This afternoon we took a quick trip out to Hewaswater Engineering, near St Austell, to resolve an AdBlue countdown fault on a Range Rover Evoque 2.0D. We’ve seen a lot of these systems playing up recently—mostly on 2016–2017 models—so when this 2018 Evoque with 77k miles showed the same symptoms, we knew exactly what we were dealing with.
When Kess Won’t Talk… Flex Steps In
Normally, we rely on our faithful Alientech Kess tools for Evoque AdBlue and ECU work.
But this one threw us a curveball—Kess simply couldn’t identify the ECU properly.
That’s where having multiple tuning and diagnostic tools becomes invaluable.
Enter the Magic Motorsport Flex Tool
While we often remove the ECU and work on the bench, this time we decided to try our Magic Motorsport Flex, and it handled the job perfectly.
The Flex is particularly strong with:
- Modern vehicles
- Sophisticated ECUs
- High-security systems
- Certain performance engines
Whereas our Kess 3 kit is the bread-and-butter tool for day-to-day remapping and AdBlue mapping, the Flex fills in the gaps on vehicles that are more selective or harder to communicate with.
Fast, Clean, Reliable Results
The Flex tool made short work of the AdBlue countdown issue. One major advantage is the excellent real-time feedback it provides during the writing process—letting us see exactly what’s happening at every moment.
Owners never see this behind-the-scenes magic, but it’s part of how we ensure:
- Safe ECU communication
- Accurate writing
- No corruption
- No unnecessary risks
- Reliable long-term results
The Evoque left happy, fault-free, and no longer threatening to lock the owner out with a no-start countdown.
