Replaced it with the original that I took out and no leak. Now I have to do the job again at 200K, but at 160K the original BMW one is still running strong.
At 160K, the original Wp lives on borrowed time!

Bosch strength is in sprak plugs, ECU etc. Now they get into the Water Pump market, it is another story.

For Water Pump, I have had HEPU now for 4 years, zero problems. Volvo people use HEPU alot and rock solid. My recommendation is do a cooling overhaul at 160K and change anything in there that is OEM.
