Just joined the Z4 club this week with a 2008 3.0si coupe! Super excited about it and loving every second! The only issue as of now is the windshield washers aren’t working (the nozzles that squirt out fluid).
Local BMW mechanic cleared a couple codes for me, but was still showing this fault code relating to the nozzles;
GENERAL MODULE 5
(GM5) (zke5_s12)
74 Spray nozzle heater, left: open circuit
When I try to spray them, I don’t hear the pump trying to do anything so I feel like the pump maybe needs replaced, but that fault code seems to indicate another issue. Any thoughts?

Windshield washers not working
Heated washer nozzle on the left has burnt out going by that code, shouldn't have affected the pump, if you cant hear the motor running first check the fuse is good. If the fuse is ok then need to check if the motor is getting 12v when the stalk is operated, if 12v is getting there then pump may have died or its blocked with gunge. Best take the reservoir out and give it a good clean out also blow the water lines to the nozzels out with some air if you have a compressor.

The bottom of the washer tank gunges up over time and clogs the pump. (A result of Cheap screen wash) You could try running boiling water through it. Others on the forum have suggested Milton steri tabs dissolved in the tank. Failing that take the tank off, remove the pump and clear the jelly like gunge that will have settled in there.

Windshield washers not working
Welcome to the forum by the way.
When the screenwashers on my previous E86 wouldn't work I took the reservoir out (not a difficult job on these) and found the filters on the washer pumps smothered in green gunge! Cleaned them up, flushed the reservoir, put it all back together and filled it - working washers.
BMW screenwash seems to do this whenever you put any other fluid in with it. I just used cheap stuff from a supermarket and had no issues over the next 3 years - the secret seems to be not mixing brands.

Thanks for the suggestions! I replaced the pump today and now everything is working! Seems a little odd considering the code I got referring to a specific nozzle, but everything seems to be working as it should now!
Thanks!
Thanks!
