Bring it back. Tell em to f**king sort it out properly or you’ll have a new steed
If it really is losing as much as he says then it has to go back - simples.

My old man had a saying “A swift kick in the bollox often offends but it’s always effective”
I thought this link helped understand the coolant pump arrangement well; see post 9 pics ............... http://www.r1200gs.info/forum/14-maintenance-modifications/30202-coolant-leak.html
Sounds like the OPs system is getting pressurised beyond the norm, although whether the coolant loss is all from the weephole, or via the coolant expansion tank seems unclear. Unless oil contamination is obvious, it might be worth insisting on lab analysis. However, if the dealer can't sort it (insist on seeing the dealer principal) talk to the BMW CS team at Farnborough - the bike must be on their radar already.

Think there should be a "Don't try this at home warning" with this!
Should make the dealer sort it and get proper investigation and explanation as to cause, if you don't know the cause replacing the pump is possibly on treating the system and not the cause so not really a fix. Make sure you don't run out of warranty, as its a historical item get confirmation that any recurrence will be sorted.
Spot on,if your bike is that defective then hand the thing back.You wouldn't put up with that from a car dealer if that was your only form of transport so why stand for it with a bike.Who is the dealer?
My last new GS got through 5 water pumps in 5 months so I rejected it. Send it back. Its a bad un.

Was Benhams but now changed to Rybrook.
I will be calling them and asking them to investigate further at the service which is due in 600 miles. If they find nothing then I will call the BMW CS Team...
Exactly as there is more than enough grounds to claim not fit for purpose!.... A new one is the way forward or thats what I would be asking for considering.
Interestingly, my replacement 2017 spec engine doesn't have the hole, so where does it go then ??

I had a 2016 from new GS TB from Benhams and had 3 water pumps go. Finally all seemed to settle down and when I part x’d the bike at 5500 miles no probs. If I had 6 pumps go I would definitely have lost confidence in the bike by then. And no, you didn’t buy my bike, but it does sound like a bike batch issue?
I believe that its now down underneath the engine.
Somewhere where you can't see it leaking and so don't complain
As far as the rights of the OP goes he can fall back on the sale of goods act and declare the motorcycle as not fit for purpose. How the dealer sorts that out with the OP will depend on the use of the bike and condition since in the ownership of the OP. Expect to either contribute to a same year motorcycle, a straight swap to the same year motorcycle or a good deal on a new one maybe but possible. But the dealer should be fascilitate you a good deal since you have had repeated issues with the water pump, this being a critical component of the engine.
I would however be interested in what permanent solution they may found if any. There must be some fault in the cooling system to loose that much in 600 miles. I'm speculating that the pump weeps are normal, the traces of coolant left on the engine case. As mentioned before but not sure of how it would happen on the LC engine is that coolant gets burned off in the cylinder. VW Golf 5 2.0 TDI engines suffered the same fate fixed by a new head and gasket. I'm very much convinced 5 pumps cannot be defective, that is too high a number and the techs should have been looking elsewhere to find fault. Any internal leaks would contaminate the oil so it either gets burned off or dumped overboard. Ask them to have a look and determine where the coolant leak is. This might support your rejection of the bike or the claim for a new engine. I suspect they will offer the latter.

On most waterpumps there is a hole between the two bearings. When the seal goes coolant passes through the inner bearing and leaks out through the hole. This is to let you know that the seal is leaking. If there was not a hole the grease would get washed out of the bearings and when the bearings packed up the water would pour out.

Ask the dealer to pressure test the cooling system. It’s what we do in the trade to look for coolant leaks. Obviously you know the water pump is leaking, but where else is going and why?
