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.

Yes, the light came on with about 90 miles left
Sorry dude... this confuses me? 90 miles left?

I thought the 1st warning was white Fill AdBlue (1500miles) warning
then 2nd warning was yellow AdBlue fill (1000miles)
then last warning was red Fill AdBlue (no start capable)

You're saying you never even got the white and yellow warnings?

Okay, still confused. Is the Adblue tank full?

Could it be that you just need to fill it up because it's empty?

I am not clear what happened here either but are you aware that after you fill the adblue tank you turn the ignition on engine not running for 30 seconds to reset the sensor?
