2013 Passat TDI SEL:
Back in December, the check engine light came on and VCDS found fault codes:
P026A - Charge Air Cooler - efficiency below threshold
Intermittent - not confirmed - tested since memory clear
P20EE - SCR NOx Catalyst Bank 1 - efficiency too low
MIL ON - Intermittent - Confirmed - tested since memory clear
I took the car into the dealership. The MIL light was off when I dropped it off. They ran their tests and said the car was fine -- it didn't show a problem when they tested it. The MIL did not return.
Fast forward to yesterday morning on my drive to work. No MIL (per se) but a warning pops up on the display "200 miles until no start" and an amber warning flashes on and off every 5 seconds to warn about the ADblue system. There was no 1500 mile warning about needing to refill the Adblue tank.
By the time I get home, the warning is at "150 miles until no start."
Scanned the car with VCDS and found:
P20EE - SCR NOx Catalyst Bank 1 - efficiency too low
Intermittent - not confirmed - tested since memory clear
P208E - Reductant Injector Valve (Bank 1) - Stuck Closed
Intermittent - not confirmed - tested since memory clear
Additional tidbit of information include the reducing agent fill level is 77%,
so the DEF tank is not low.
I will drop the car off at the dealership for them to look at on Monday morning and see what VW says.
I believe I am very close to the 51,000 mile mark since my "emissions fix" so my fingers are crossed.
