No, as I said I have 2 perfectly working pumps, so I'm pretty confident that the problem is in PCB and as it is somewhat intermittent, I believe it is weak soldering. I haven't taken the PCB out yet, because I'm not sure if the problem is actually in the water pump circuit or somewhere else and it just throws pump fault.
That's why I hope to get some diagram for it, a user in here got one, so hoping someone in here knows where to get it. I tried to search Hella diagrams every way I could, but no luck.
