01Common AdBlue warnings

Is your Audi A5 showing one of these?

Restart Countdown

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.

AdBlue System Fault Warning

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.

Warning Light Stays On After Refill

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.

NOx Sensor Fault

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.

Reduced Engine Power (Limp Mode)

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 Audi A5 AdBlue Delete & Removal 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 your Audi A5 have AdBlue?

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.

Audi A5 AdBlue help

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

Other services available for your Audi A5

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

Questions customers ask us

Still unsure? Send us your registration and a photo of the warning on WhatsApp.

Ask on WhatsApp
My A5 says restart countdown but I've refilled it. Why?

This 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.

Will the AdBlue countdown warning disappear after your service?

Yes. Our AdBlue delete software completely removes the functions that trigger the countdown timer and no start warnings from the engine's management system.

Does my newer Audi A5 ECU need unlocking?

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.

Does my 2019 Audi A5 TDI definitely have AdBlue?

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.

What is an SCR or NOx fault on my Audi A5?

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.

Is this a good solution for my high mileage company A5?

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.

How long does the AdBlue delete take?

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.

I'm in Reading, is that within your coverage area?

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.

How much does an Audi A5 AdBlue delete cost?

The price is specific to your car's model year, engine and ECU type. For an accurate quote based on your vehicle, please get in touch with your registration number and postcode.

What is the difference between AdBlue Delete and AdBlue Removal?

There is no difference. They are two names for the same software service. We digitally 'remove' or 'delete' the AdBlue system's operating parameters from the engine's software. No physical parts are ever touched or removed.

Do you offer 24/7 emergency callouts?

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.
