Seeing an AdBlue warning on your Audi Q5 dashboard, perhaps with a restart countdown countdown? These system faults can be frustrating, often appearing even with a full tank. We offer a specialist mobile software solution to resolve these issues at your home or workplace. For a fixed quote, please provide your vehicle registration and postcode.
24/7 Emergency Callouts Available
Emergency Mobile AdBlue Assistance. Additional emergency callout charge applies. Subject to availability.
01Common AdBlue warnings
This is the most critical warning, indicating the vehicle will be prevented from starting after the countdown expires. It signifies a serious fault within the SCR system that requires immediate attention.
A generic but serious message that points to a malfunction somewhere in the AdBlue system. This can be caused by anything from a failed NOx sensor to a faulty pump or control module.
If you have refilled the tank but the warning persists, it suggests a system error. The fault often lies with the level sensor or the control unit not correctly registering the fluid level.
Your garage may diagnose specific fault codes related to NOx sensors or the SCR system. These sensors are a common failure point and can trigger the entire cascade of AdBlue warnings.
An active AdBlue fault will often illuminate the engine management light and put the Q5 into a reduced power mode. This is a protective measure to limit emissions and prevent further system damage.
The system uses a heater to thaw frozen AdBlue in cold conditions; heater operation does not prevent every cause of crystallisation. A malfunction with the heater element is a common cause for system fault warnings, particularly in colder weather.
02Our service
Our service begins with a full diagnostic scan to confirm the nature of the AdBlue system fault. We then perform an AdBlue Delete, also known as AdBlue Removal, by reprogramming the engine control unit (ECU). This software-only solution disables the SCR system, preventing future warnings and countdowns. Some newer Q5 models have protected ECUs that may require unlocking at an additional cost, which we confirm before starting any work. We carry this out at your home, work or another convenient location. Subject to suitability, we can also quote for optional extras like performance remaps or other software solutions.

04Vehicle compatibility
Does my Audi Q5 have AdBlue? It depends on the specific model, engine and its original emissions specification. For your Audi Q5, we check the registration, engine, build specification and ECU details rather than assuming fitment or service support from its age or badge. However, not all diesel Q5 models across the range are equipped with it. The only way to be certain and to provide you with an accurate quote is for us to check your vehicle's details using your registration number.
Whether it's an AdBlue warning, a fault that keeps returning or a restart countdown, we can check your Audi Q5's compatibility and help you arrange the right service. Our mobile technicians come to your home or workplace.
Optional extras
While arranging your mobile AdBlue appointment, you can also ask about economy or performance remapping and our additional DPF and EGR software services for your Audi Q5. We'll confirm which options are available for your vehicle.
Customer questions
Still unsure? Send us your registration and a photo of the warning on WhatsApp.
Ask on WhatsAppThis may indicate a fault in the system, not a low fluid level. Common causes include a failed level sensor, a faulty NOx sensor or an issue with the control module itself.
The vehicle's engine management system will prevent the engine from starting as an emissions control measure. Our AdBlue delete service is designed to resolve this issue.
Some protected ECUs require specialist unlocking, but this depends on your Audi Q5's ECU hardware and software, not a blanket model-year rule. We check whether it is supported and confirm any extra unlocking cost before booking.
No, it's not fitted to every diesel version. Fitment depends on the engine, its power output, and the year of manufacture. We confirm compatibility for your specific Q5 by checking its registration.
SCR stands for Selective Catalytic Reduction, which is the official name for the AdBlue system. A warning related to SCR or a NOx sensor points to a fault with one of its components, which our software solution is designed to address.
Our AdBlue software solution resolves the dashboard warnings and countdowns that can leave you stranded. It's a popular choice for Q5 owners who use their vehicle daily and want to avoid recurring system faults.
For most Audi Q5 models, the process takes between one and two hours at your location. The exact time can vary depending on the ECU type and whether it needs to be unlocked.
We are based near Slough and our mobile technicians cover London, the South East, and much of England. Coverage is subject to technician availability, which we confirm when you request a quote.
The price varies depending on the vehicle's year, engine, and specific ECU hardware. We provide a no-obligation, fixed quote once you provide us with your vehicle's registration number.
No, they are just two different names for the exact same service. It is a software-only modification to the engine's control unit.
A reset on its own usually only clears the message for a while: if the fault behind it is still there, the warning or countdown normally comes back. We don't sell resets. We read the stored codes on your Audi Q5, explain what is causing the warning and, where the vehicle is suitable, quote for our AdBlue Delete software service.
Yes. Our standard hours are Monday to Sunday, 8 AM to 8 PM. Emergency callouts are available 24 hours a day, 7 days a week, subject to location and availability. An additional emergency callout charge applies and is confirmed before dispatch.
