Engine light, Ad Blue Light+Spanner & Ad Blue range..aarrgghh!!

[DavidS]

Hi Guru's,
Need some thoughts, help, advice.

Took possession of Vincent (Asbo Orange, 150bhp, DSG), and Ad Blue range was 5000miles. The engine light came on (no loss of power), parked up until next day. Jumped in stated up ..Ad Blue dropped to 650 miles and the Ad Blue +Spanner light came on.

Called supplier who said take to garage and get it checked. Called rescue service who advised if no loss of power, vehicle probably need a good run. Advised supplier the same, they agreed. Took Vincent for a run or 2. No change to lights, eventually Ad Blue range down to 600. Call supplier who suggested top up the Ad Blue with 10 ltrs..... I added 3.5ltrs. No change, another run Ad Blue @500.

Took Vincent to local garage who did diagnosis check and got a few codes that they reckon were all related to Ad Blue and they didn't want to "interfere" with and suggested I should take to specialist. Called supplier, no problem get it booked in. Booked Vincent into specialist at earliest available slot.

Into Vincent this morning to get something, put key in ignition, no engine light, no Ad Blue light, no Spanner & Ad blue @ 6000 miles. Short run, same. Ignition off grab a cuppa, ignition on, no lights, Ad Blue @6000 miles. Specialist appointment in a couple of days.

Is this likely to be "rectified", a gremlin or something that is going to recur regularly? Specialist is 22 miles away and if theres no fault showing costs of getting a diagnosis done will be mine plus we will need to get time off work to get there to drop off, then go back and pick up.

What folks thought on this?

Need a software upgrade from the main dealer.

Another adblue issue.

I've read the other posts on this subject but am still at a bit of a loss so please bear with me. I drove 400 miles yesterday in our van and checked them adblue level before I left. It read 3000 miles of range remaining. 300 miles into my trip, the beeper sounds and dash lights up with the...

Cheers for that - off to the specialist it goes then.

Revo will do a software update when you get a remap........ just saying for reference


(Note: the remap is not actually required, just a light hearted comment as you get also get a VW software update at the start of the process)

 

[DavidS]

@david173 - Revo is that a franchised remapper?

@david173 - Revo is that a franchised remapper?

Revo is a remapping company and thier software is available from Revo dealers across the UK. loads more info this forum on Revo if you run a search.

 

[DXX]

He wasn’t asking for a remap?
As @Loz stated the van needs a main dealer software update.

I know.
It was a joke, as you get the main dealer software update when you get the map 2 birds one stone and all that.

But your right, I should have made it clearer that the map is not actually required.

Ill correct that above

Guys what's the low down on the ad blue, I have ever used it before are there different brands like car oils, or its a one product fits all. Is there any thing else I need to do except send it into the funnel? Any engine technique or any advices that I need to know. How much does a t6 need if the warning light has come on?

Try a search first, there is loads of info.

Some major points, don't get it down to below 600 miles. The van won't move.

Don't splash it on your paintwork.

Fill up what it says on the dash display. It reads gallons, so convert to litres.
I used a pump at a fuel station today, much easier. After filling, turn ignition on but don't start until the range changes.

HI
I have exactly the same symptoms like Davids, the 650miles appear and disappear , then engine light come on with three alarms or one alarm after reset.
We drove with this changing status via Germany, Netherland, England up to Scotland. I read above that software update is suggested. On my is 6166 , is this is latest version.
I need to admit that there was work done on dpf due to fact that I spotted that dpf was recycle every 120miles, but no alarm or 650 miles magic message to this point. Filter was cleaned by professional company and removed by mechanic. After cleaning process there is 650 miles message and after magic reset engine management light appear, no lump mode.
I connect the vcds today after return to home. Attached few files with faults in different part of investigation.
Please help!!!

After cleaning process there is 650 miles message and after magic reset engine management light appear, no lump mode.

So no 650 miles message between January (here) and the cleaning?

On my is 6166 , is this is latest version.

Yes, the software is up to date.

Could you please make blockmap files from 01-Engine and 17-Instruments
How-to - as below

EML Light on, VCDS scan implies an SCR fault?

Happy New Year to All! I managed to sent sensor across channel and unit is replaced. Now, after ECU scan alarm Nox sensor disappear, unfortunately message on the dash board still display 250miles :( . I try to utilise VDCS version 22.10 to reset , but I can't find this function(there films on...

Hi MMI
First of all apologise for long time to response , I was away for few days from home. I made a few logs of 01 and 17 , from begining:
- 1932 - 01 -engine stopped after running approx 20 minutes
- 1934 - 17 -engine stopped after running approx 20 minutes
- 1935 - 01 -engine running cruise control 2000rpm
- 1938 - 17 -engine running cruise control 2000rpm
- 2044 - 01 -engine stopped
- 2046 - 17 -engine stopped
- 2046 - 01 -engine running idle
- 2048 - 17 -engine running idle
Symptoms are similar but 'touch wood' 650 message not appear again, DPF re-generate every approx 200- 250km , is this is normal?

Had this issue before, got stranded in France as the beast from the east hit in Feb 2018 when Europe assistance said van could not be driven and we had to be recovered to a vw garage. Long story short no joy with my dealer who when the fault reoccurred back home. They said that the vw instruction for the fault code stated “ reset take no further action “ so would not get paid for work to investigate fault. A helpful vw service manager in Holland told us the fault is caused by the exhaust not running hot enough to keep soot from affecting a sensor. On long motorway trips our 204 ps dsg is sitting at 1500 ish rpm. He said that on long low rpm drives every 300 miles or so put it in manual and go down a gear or two to get the rpm above 2000 rpm and drive about 3 miles or so. This heats up the exhaust and clears the sensor. We have done it ever since and the problem has not happened again. I use my trip on the speedo to remind me.
Gave up asking about software updates dealer fixes, etc. Have more info but heading south to get the ferry off wandering again cheers.

Thanks - very interesting...

Did you get emission light on dash - see the "active" below in log (after/during each mentioned run)? And cleared the faults in-between? What was the fault code?



Interestingly there is still some discrepancy of remaining AdBlue range between 01-Engine (below 7400 km) and 17-Instruments (above 5000 km).

Below in yellow NOx related values - which are different what I hav observed on mine. Mine registers only "marginally increased NOx" - all the other are plain zeros. I don't know what they mean exactly but they seem to be coincide with AdBlue discrepancy (between engine and dash).

The others are what to expect - e.g. indicated AdBlue pump pressure.

Hi MMI
Thank you for prompt response.
Answer to your question about malfunction, yes the lights(highlighted by you) were indicated because engine was stopped.
I would like to put more facts:
- dpf was re-generated approx every 120miles
- decision was taken to clean the filter
- cleaned dpf by specialist
- after dpf cleaned process engine management light appear with below alarm:
32110 - Diesel Particulate Filter (Bank 1)
P226D 00 [100] - Damaged or Subrate Missing
- saga started with magic 650miles after message disappear there was three faults:
1/
32110 - Diesel Particulate Filter (Bank 1)
P226D 00 [100] - Damaged or Subrate Missing
2/
33262 - Reductant System Performance Bank 1
P204F 00 [096] - Malfunction
3/
31103 - SCR NOx Catalyst Bank 1
P20EE 00 [236] - Efficiency too Low
- Alarms were cleared before MOT
- Yesterday after all tests, there is no alarm on the engine block
Questions:
-Is this is normal that dpf is re-generate every 220-250km
-Any settings to be adapted /changed after dpf clean process to include removing unit from the the van, sensors etc.
Thank you

 

[mmi]

Thanks for the clarifications.

I would like to put more facts:
- dpf was re-generated approx every 120miles

Well, the expected lifespan of the DPF is maximum 300 tkm - so a kind of expected.

- after dpf cleaned process engine management light appear with below alarm:
32110 - Diesel Particulate Filter (Bank 1)
P226D 00 [100] - Damaged or Subrate Missing

Do you still get this fault? Is the exhaust tailpipe sooty?

33262 - Reductant System Performance Bank 1
P204F 00 [096] - Malfunction

31103 - SCR NOx Catalyst Bank 1
P20EE 00 [236] - Efficiency too Low

In the earlier logs there were as "intermittent" - do they still come back?

-Is this is normal that dpf is re-generate every 220-250km

Sounds normal to me. The DPF regen distribution below is what I have got. Anyways, the regen interval depends on driving style and especially how long journeys are. The longer the better.

-Any settings to be adapted /changed after dpf clean process to include removing unit from the the van, sensors etc.

In engine adaptations:

IDE07903-Adaptation of ash mass​

But it has been already done quite recently - some 3000-4000 km ago


Maximum 110 grams.

Hi MMI
Thank you, information are really helpful specially the dpf regen graph.
Last time I reset alarms before MOT, currently( last two weeks) I don't use the van very often, then I can't say if the alarm come back. I will use my van this weekend ( camping )
I will let you know if any alarms appear.

I would like to put more facts:
- dpf was re-generated approx every 120miles

Well, the expected lifespan of the DPF is maximum 300 tkm - so a kind of expected.

Can you please clarify is the was worth to clean the dpf or better to look at for new unit?
Thank you again

Wish I had the definite answer. As for specifically for T6 my concern is the SCR/NOx catalytic converter at the end of the DPF. The catalytic converter takes care of the actual NOx reduction. I'm afraid that cleaning possibly ruins the NOx/SCR catalytic converter. So in the long run the safe option of course would be to replace with a new unit - it would give another 300 tkm of running time.
