Hi,
Long time VCDS user, but 1st post!
I'm having trouble after the Sharan presented a "600mile" adblue warning out of the blue - and after a refil is not resetting.. Heres some info on the vehicle and the timeline of events.
2012 Sharan 7N, 2.0TDI DSG (CFFB engine)
Owned since: July 2013 (11k miles)
Status of car: Stock.
Dieselgate: Dealer "fix" applied when VW contacted us around 2016. A few weeks later, a fault developed with the NOx sensor, which was replaced (under good-will).
Dec 2024: VW Dealership carried out an Adblue heater replacement due to fault codes (sensor level).
No issues when topping up the Adblue fluid before or since Dec 2024.
Various other issues not related to emissions: Ignition barrel 2021, Aux heater pump replacement 2024, Air con compressor March 2026, DAB reception dead (ongoing).
End of March 26, the Sharan took the family+luggage on a faultless 600mile round trip. Predominantly motorway speeds of 60-70mph.
Visited friends who previously had a Seat Alhambra, but sold it due to numerous electrical faults and Adblue issues...
I made the mistake of saying out loud "Ours has generally been ok other than general maintenance, semi regular adblue top up and the adblue repair in 2024"
08th April, during a 40 mile motorway trip - Adblue light and warning reads "Fill Adblue, 600 miles until no-start". At one point I had an abnormal warning saying "start stop disabled" (or something like that - I was driving so didnt catch the complete message)
Later that day, 10 litres of Adblue added in one go. However, I made the mistake of not waiting a minute before starting the engine.
Adblue Light remained on and warning still shows on start-up.
Fault codes scanned (saved log) and cleared - SCR tank level detection reset & reset SCR lock.
Adblue Light remained on and warning still shows on start-up.
09th April, I was curious whether the tank needed more (but having performed a reset, felt VCDS would not give a true reading) - so added more fluid... a further 5-6 litres - she must have been very empty!
I repeated my mistake of not waiting a minute before starting the engine. (facepalm)
Adblue Light remained on and warning still shows on start-up.
Fault codes scanned (saved log) and cleared - SCR tank level detection reset & reset SCR lock.
Adblue Light remained on and warning still shows on start-up.
Attempted SCR Efficiency Test (with pre-reqs met. Engine temp 80+, doors/hood shut, park, handbrake, drivers seat belt in) - failed, unsafe. Told to turn the engine off then on again
Took it for a 30-40 minute drive: 50-70mph.
Adblue Light remained on and warning still shows on start-up.
Attempted SCR Efficiency Test (with pre-reqs met. Engine temp 80+, doors/hood shut, park, handbrake, drivers seat belt in) - failed, unsafe. Told to turn the engine off then on again
most recent log file attached.
I suspect the:
"15733 - SCR NOx Catalyst Bank 1 - P20EE 00 [00100111] - Efficiency too Low"
Is my blocker to running the SCR Efficiency Test. However I wanted to double check with those far more knowledgable than me before spending £300+ on a new NOx sensor :-)
