A 2018 Range Rover Sport AdBlue Fault
An ad-blue light on your dashboard isn’t something you want to see when you start your engine, is it?
Unfortunately, this happened to a recent client of ours when they started their Range Rover Sport.
Our client diligently maintained their Range Rover Sport, refilling the AdBlue fluid well before the prescribed service date.
So, what was causing these problems?
Luckily, our client had heard about our Range Rover experts at Shires Garage, and they brought their vehicle to us right away.
Our expert technician was entrusted with identifying and solving this multifaceted problem.
After discussing the situation with the client, work on the 2018 Range Rover Sport got underway. At Shires Garage you’re always kept in the know. We only perform work on your vehicle with your full permission.
After testing the vehicle’s performance, our specialist confirmed the AdBlue warning was present.
To get to the bottom of the issue, we needed to inspect the Range Rover Sport further.
Faults Found
Firstly, our technician inspected the Range Rover visually, checking the AdBlue system for leaks, examining the fluid level, and scanning the Range Rover dashboard for any potential causes.
Although no leaks were detected, the Range Rover Sport dashboard displayed some alarming warnings. However, these didn’t worry our technician too much, as they’d seen it all before during their time at Shires Garage.
During the next stage, our technician used our 15-step diagnostic process to identify the root cause of the Range Rover Sport AdBlue issue.
At Shires Garage, our 15-step diagnostic process is always used to diagnose issues. It allows us to spot minor problems early before they become more serious (and costly).
Diagnostic Procedure
At Shires Garage, our thorough procedures, like our 15-step diagnostic analysis, guarantee you get an efficient, cost-effective first-time fix.
We spot minor problems other garages might overlook.
After performing the visual check, our technician then used the Land Rover SDD TOPIx software to scan the vehicle’s computers for warning messages.
As Land Rover specialists, we have access to the same technical information as the main Land Rover dealerships. So we can solve any issues thrown our way.
During the diagnostic tests, the following error codes appeared on the screen:
- P231347-7B – NOx Exceedance – Diesel exhaust fluid tank empty
- P2BAE-02 – NOx control monitoring System
The appearance of these codes confirmed an issue with the Range Rover’s AdBlue system, impacting the function of the client’s car.
Yet, strangely, the vehicle’s AdBlue tank was empty, even though the client had topped it up recently.
Since no leaks were present, our expert technician refilled the vehicle’s AdBlue tank and inspected the AdBlue levels.
A pressure test was performed on the AdBlue tank, which failed. Could this be the cause of the warning message on the Range Rover’s dashboard?
Upon further examination, our expert found a stuck AdBlue injector. This indicates the injector had malfunctioned.
Thankfully, this is an issue that can be successfully fixed once identified.
At Shires Garage, customer safety is paramount. During the inspection, we performed an additional vehicle safety check and found a serious issue which needed addressing immediately.
The Range Rover’s rear brake pads and discs were extremely worn, close to the legal limit.
We informed our client of the issue, and they agreed to have them replaced.
Once the diagnosis was complete and our client had approved the additional work on the brakes, our technician proceeded with the necessary repairs.
At Shires Garage, you’re always kept in the know. We will only begin working on your vehicle once you give us the green light.
Fixing the Issue
Our Range Rover expert replaced the faulty AdBlue injector with a new unit.
We only use genuine Range Rover or high-quality equivalent parts for all repairs, maintenance, and servicing. You always get the quality needed to keep your vehicle running like new.
Once the new injector was installed, our skilled technician tested the vehicle to ensure the injector worked as it should. Our technician then proceeded to extract any air pockets within the system.
Afterwards, an AdBlue pressure assessment was performed, and we found no irregular pressures in the AdBlue system.
The problem was successfully solved.
To double-check that the issue was resolved, we thoroughly road-tested the Range Rover.
Following the Range Rover Sport’s test drive, no further problems were detected regarding the AdBlue system, and the NOx sensors were all operating correctly.
Once the AdBlue system’s issue was solved, our Range Rover specialist replaced the rear discs and brake pads, as the customer had asked, and removed all error codes from the vehicle.
Needless to say, our client was pleased to have their Range Rover Sport back in complete working condition.
