Greetings, I'm a brand new member to BMW RA. One of the reasons I joined was because I looked at a couple of OTL magazines at my dealership while getting service work done. I found it to be an impressive publication. My water pump went bad on my 14 GSLC. While reading OTL I saw an article about a review of sorts on the LC (I think it was a GS but can't remember.) Long story short, the author also had a water pump replaced under warranty. He mentioned that he discovered that the part number on the new water pump was different than the old one as it had an improved o-ring type seal. Does this ring a bell to anyone? I looked at the online OTL issues and can't find it. It's possible it was a little older of an issue. I'm trying to confirm regarding a new part number on replacement water pumps.
