2015 Passat TDI SE, 123,000
Friday the DEF notification came on 600 miles before no start. I just recently had the oil changed so logically I figured the dealership forgot to top off the DEF fluid. Stopped in Saturday to have it topped. Notification never came on Sunday.
Now yesterday Monday, it's back 500 in range and now accompanied by a CEL. I did a bit of research in the forums and came across a few items, possible NOX sensor, possible DEF heater etc....
Does anyone have a few suggestions in diagnosing and repairing this annoyance without having it expire, towed to the dealer and pay a big chunk of change.
Thanks in Advance for your assistance.
