hello fangemeinde, my elch I bought used in dez.2020 – accident-free from 1st hand. cautiously “dicked in”, as he already indicated 362 ́km on the clock. so I did not notice strong wind noises and a bright whistle from 120km/h. today a test drive up to approx. 180km/h. had thought the sliding roof and the cut with adhesive tape glued tightly – the bright whistle is gone. only from 120km/h on very strong disturbing wind noises can be heard. sub sub I have the impression that these are created on the side of the passenger. all door and window seals are as new, the ventilation nozzles were closed during the test. the “solar protection roof” under the sliding roof does not bring any changes. who has an idea where these sounds could come from and how I get them away.
