Adblue tank repair details

[dsgoody]

Yes, I actually had the P20F6 fault around 250km (apologies, car is currently set in km due to being in France) before the P20E8 fault. I've cleared both, and only P20F6 has returned for now.

The description for P20F6 was something generic along the lines of 'Engine Fault, Repair Needed' along with the engine management light being illuminated. Apologies, I can't remember the exact wording.

What I really need to do is get it connected to Diagbox and have a look at the output of the pressure sensor to see if it's reading anything at all, and manually check the operation of the pump. Of course, I can't do either of these until I get home.

No, I meant the description from your code reader. That's what displays on the screen in the car.

Apologies.

P20F6 - DeNox system circuit - Leak detection
P20E8 - Pressure of the urea fluid - Urea fluid pressure too low

I topped the tank up only 1000 miles ago, so I'm not low on fluid.

I've ordered the cheapest second hand tank I could find as a quick fix for now.

If anyone has any of the pressure sensors to sell let me know, otherwise once I've confirmed that is the fault with my tank, I'll probably order 10 of them, sell the other 9 and fix my original tank.

Before ordering new pressure sensors and once you have your old tank off the car you should check the pump is still working and putting out sufficient pressure. There is information in this thread on how to do this.
