TÜV – significant defect headlight cleaning system

Hello! I just saw that the TÜV rated the lack of my headlight cleaning system (wiper arms) as a considerable lack! I thought it was only Xenon and LED so!? The joke is that I’ve been driving for over 6 years without. 3 past tests without this complaint. Why did he do that? Now the problem is that I have mounted both arms again and see there… right / passenger doesn’t work anymore, or twitches only once and is stuck. The spare part is so no longer available and I pay, if available again at Skandix, certainly not 250€ for such an useless gimmick! I don’t want to buy this anyway, because first of all I can’t find it, only abroad… and secondly a 25 year old electric engine from abroad?!! Neee… Volvo 8628288 So what do!?
