Water pump GRAF or Pierburg

GRAF makes this particular pump without the magnetic impeller, and it’s the best option.

The all metal pierburg water pumps last longer than the plastic ones.

I'd recommend looking at an upgraded Pierburg water pump. None of the plastic bits & will save you from replacing it again in a few years.

Have installed many pierburg Full alum cast pumps as well with good results. The Pierburgs are made in china FYI

Graf is good. They are an OEM (original equipment manufacturer)

I run a Graf pump myself for about 2 months now and it's working fine so far.

New parts should be in tomorrow (Pierburg pump). I'll update again after everything is back in! As a small detail, I noticed a brown seal-looking thing stuck in the impeller of the water pump (Continental, BMW logo. Probably factory) I am thinking the pump internally failed while spinning, and the internals took the hit and self-destructed. Hence the total BSD failure code. Just a guess though.

I would get a vdo/continental water pump. I’ve bought the all aluminum water pump from pierburg and it died in about 800 miles.

I picked the pierburg for all aluminum casing and impeller. They were both about the same price last time I needed to get one. Note that the pierburg failed at not even 10k miles. I replaced with another pierburg chalking it up to bad luck. The only advantage I can think of with the pierburg is the fact that you can torque down the hoses that use clamps and not have to worry about cracking the housing. But in reality doubtful that is a risk. Also it won’t be in service long enough to get brittle enough to matter.

Yeah... That Graf pump did not work out... Had to remove Graf pump and get the proper pump from local VW dealer.
