...miles no matter what with a mixture of long and short journeys. Had a relative compression done and all peaks seem ok to me. Injector seals replaced, Sporadic P20EE only after a long journey. Garage said peaks look ok? I have had the van since new 150 CXHA DSG. 65k miles. Thanks for your...

Have you tried Wynns crystal clean and protect? You add a bottle in with the adblue when you refill the tank. I had the same intermittent P20EE and that sorted it, almost 2 years now without reoccurrence. Something to do with adblue crystallisation in the tank/injector system. It's only £8 a...

Hello all, I am in the same position with a T6 posting intermittent P20EE codes, I'm looking at trying to get my ECU software version checked and possibly get an upgrade if available. I called the local dealer who want to charge their diagnostic fee to look at the issue before doing any work, I...

Hi, I have exactly the same issue on a 2019 150bhp that was remapped by Pendle to 192. The emissions light has illuminated twice in my first week of owning the van, both times P20 EE which reset and cleared. The van hasn't been run in the last 6 months prior to sale to I think it may be ad...

...a couple of times, checked adblue injector for any crystallisation/clogging up & nothing A few more engine lights, the most common code being P20EE NOx, which seems to be a regular It had a software update in 2023 & fuel filter clean…seems to have helped I now only fill up with additive...

There’s quite a bit on Fault Code P20EE but, as @Sasquatch says, it’s well worth establishing if the issue is true and also reoccurring.

yes it was - was to clear a P20EE issue

hello all just had a software upgrade to clear an EML warning but now, the MPG i am getting is barely around 30 around town, and around 35 on the motorway. Was previously 40+ combined. its a 2018 T6, 150hp. anyone else had a similar issue?

...is still out of date - dealer requiring money to run diagnostics has put me off going to them Obeleven and adblue range indication seems to.indicate that adblues going through the system My fault was only intermittent p20ee no other codes So discounted egr straight away from faults thankfully

Worth trying shell v power diesel for what it costs worth a punt takes a couple of fills to.improve am managing long and short runs with no faults

Having pretty much the same issue with mine. Intermittent P20EE fault on longer runs. Had Nox sensor replaced but still the same. Not sure on my software version, I’ll have to check it.

...in, it came back two faults both of which they reckon would be sorted by the update: P204F (Pending) - Reductant System Performance Bank 1 P20EE (Pending) (Confirmed) - SCR NOx Catalyst Efficiency Below Threshold Bank 1 Anyway, it's done now and I can only take their word that things are...

Did you clear the fault memory between the runs? Just to get fresh start for each run - as this fault is based on NOx emission accumulation over time. Did you check fault memory after 90 mile run - to see if there the fault was already in pending state? Did you read the fault memory without...

...different road types So far 1 run of 90 miles flattish roads gave no faults 1 run of 145miles mixed speeds including hills gave intermittent p20ee fault and eml on More runs to be tried in the next 2 weeks runs all to be recorded Best scenario we get an active fault Worst case we gather data...

Yes your right p20ee my phone auto spelt it Only just got the van last week so unknown how long the codes have been an issue Looking through the service documents no obvious clues Just been out today 90 miles no eml but this just confirms its longer run issues No obvious regen cycle during...

I guess it's actually P20EE - which is not about the sensor being faulty. It's about too high NOx levels detected. Hmmm... any more info - has it ever worked without the fault? That would fix "false alarms" but if there is an underlying real fault can't cure that - of course...

Hi peeps Firstly what a great forum and excellent knowledge base I have spent more time on here than driving the van Thanks to the many posts on the forum my mind is at ease on the pe20ee nox sensor fault eml light co.ing on after buying obd 11 I can see this is an intermittent issue (happens...

Hi, is there any way I can find out about a software update for my T6 2018 150ps, it keeps throwing up P20EE and every now and then the adblue DEF faults and warnings, then they will go off and stay off for a while but come back up every now and then and reading on here looks like this may have...

I hope its ok If I steal thread As I got same problem with my t6 Purchase van 2 weeks ago and get error same day. As show on image was 4500ml of adblue Then 20 miles later was much less At this moment I'm unable to drive until next month and trying to sort it out and see what its a problem...
