- adblue fault codes
Topped up adblue a little over 3 weeks ago, range was 5500 since then, driving today and the error comes up as blue low, engine won't start 650miles range.
This happened a couple weeks ago and after a few more miles of driving error disappeared and range shot back up to 5500.
What is this issue?

Software update.
I assume this is your van?
Blocked EGR cooler.
Coolant pump fault
Injector 3 (that includes the pressure sensor)
I would clear these and see what come back.
You really need to see the details of the faults to see which one is bringing on the MiL light.
Never fill it right to the top you must fill only by the amount shown on the display otherwise the ultrasonic sensor can't determine how full it is and that can cause the error.
I had my van checked a couple of weeks ago to see if it need the software update and was told it was not needed. It’s a late 2017 Kombi Edition. Sheffield told me the update was only required on a small number of vans! The more and more I have to deal with main dealers the less faith I have in them.
I've asked both Liverpool and Stoke to check this and it seems beyond them......
Hi guys,
I have this recurrent issue. The van drives perfectly but I have got the engine management light coming up on my dash after few hundred kilometers (distance varies, light usually came up on motorway) it is always the same error - the top one, and sometimes others. They tried updating software, and now they cleaned the system and changed the glow plug1 I believe. The error has returned. This time it disappeared for some time and then returned after downing the fuel almost to empty (motorway mile s only, the EML light came up after starting the engine few days later but before refueling). It is unfortunately out of manufacturers warranty now.
My van is a VW T6 150 bhp DSG euro 6 T30 from 2017, original manufacturer's map, stock wheels, always refuelling to full and I don't overfill the Adblue.
I know I am not the only one with such problems. I wonder if we have people here who sorted the problem out definitely.
I would like to avoid mapping out the EGR, Adblue and DPF

Make sure your EGR flexi pipes (front and rear) aren’t leaking. This is detected as a low flow, which means the EGR doesn’t reduce the NOx as much, and the AdBlue has to work harder. It gives up at a point and flags an error.
How can I detect the leakage?
EGR flexi-pipe: Exhaust Fumes In Cab, Hissing From Engine Bay.
have realised it is the egg pipe too A good Freudian slip there :)

As above, but mine was showing spot staining too!EGR flexi-pipe: Exhaust Fumes In Cab, Hissing From Engine Bay.
