I have a 2015 TDI Passat, last Friday the adblue light came on suddenly and by the time I got back home the adblue warning light had turned red and the car will not start. There is a device towards the back left of the engine that receives the adblue from the tank and the pump is working fine. Can someone identify the part, what it does? My check engine light came on also and I'm baffled as to why it would fail.
