Hello, i have a 2016 skoda octavia scout with a 2.0tdi 103kw 150ps engine CRMB is engine code, since last december when i brought from a dealership have now had 2 coolant pump C replaced due to bring up fault saying coolant pump 'c' stuck. has anyone had this issue with there engine and if so how you gone to fix this as i believe it not the pump it self as its a bosch part and when run actuator test it works you can hear it spinning, so what else can cause this fault to keep coming back maybe a sensor???

If there is resistance in the wiring then the current build up will give the ECU the impression that the pump is sticking or is stuck. Might be worth investigating the wiring next.

Exactly this. All that is needed is a corroded connection or very slight break in the wire for it to cause an issue. It might be worth getting that circuit checkes for resistance and if needs be, replace the faulty wire.
