Hello guys, we have a BMW 750i, built in 2016, G11 model. The vehicle had problems with cooling water loss for a long time and we had to refill again and again. A mechanic at the time said that it could be on the thermostat, so we had it replaced. After that the loss was less, but the problem was not completely solved. When we were traveling abroad, the vehicle suddenly lost much cooling water. A mechanic on site found that a cooling system The problem: you couldn’t find the original hose there. That’s why the mechanic improvised and installed some hose so that we could continue. It was a mess work, but it worked for the first time. Now I’m facing the problem that I don’t have the original part number of the two hoses. We unfortunately threw away the defective hose at the time, and I didn’t yell at the number. ben. I found a video on the internet and took a picture of it – you can see the two hoses I need. I upload the picture here. Maybe one of you has the same vehicle (BMW 750i G11) and could you see which part numbers are on the two hoses? On the one tube should be a number with “1-” and on the other one with “2-“. Thank you for your help!
