Readiness: 0 0 0 0 1

I wonder if your ECU SW is up to date?

I was focused on that lack of readiness (Readiness: 0 0 0 0 1 ) because a fault code may not be stored yet.. but after checking his SWL I found a bunch of dealer level TSBs and flash updates. I would have this car updated to the latest version at the VW Dealer to rule out buggy software at some point.

Did you have any AdBlue or exhaust emissions fault codes? Perhaps P2201 - NOx Sensor Circuit Range/Performance Bank 1 Sensor 1?

Edit, I had that draft open for an hour or two before I got to save so I'll need to see if that fault you just mentioned is related to the P2201 TSB. Please post another scan with faults if they return.

I have a CKRA on bench now and yeah firmware is 4804.........

Gonna recode on bench in a few after I make my backups.

Dam password Tricore 1797 what a PITA EDC17C54...... like watching paint dry :banghead:

Ok recoding does do a default of those values!

9645, was the pressure to low, put in a new adblue sensor, and cleared it. no codes came back, just not sure if should leave the car running or not or if im limited on how many startups etc. ?

How cold was it when the sensor failed? Do you live in a cold climate?

I bet the injector is crudded up for the addpiss..........

Nox sensor is also most likely contaminated.

Clean and burn the NOX with propane torch if it is.

Did you do the default recode?

Please post logs and auto-scan if you can.

Hello all,

I have a similar issue with a 2012 Passat TDI. We recently purchased it second hand and have had the Low AdBlue warning light come on twice. I checked the level, even topped it up and still having issues. The first time I had the issue, the warning went away after having the key in the ignition for 40 seconds or so without starting the car. The second time however, I've tried the key, I've tried resetting the SCR reductant tank level both without success. An auto-scan revealed the following:

Any thoughts on how to resolve this would be truly appreciated. We were hoping to do a cross Canada trip up to the Yukon soon...but the way things are going...we may have to delay.

Cheers,

Stephane

Hmm... We'll have to do some digging to see what we can find out.

You think that OBD2 mode would read this and perhaps supply generic OBD2 code definition? Never tried on diesel but did on many gas engines.

It couldn't hurt to try, but it bugs the heck out of me. That shouldn't happen on a 2012 car.

Dec into Hex shows P3D75, no data.

I am not surprised. When in native VAG mode, Bosch UDS ECUs do not usually produce "standardized" SAE/ISO fault codes. The codes they produce use an arbitrary numbering scheme that must be translated via a look-up first. The question is whether we missed 15733 somehow. We've seen at least one instance where a fault code was defined in early versions of "source" data and then was dropped in later versions despite being a commonly-occurring code. Sometimes VW and/or Bosch do things that make no sense at all. Of course there are other explanations possible as well, but I want to eliminate the possibility that we missed it before I start speculating on them. ;)

You think that OBD2 mode would read this and perhaps supply generic OBD2 code definition? Never tried on diesel but did on many gas engines.

BR, Andy

Sorry gentlemen, made the rookie mistake of clearing that fault before fixing the problem. Went for a little drive last night, AdBlue warning still there and counting down. I thought that perhaps the fault would come back but it didn't. All this to say that the AdBlue warning is still persisting. :banghead:

OK, reasonably confident that the "unknown" fault code should read:

15733 - SCR NOx Catalyst Bank 1
P20EE 00 [096] - Efficiency too Low

It's in some of the other data for almost identical engines, but not in this one.

Yeah and the new diagnostic platform incorporates JCE. So, looks like no go 4 now.

Thanks Uwe!

Looks like I need to find out where that NOx sensor is to pull it and burn it as Jack suggested. Is it the one in the NOx cat? Or do I need to look somewhere else.

Thanks again!

Just thought I'd post an update to let everyone know the cleaning did the trick. Had to drive an aweful long time to get the warning message to go away though. Had me sweating...am really loving german engineering right now *sarc*

Thanks all for the help.

I guess that can be added to the list ...............:rolleyes:

Glad it helped!

Did you blow holes out with bit or make larger or just do a burn off?

I have found two reasons this happens.

1 : Oil Is contaminated with blow by gases and fuel + being sucked into the combustion process.( ring seal )

2 : USA fuel is of poor quality for centane value and doesn't meet the spec the systems were designed to operate in.
