theme 1: When I was on my way home after pick-up (all tyres hit 3.5 bar – normal would be 2.1-2,4), suddenly the tyre pressure control light went on. Left back no signal any more. I contacted the workshop from home to find out if something had been noticed during the rim repair. The answer first made me a little speechless: “Yes, we did after the tire repair. end assembly saw that the sensor was broken. But I thought that was already it. We did not dismantle it during the work, but just glued it on and had the tire re-assembled at the end.” Question: I took a photo of the amaturation board in the workshop when the vehicle was handed over … still without an error message. Would the workshop have had to inform me? What requirements can I assert, especially since I have the extra effort to dismantle the tire just again and Topic 2: If you have changed a tyre, whether in the workshop or at home, it is necessary to fold the wheel nut again after a certain driving distance. Unfortunately, this has failed with me because I have not even got my nut set at all. The wheel nuts have/had SW21 6-kant. I have always taken a 13/16″ nut (approx.20,6 mm) so far; it has fit “absorbent”. Also a newly bought wheel nut does not fit. The nut (picture in the appendix) was then given to me after an increasingly unfriendly conversation. For me, this is a 6-spline and completely unsuitable for a 6-kant nut. Question: Would the workshop have had to point out the use of this tool, because perhaps the correct one was no longer suitable at the beginning of the repair? Who now comes for the cost of a new tool? n Set of wheel nuts on? Cost 20x approx. 11 $/h plus shipping, inch, VAT Sorry for the essay and thank you very much for your advice in advance.
