Seeing an restart countdown countdown on your Audi A5 dashboard is a major concern. This common issue can halt your journey, even if the tank is full. We offer a fully mobile AdBlue delete service, bringing the solution directly to your home or workplace. For a fast, no obligation quote, tell us 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, threatening to make your A5 undriveable after a set number of miles. It can be triggered by many different system faults, not just an empty tank.
A generic light on your instrument cluster indicates the Engine Control Unit (ECU) has detected a problem within the SCR system. This could be anything from the control module to the injector.
You have refilled the AdBlue tank, but the warning light and countdown persist. This often points to a failed level sensor or another component preventing the system from resetting itself.
Your A5 has detected an issue with one of its Nitrogen Oxide (NOx) sensors. These sensors are vital for monitoring the AdBlue system's performance and are a frequent source of faults.
The vehicle may significantly limit its power output to protect the engine when a serious AdBlue system error is present. This is a clear signal to get the fault addressed before a non start condition occurs.
02Our service
Our process begins with specialist diagnostic checks to accurately identify the source of the AdBlue fault. We then connect directly to your A5's Engine Control Unit (ECU) and perform a software read. This data is then expertly modified to completely disable the AdBlue system, a process also known as AdBlue removal. Some newer models have protected ECUs that require unlocking at an additional cost, which we confirm beforehand. We can perform this service at your home or work, with optional extras like performance or economy remaps available subject to suitability.

04Vehicle compatibility
Does my Audi A5 have AdBlue? It's a common question, as not all diesel versions are equipped with it. For your Audi A5, we check the registration, engine, build specification and ECU details rather than assuming fitment or service support from its age or badge. Because fitment varies by engine, year and emissions specification, the most reliable method is for us to check your vehicle's registration to confirm compatibility and support.
Whether it's an AdBlue warning, a fault that keeps returning or a restart countdown, we can check your Audi A5'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 A5. 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 common scenario usually means a component like a sensor, pump, or heater has failed within the AdBlue system. Refilling the tank won't fix the underlying hardware fault, but our software solution can bypass the problem entirely.
Yes. Our AdBlue delete software completely removes the functions that trigger the countdown timer and no start warnings from the engine's management system.
It's possible. Many newer Audi models have ECU 'Tuning Protection' which must be unlocked before we can apply our software solution. We can determine if this applies to your vehicle from its details and will always confirm any extra cost with you before booking.
Not necessarily. While it's more likely on newer models, fitment depends on the exact engine and specification. The only certain way to know is to provide us with your registration so we can check the vehicle's data for you.
SCR stands for Selective Catalytic Reduction, the technical term for the AdBlue system. A NOx (Nitrogen Oxide) or SCR fault warning simply means your car has detected a problem with this emissions control system.
Absolutely. For drivers covering high mileage, the AdBlue system can be a frequent and costly source of problems. Our software solution provides a reliable alternative to repeated, expensive repairs.
For most Audi A5 models, the entire mobile service takes between one to two hours. If your vehicle's ECU requires specialist unlocking, it may take slightly longer, but we will advise on this when you book.
Yes, we cover Reading. Our base in Slough allows us to serve London, the M4 corridor, the wider South East and much of England. Just provide your postcode and we'll confirm our availability.
