VW Kombi 2013 TDI 1.9 Coolant Pump B Open Circuit Fault - How to Diagnose and Fix
I'm experiencing a coolant pump B open circuit fault on my 2013 VW Kombi TDI 1.9 diesel model. The check engine light is on, and the fault code indicates an open circuit in the coolant pump B system. I've checked the wiring and connections but am unsure if this points to a faulty pump or a sensor issue. Can anyone confirm the typical causes of this error on this specific vehicle? Any guidance on how to properly diagnose or repair it would be greatly appreciated.
