Owner reviews for water pump

i have a VDO water pump. its been in there 7+ years and has been working fine so far.

I bought the continental from RockAuto a ways back, zero issues and great quality.

When you do get a pump, buy the entire pump (front and back hemisphere) (like a GRAF brand). If this engine has been moving grit, the rear half of the water pump will be worn more open and not be able to move fluid efficiently.

I used the gates kit from rock auto including the gates water pump… Car seems to be driving fine for the past few thousand miles since install.

It’s still baffles me how BMW can’t get a quality water pump on its vehicles.

There was only a slight oil residue on top of old water pump and none inside or near the pumps gaskets. No cracks in the plastic housing were found anywhere on the old pump.

I had mine done on my 2018 S4 from an Audi dealer in PA. Cost me $3,928 total. They replaced the water pump and hoses, coolant regulating valve, vacuum control valves and lines, and the serpentine valve. The water pump is what failed and took everything else with it.

Mines literally the same story as yours. It’s leaking out the weephole after about a month, less than 1500kms install. Their warranty claim procedure looks as complicated as it can get too

It’s a garbage unit, mine started to weep out from the hole after less than 1500kms. Warranty claim seems extra complicated to deter people from using it too

Well, all of these seals are not created equal in my experience. I have had a bad experience with some seal kits that had combustion chamber seals that were really hard so they didn't stretch evenly over the injector or compress properly with the proper tools. Luckily I was able to source some of the correct ones from a tech friend the same day, so I was able to get my car going. You really need to make sure that you have the right ones, as you have to destroy the old ones to remove them, and if the new ones aren't right, you are screwed. I personally won't recommend anything other than factory parts, as too many times I have tried something else, like Graf aluminum water pumps (two failures-100%, within six months) and gotten burned.
