On my 2012 Passat B7 140HP, 2.0 CR the EGR cooler had a water leak in the gas re circulation system. It was replaced but I'm not sure if this is a construction problem or it was generated by another part. The auxiliary electrical water pump has an irregular sound, I want to change it but I'm not sure if it can be the cause of the EGR damage. In it's case I suspect only mechanical problem because there aren't any errors neither on the cluster instrument nor on VAG-COM.
I am also concerned about the DPF because of the water which was exhausted for 10-20 km till I arrived in the service.
Can this be a problem for other parts of the engine?
