Catalytic Converter Amber Warning Light, Adblue Issue
- Thread starter oceanromeo
- Start date
So the conclusion of the fault..............I made the schoolboy error of not reading the handbook and filling up the adblue tank to the brim when I got the van six weeks ago - they don't like this!
The tech was really helpful - diagnosed the fault via a call to tech support (it was showing an oil temperature sensor fault at first), syphoned out enough adblue so that the sensor could read it properly (it initially read 15 litres, and its only got a 13 litre tank), and then all was okay.
A lesson learnt, although nobody at work knew that you'd do anything but fill the tank until it was full, and we're in the industry.

So to update from my report of this warning light from 23 Nov. I hadn't had time to get the van booked into the dealers due to work commitments. 1000 miles of motorway driving later and the warning light comes on again. I call the dealers to arrange to get it looked at but they can't do so until 11th Jan - not much good when I'm planning to be in the Lakes in the van for New Year! So arranged for VW Assist to attend this evening. After hooking up his laptop, he advised to get the van more fully checked at dealers before using - in theory he said this will happen tomorrow now that VW Assist have 'referred' the van in - I await that theory to become reality! For those of you who understand these things, the breakdown report states this was done this evening:
"Carry out 6150 Test" and the result was "P00000" - apparently the software should normally report an error code with something more useful than just zero's?!!
"Carry out 6150 Test" and the result was "P00000" - apparently the software should normally report an error code with something more useful than just zero's?!!
Update: So, the van is now with VW Van Centre Wrexham. On giving them the paperwork following the visit from VW Assist last night, the service manager said that because the code is a "P triple zero", they will need to get in touch with VW UK HQ at Milton Keynes to be advised (if no resolution after that, advice would need to be sought from "the whizz kids" at the factory (VW Germany)). The van is driving fine, I strongly suspect the warning light is not indicative of anything serious as per previous posts in this thread..... to be continued 
Unfortunately I would say that's an impossible question to answer other than by yourself. The warning light has an originally intended purpose of alerting you to a problem that the handbook recommends you seek assistance for. My understanding is that the warning light can be triggered to be displayed for multiple reasons with some of the posts in this thread suggesting that the warning light is not always indicative of an 'actual' problem. However, how would you know if it is or isn't an actual problem without further diagnostic investigation? There is no right or wrong answer, some are happy to continue driving with the light on, others not. For me, with a 3 month old van, I'm not prepared to take the risk of voiding the terms of the warranty by ignoring the warning light.
Sorry to hear you've has this experience so soon into your Kombi ownership, hopefully it turns out to be nothing and the rest of your ownership experience will be plain sailing
Thank you replying
VW assist out this morning and diagnostics show “possible build up /dirty” filter as others have suggested in the forum. But your right and the man also said your don’t know until diagnostics are run.
So my van goes into dealership over Xmas
Looking forward to a stress free van afterwards
I understand this may happen again if short distances are consistent with its usage, which may have been part of its former life and apparently checking that filter is not part of the dealership check if no lights are on board dash
Merry Christmas all

Hello, have been looking at your conversations about the Catalytic Converter Fault warning light. We have recently experienced this problem coming back from Wales in our T6 (T28). It was not flashing, so the manual says take it easy and driver to your local dealership.
Did that 2 weeks ago, and was horrified to pay £108 for the following, shown on invoice..
"Investigate Catalytic Converter warning light on.
Carried out GFF finding P20E00 adblue event stored.
Refer to TPI 2054601/5 as known issue.
Carried out Engine ECU Software update as TPI.
Cleared Events and test ok"
Having been a Systems Engineer and married to a Software Engineer, I demanded a full explanation of the problem, how can you have a SW update fix a known problem and charge me? A heated conversation followed. I asked why I had to pay for a SW update , Madame your Van is out of warranty! I asked when the update was available, I was told 03/03/20, my van was in warranty then, you could have updated at the last Service in Feb 21 at least! I was told that a corruption in the ECU had occurred and that this update would cure it, but they could only update it if the fault occurred, also said that VW did not pay for "Enhancements", this was normal, what enhancement I thought!
I said I would complain to VW, and I rang their Customer Service, initially they said I should not have paid for the "repair/update" and said they would get in contact with the dealership and get back to us. We waited.
Meanwhile we went off to Wales again for the weekend; low and behold 50 miles up the road on comes the bloody light again with no obvious change in driving performance. So we camped for 3 days and then came back and rang VW Customer service as they had not got back to us.
This time they said they had contacted the dealership and we did have to pay because it wasn't a software update, it was a fault. Apparently the dealership should not have given us this technical information, why not? My husband then had a good discussion with her about the "repair" again and asked why it takes 4.5 hours to update some SW. He then mentioned that the problem may have reappeared and were VW happy that their technical effort as it may have not solved the problem after all! Upshot VW is getting in contact with the Dealership to ring us, explain what they did the first time and to book it back in to "repair" it again. I will keep you updated.
Sorry about the essay but is this info useful to anybody? Or could anybody shed any further light (sorry the pun!) on the fault, sorry SW update!

Thank you - yes, I'm very much interested. Actually my favourite topic around the Forum.
