Or until there is an actual problem.
I am not mechanically inclined in the least, so my question may be a dumb one, but here is my thought: it is very common for a pump to whine between turning on the ignition/starter switch in this case and when the bike fires up, the whine goes away. Does that mean that the pump goes into a lower “run” mode, not necessitating the “start” mode and running at full speed? In this case, the pump never stops whining. Does that mean it never slows down to this “run” mode and could be subject to burning out prematurely? This stated gradually for me, but is now Omni-present every single time I ride. Annoying at start up, then I cannot hear it while riding due to engine and wind noise. Let’s say the first stretch of riding is 20 minutes without a stop, then Bamn, first highway exit or stop light and the whining becomes noticeable again. Takes some of the joy of the ride away fairly quickly. Lots of miles in Michigan in-between BMW dealers, so a few hours realistically could turn into a day or more (towing the bike, hoping they are open, hoping they have the R18 pump, etc). Again, sorry for my potentially dumb questions, but my novice head tells me the pump is never slowing down after starting the bike.
I cannot speak for this model's fuel pump characteristics (more about that pesky missing shop service manual elsewhere in this forum) but my experience is that although some vary in speed proportionate to demand MOST run at a constant speed to simply maintain a constant pressure. Typically you hear the pump most on start up and that sound dies down once all paths are at pressure. Also typically is that as they age and/or become contaminated they tend to get noisier - but I don't think any of us are "there" yet. Some electric motors will be quiet when cold and begin to "whine" when fully warmed up and still be fully functional and reliable - just louder than others (like some of us are). I don't think the mother ship actually builds these pumps (Hell they can't even get accessories made by others out to us) and my best guess is there are pumps in our tanks of identical performance specs made by various manufacturers, and some are simply noisier than others.

Could you relay the German link on this forum ???
English: Any information about a recall?It seems that this video has already had its effect: I just had a call from the dealer to tell me that the problem was the subject of a "puma measure" (?) Which consists of changing the pump and making a software update. Except that he tells me that my bike already had this procedure, obviously without any success!
They must contact me again to tell me if they find another solution ...
All the videos had been updated with this info.
