Headlight cleaning system of the 2018 BMW 5 Series Diesel does not work

Hey, I had a similar problem to yours with my 2015 BMW 3 Series. In the end, it was the headlight washer pump, which was already pretty worn out. The thing is, these parts don't last forever and have to be replaced after a while. You should pay close attention to this the next time you visit the garage. If the problem is deeper, a complete check of the headlight cleaning system would be necessary. Honestly, this was already a serious problem, without a functioning headlight cleaning system, the headlights could lose a lot of their brightness in bad weather. So don't take this lightly under any circumstances. Good luck, hopefully it's not that bad for you.

Hi, thanks for your advice! I noticed that my BMW 5 Series has the same problem. So the headlight washer pump was the culprit for you, huh? Do you remember how much the repair cost and whether any other problems have arisen since then? I would be really grateful for any information. It helps to prepare for the next visit to the garage. Hopefully it's not as bad for me as it was for you. Thanks again!

Hey, no problem! Yes exactly, the headlight washer pump was the culprit in my 3 Series. But since I've been to the mechanic, everything has been fine. As for the rear window wiper pump signal error that you have in your BMW 5 Series, that was fixed for me too. The cost of repairing the cable connection of the pump or the defective relay was €165. Admittedly, that's not a lot of money, but it was really necessary. I hope this helps you a bit to plan everything for your next workshop visit. Good luck and hopefully your bill won't be as high as mine!

Thanks guys for your detailed answers and advice! I will ask the mechanic to check the headlight washer pump on my next visit. Hopefully that will be the problem and we won't have to overhaul the whole system. It was very helpful to know what costs I might be facing. With any luck I'll be better off than you. I'll keep you posted after my workshop visit. Thanks again for your help and wish me luck!
