Audi A5 Mobile AdBlue Delete & Removal

This usually indicates a fault with a physical part of the AdBlue system, such as a sensor, the pump, or a heater. Topping up the fluid will not clear an error caused by broken hardware. Our software solution works by deactivating the system, which bypasses the faulty component.

Yes. The AdBlue delete software we apply modifies the engine's control software, disabling the functions that cause the countdown and 'no start' warnings.

This can be the case. A feature called 'Tuning Protection' is present on many recent Audi ECUs and it has to be unlocked before we can write our new software. We can find out if your A5 requires this and will always inform you of any additional charge involved before you book.

Not definitely. Although it is more common on recent cars, whether your vehicle has it is determined by its specific engine and factory setup. Letting us check your registration against our vehicle data is the only way to be sure.

SCR is the abbreviation for Selective Catalytic Reduction, which is the official name for the AdBlue system. If you see a warning for an SCR or NOx (Nitrogen Oxide) fault, it just means the car's electronics have registered an issue somewhere in that emissions control system.

Yes. High-mileage drivers often find the AdBlue system becomes a regular and expensive headache. Our software deactivation offers a dependable alternative to facing one costly repair after another.

On most Audi A5 vehicles, the whole process at your location usually lasts from one to two hours. In cases where the ECU needs specialist unlocking, it can add to the time, but we will let you know if this applies when you contact us.

Yes, our service extends to Reading. From our base near Slough, we are well-placed for the M4 corridor, London, the South East, and a large part of England. Give us your postcode, and we can confirm our availability.

Costs vary depending on your A5's year, engine, and the type of ECU it has. To give you a precise price for your car, we need your vehicle's registration and your postcode.

Yes, they are just different terms for the exact same service. It involves modifying the engine's software to digitally 'delete' or 'remove' the AdBlue system's functions. No mechanical parts are removed or physically altered.

Yes. The B10 Saloon and Avant 2.0 TDI 204 PS, front-wheel drive or quattro diesel versions use SCR with AdBlue. Send your registration so we can confirm your exact engine before quoting for AdBlue Delete and Removal.

Some UK Audi A5 diesels use AdBlue for selective catalytic reduction (SCR), particularly later Euro 6 versions. Earlier diesels may not have it, and petrol A5 models do not use AdBlue. Send your registration so we can check your vehicle's fitment.

SCR is fitted to certain late first-generation 8T/8F diesel variants and is widely used on second-generation F5 diesels introduced from late 2016, including 2.0 TDI and 3.0 TDI versions. Later badges include 35 TDI, 40 TDI, 45 TDI and 50 TDI, depending on year and specification. A badge or registration year alone is not enough to confirm the hardware; please send your registration.

A refill warning generally indicates that the AdBlue level is low. A system-fault warning indicates a detected SCR problem, which can involve dosing, fluid quality, sensors, wiring or catalyst performance. Send the exact message or a dashboard photo so we can distinguish the warning types.

A countdown can result from low AdBlue or a detected SCR malfunction. Possible causes include dosing-pressure faults, injector restrictions, NOx sensor problems and ineffective emissions treatment. At zero, affected versions may prevent restarting after the engine is switched off. The underlying condition must be resolved and the vehicle's specified recognition or reset procedure completed; clearing codes alone may not restore starting.

Please send your registration, postcode, mileage and the exact dashboard message, including any remaining countdown distance. A scan report is helpful.

Send your postcode and tell us whether the vehicle is at home, work or another location. We will confirm mobile coverage, availability and whether the location is suitable before arranging attendance.

Our Lifetime Software Warranty applies to the software work on that vehicle. If the covered software work develops a problem, we correct it again.

Include your registration, postcode and any countdown message.
