Until November I used to live 5 minutes from the biggest if not the only (for all i know), biggest producer of adblue in this country.
I asked them the difference between the different iso specs and they said the numbers on the label. They said it just stipulates how it is stored and tested, the actual ad blue is the same stuff.
The stories of over filling adblue stopping your engine running are false, I know of a main dealer and multiple local garages including myself who fill adblue to the very top with zero issues ever encountered.
The adblue factory also told me to be aware there are whispers in the industry that more thorough adblue systems tests will very soon be implemented in to the mot test for light commercials and private vehicles with fines issued to any vehicle owner that have removed them. These tests are an expansion of those currently in force for hgv.

@Kombi140

Thanks, I’ll have a look

@Scoobysrt, good post from yourself regarding the adblue.
This is my first adblue vehicle so its nice to read up on facts regarding this.
I have read a lot of posts across various groups of people getting these emissions sensors deleted, but reluctant myself because, like you pointed out, mot centers are starting to clamp down.
The other year I was involved in fitting scr systems to generators that I had fitted for a water treatment works.
They went on island mode and this meant that of they ran for more than 50hrs a year they were required by law to have this system fitted.
I worked on the electrical side of this project and can see the corrosive nature of urea, it really is that bad.
The bulk storage tank inside control housing looked like sone one had sprayed white crusted rock salt across the components. Crazy considering system was on a few months old at the time.
Be interested to see how long the system lasts before it needs replacing.

Hi there i am having the same problems all said before , i would be so grateful if someone has the correct part number as when searching i find so many different ones. Can someone pls give me the part number they used

These are the codes im getting….
P229E00
P22A700
P20EE00
P229E00

Its very common issue and normal practice. You have 2 options: one is turn adblue off or try to fix it rapidly. I recomend first option.

Yes i agree they have made modern diesels a cash cow and they are ultimately designed to fail. Ad blue , dpf and egr are what let is down but more due to the adblue crystalising. The adblue injector over time gets crystalised rendering it useless as it gets blocked and throws up many diagnostic codes.

After a bit of reading and good old utube it seems these two products or similar are the way to go, might save someone a few quid in the long run:-

Forte exhaust crystal preventer
Wynns crystal clean and protect

The part number for a nox sensor is as follows :-
* 04L 907 807EB

* 04L 907 807AT. This is an older part number

Time to chime in guys,

My is a 2018 Maxi Life 2.0tdi 150ps.

It threw up only one code: P220B00 Sensor Suupply Voltage Bank 1 Sensor 2

I changed the sensor for a genuine VAG sensor.

A few weeks and 75 miles later it comes back on, once the engine is hot, in traffic for an hour. If I reset, the same thing happens.

Any thoughts?

Best regards.

What makes you think the sensor is at fault?
