Another up date on the ongoing saga with the ad blue fault.nissan dealer now going to give me a loan car until my car is repaired.they still havent fixed the problem by following nissan flow chart guidance. They have now sent all data over to nissan technical support to assist with fault finding.looks like it is the adblue control unit but they not allowed to change it without nissans approval. Service manager did say it could take upto a couple of weeks to get sorted.

Just an update, Got my car back today.Garage have fitted a complete new adblue tank which includes the control unit under warranty following advice from nissan technical.
Nissan technical going to be in touch with me over the next couple of weeks to check on progress.
They must be of some interest to them.
I have asked for a technical data report for fault. Will update post if i receive it.

Greetings one and all, first time poster.

Just reading this thread and my Qashqai is having the same issues. It has already been into the main dealer once for an Adblue fault (orange fault that counts down) and they did a software update, and topped the level up. This one is the white lettered fault ,the one that says 530-500 miles range and the Adblue light isn`t on, but the EML light is. I`m quite savvy with diagnostics and other electrical stuff, tested the battery without it running and it reads 11.83v. Fault code reader brings up p20ff, which is a Nissan specific code and isn`t in my readers directory. Ironically this has happened both times after I`ve topped the Adblue up, maybe about a day after, very strange. It was 3500 miles last time before it needed topping up.

Many Thanks

I have the same engine and the only AdBlue fault I have had was battery related.
