My 2017 Discovery Sport diesel has been showing the low AdBlue warning for a couple days so I finally topped it up this morning with a bottle from the petrol station, followed the instructions exactly, and now the car is displaying a message saying the DEF system needs service and it's counting down the number of restarts before it won't start at all. I'm panicking a bit because I need this car for the school run tomorrow. From what I've read this could be anything from a faulty DEF quality sensor to the system needing a reset after refilling, or worse, a problem with the DEF injector or pump. The fluid I used was the correct specification so I don't think it's a fluid quality issue. I need a transparent Land Rover repair Al Quoz workshop that can properly diagnose the DEF system and won't just tell me I need to replace everything without explaining what's actually wrong. Dynostar seems to have the right diagnostic equipment for Land Rovers and they list diesel system diagnostics. Anyone with a Discovery Sport or similar Ingenium diesel had the DEF countdown triggered after a normal refill, was it just a sensor reset or something more serious? I've heard the DEF system components are covered under extended warranty in some markets but I'm not sure about here, my car is out of the standard warranty period. Really hoping this is something that can be reset with a diagnostic tool and not a multi thousand dirham repair.
