P20EE fault code rectification

[scrimshank]

Waiting to get remap still have intermittent light but stuck with vw wanting to charge 130 to check the system but I know the software is out of date and that's all I need as the software controls the amount of adblue used and amount of cleaning of exhaust s3nsors are good adblue being used but slowly and ecu checks says low adblue injection additives didn't do much in regards to adblue delivery exhaust is clean no diesel blackening is as random as it always as been I k ow that every 3 or 4 runs or on a long run the orange light will come on to keep me company trying to resist just reprogramming the ecu to ignore adblue even though its tempting
Running hard just uses more fuel the light will still come on - mines a van look alike so stuck with 50mph but most of time in the dales lucky if I can go that fast with sightseers about most days I'm out
At least it Can be reset easy enough
Oil steady no rough running had the local garage look at it a few times nothing obvious going wrong

Thanks @Bandit1201.

Have you had your adblue injectors cleaned/replaced?

I am tempted to take the van to the nearest VW dealer but worried they may decline to do anything as the van has been remapped.

Based on some advice I've had I'm tempted to get the remap deleted also. A SW upgrade/refresh would handily do both of these things so may try and find an independent willing to do this.

I'm pretty sure the vw will refuse hence I don't trust em with the £130 to look for fault reason
I'm looking for someone reliable for remap but it's not that easy local garage popped injectors and had a peek said looks OK
Local garage said he could just replace everything but doesn't think it will cure it he's convinced its in programming

Haven't thoroughly read all this thread, but
Had my 150 was pendleton mapped from new,
Eml on on the journey home (300 miles)
5 times more over following 9- 12 months.
Software update fixed it.
Revo remap after a couple of thousand light free miles , 70000 miles now without a light.
No sensors etc needed.
Definitely try a software update if not yet done

Thanks @teamfly, how did you get your software update? My local dealer will not apply it on request they want to charge me for diagnostics before doing any work...

Cheers

I was waiting for the software update to come , was part way to rejecting the van.
Think was one of the first to get it.
Never really sure what part the pendleton map played. The update wipes the remap.
The first 10 000 miles were a nightmare with the van , no issue since the update.
Even if you have to pay for it , I'd say worth it.
Good luck

Thanks again, did the dealer do the update for you as a recall or did you have to book it in for a diagnostic?

 

[teamfly]

Recall , as soon as it was available.
I was about to reject / return the van though.
Can you not find a dealer willing to update to the most up to date software given recurring light ?
I think the diagnostic fre is a pretty standard thing ?

 

[teamfly]

Failing that try the pendle map off it.
Was never sure but it may have been an issue

Cheers, I'll give the local dealers a call tomorrow. Thanks again.

Software version 3771 on mine is one of the updates required to latest
If you do goto dealer let me know how you get on as I have to sit on a awaiting list for an appointment at my dealer last time I rang

No worries @Bandit1201, will do. Did the V-Power usage reduce the frequency of the Emissions light?

No stayed the same did miss a regen at switch off once where the van fan runs on but thats just coincidence i think no change otherwise pretty convinced its the software version

I dropped the van into the dealer last week, apparently it has the latest ECU software version already installed and so they returned it without charging for anything.
Since the visit I've done a run down to Cornwall and back and had no repeat of the warning light, I have also put some Ad Blue cleaner in and a diesel additive into the last top up prior to the long run down South.

 

[Bandit1201]

That sounds hopeful i wouldn't get to Cornwall without the light coming on

Hi all,

Been trying to fathom why my van has been doing more frequent regens over the past year. It’s had the latest software to note. CXHA 2019 model. Had a sporadic P20EE on longer journeys but not returned lately. But in the readiness monitors it says scr incomplete always. I’ve logged egr values, logged ad blue and Nox levels together monitored DPF etc…. Attached a log photo of the graph.

The Nox spikes over 1000ppm under load which is way too high. I’ve checked the ad blue injector dosing test in vcds whilst removed and all looked ok.

I’m assuming it’s a misreporting Nox Sensor drifting. But it’s an expensive assumption!

Any advice before I pay the Vw ransom?

Time for an update on the issue
Sorry to anyone waiting for updates for the delay I wasn't sure where I was with the fault so I set a 3000 mile goal when it cleared so here I am with update
I have now run for 3 and half months with zero faults fingers
Still running pendle remap and on same software version since my last post i have done nothing but religiously use v power shell fuel
Was running 25mpg nowadays im getting low 30s some long runs up the m6 to Scottish borders letting the van run hard for good periods 70 plus uphill getting some temps over 102 on the oil display off the dash display local roads tended to be lower oil temps seemed to clear the fault since it cleared I have run 50mph or less a lot but still have some spirited runs on the motorway occasionally
I gave up with cruise control seems car drivers are slower than the average vw driver so cruising a nightmare through the dales
The fault light was on off for a good 2000 miles but since I have done 3000 miles with zero fault except the usual door not locked or shut because someone opened it whilst scanning
Hand on heart i can't say it's down to v power fuel but I can't say it wasn't the cure will let you know if it goes down hill and the dreaded light returns

 

[Bandit1201]

Forgot to mention a minor change
I changed the settings to allow the van free wheel down hill forgot what it's called on the display that boosted mpg for sure
Still have stop start activated
Ditching cruise as definitely benefitted the van on longer runs of 50 mph it definitely prefers a variable foot at the pedal highest mpg in last 3 and half months was 38 mpg average whilst trying to challenge the fault light with driving like miss daisy for a couple of weeks

Thanks for the update, what is the freewheel setting you adjusted?

Thanks,

Chris

Hi Chris had a senior moment the other day with freewheeling = "coasting" or eco mode on the dash board settings basically the van runs down hill like it's in neutral rather than holding high revs or revving high p.s mines dsg auto
