...seen my other post re the validity and value of the All-in-Warranty from crank case oil seal leak to failed engine mount and finally ongoing P20EE and P204F faults causing engine emission light to activate (strangely only during a long run). There is another thread currently asking is the...
...itself with a different code. AFAIK there is not a single failed sensor reported on the Forum, just a couple of replaced ones- not curing the P20EE issue.
65535 (hex FFFF) is more just a "sensor not ready" indication. It will come to life when warmed up - takes some 10-20 minutes to reach...
...given the leak was immediately evident however do I share his confidence I am not sure. will be doing a run next week so watch this space for an update.
Interesting that for all those suffering this issue that this could be an item to look at ...... the problem is the P20EE code is so generic
@n10n here is the detailed ECU info: (I copied it and forgot to take a screenshot of how it was split up on the screen. Hope it is readable!)
ECU info obtained with Carista 8.2.2 for iOS: VIN: WV1ZZZ7HZKH041064 CAN network gateway Part #: 7E0909901 Component: GW-K-CAN TP20 Software version...

As for the glow plug fault 15916 I believe the malfunction frequency counter will go up if the fault is reoccurring...
...then reset back to 5500 but then popped to 640 again, drove it all the way down to 30 and wouldn't reset.
it's got 4 codes that keep coming back:
31103
33262
P20EE
P204F
When I get it back will let you know what they've done to sort it... hopefully sooner rather than later and for good this...
I'm gettin the van looked at later this week but thought I'd take another poke around the sensors earlier on.
It seems as soon as the engine hits 90/91 degrees it runs normal, or as good as!
This seems to coincide with the Nox sensor kicking in from 65535 ppm down to 4 ppm. (Presumably working...
P20EE (Generic OBD code) = 31103 (VW specific code).
Pending DTCs are fault codes that have been identified by the ECU but are deemed not yet critical enough to trigger the MIL.
got the same issues despite the van now having been back to VW twice for P20EE code bringing on emission light
first visit - light on
had glow plug 3 replaced
software update
EGR test, no flush
adblue system tested no repairs
second visit - light on different fault
after first visit drove 10...

...different (P2200=NOx Sensor 1 - Electrical Malfunction). The definition “nox catalyst below threshold bank 1” is more related to e.g. code P20EE.
What sensor exactly, front or rear NOx? - AFAIK NOx sensors do not report temperatures, however when they are initialized their self-diagnostics...
Update on this:
The fault codes that the workshop got were P204F and P20EE. When I contacted the workshop they told me they'd need to replace the NOx sensor, reserved a time for it and told it would take two hours. I brought the car and waited nearby. They changed the sensor quickly but the...
I’ve got an Engine warning light on the dash, on inspection it’s given me PO671 - bank one glow plugs, but it’s also flagging up P204F and P20EE, these relate to the reductant system performance and catalyst efficiency of bank one.
Is it possible that the faulty glow plug is causing the...
I Have this (cheap) OBD11
The engine light is on and the code is P20EE which I assume is NOX sensor fault.
I have had this at least once a year and it has reset after driving around for a few trips.
This happened on a long drive in France but disappeared again after a couple of days.
Then it...

Van Mapped when out of warranty with 40k on the clock
First time van remapped, p20EE started showing up after about 2 years driving.
Read on OBDII and decided to clear it.
Did about 650 miles light back on, again, cleared it and...
