What the warning means
Common Symptoms and Fault Codes
Vehicles across various manufacturers, particularly those produced after 2015, often display similar symptoms when the SCR system begins to fail. You may notice an amber engine light, a message stating 'AdBlue Top Up Required' even when the tank is full, or the dreaded 'Engine Start Not Permitted' countdown. On many versions, specific fault codes such as P20E8 (Reductant Pressure Too Low), P20EE (SCR NOx Catalyst Efficiency Below Threshold), or U029E (Lost Communication with NOx Sensor) are common indicators of a failing system. Because these codes can be generic, we ask you to send your registration so we can confirm the exact software version and hardware configuration of your specific vehicle before we arrive.
- A
P20E8
Reductant Pressure Too Low
- B
P2BAD
NOx Exceedence - Reagent Issue
- C
P208E
AdBlue Injector Blockage
- D

What we offer
What we do
AdBlue Delete and Removal Options
Once the AdBlue Faults is complete, we provide a range of solutions tailored to your vehicle's specific needs. An AdBlue Delete or AdBlue Removal involves a software recalibration that instructs the ECU to stop looking for SCR data, effectively preventing the vehicle from entering limp mode or a non-start condition. This is frequently chosen for older vehicles where the cost of a new SCR catalyst or tank assembly exceeds the vehicle's value. Because we are mobile, we can perform these software-based solutions and fixes anywhere, saving you significant recovery costs.
- The AdBlue warning and restart countdown are cleared
- No more buying or topping up AdBlue fluid
- Done at the vehicle, wherever it is parked
- No Fix, No Fee: if the job cannot be completed, you pay nothing
- Eligible work carries a lifetime software warranty

Is your vehicle suitable?
- Expert AdBlue Faults for Diesel Vehicles
When your vehicle triggers a warning such as 'No Start in 500 miles' or 'AdBlue System Fault', the underlying cause is rarely simple. Our AdBlue Faults service involves a deep-level scan of the Engine Control Unit (ECU) to pinpoint the specific component at fault. Whether it is a failed NOx sensor, a blocked injector, or a malfunctioning pump, we identify the root cause before you spend thousands at a main dealer. We provide a mobile service, meaning you do not have to risk the vehicle entering a non-start state while parked at a garage.
- Specialist AdBlue fault code reading and clearing
- NOx sensor and SCR efficiency testing
- AdBlue pump and injector pressure analysis
- ECU software interrogation for countdown resets
- Vehicle Applicability and Information Needed
We provide AdBlue Faults and subsequent AdBlue Delete, AdBlue Removal, AdBlue Delete & Removal, or AdBlue Fix services for a wide range of diesel cars and vans. This commonly includes popular models from manufacturers like Land Rover, Jaguar, Citroen, Peugeot, Audi, and Mercedes-Benz. Software structures vary significantly between a 2016 model and a 2023 model, even within the same range. This allows us to check the specific ECU type, such as a Bosch EDC17 or MD1, and confirm our mobile availability in your area immediately.

Ask an AdBlue Specialist on WhatsAppQuestions customers ask us
What is an AdBlue Delete?+
An AdBlue Delete is a software-based solution where the Engine Control Unit (ECU) is reprogrammed. This recalibration tells the engine to operate without relying on the SCR system, effectively stopping all AdBlue-related error messages, countdowns, and the need for urea fluid entirely.
What is AdBlue Removal?+
AdBlue Removal is another term for an AdBlue Delete. It involves electronically removing the SCR functions from the vehicle's software. This prevents the car from entering a 'non-start' mode due to sensor failures or fluid quality issues, providing a long-term alternative to SCR faults.
What is an AdBlue Fix?+
An AdBlue Fix is a general term for resolving SCR issues.
What vehicle and postcode information do you need for a quote?+
We require your vehicle registration so we can identify the specific engine and ECU generation. Your postcode is necessary to confirm that you are within our mobile service area and to calculate the quickest arrival time for our technician.
Can I send my warning light photo on WhatsApp?+
Yes, we encourage customers to send a photo of the dashboard warning and any specific error messages via WhatsApp. This allows our technicians to perform a preliminary assessment before we even arrive at your location.
Will the AdBlue countdown disappear immediately?+
Yes, once we perform an AdBlue Delete, AdBlue Removal, a successful AdBlue Delete & Removal, or another AdBlue Fix, we reset the internal counters within the ECU. This clears the 'No Start' message and allows the vehicle to operate normally without the restriction.
Do you cover all diesel vehicles for AdBlue services?+
We cover a vast majority of diesel passenger cars and light commercial vans. However, software varies by year and manufacturer.
Do you replace AdBlue tanks, pumps or NOx sensors?+
No. We specialise in mobile software AdBlue Delete and Removal for compatible cars and vans. We do not replace tanks, pumps, heaters, injectors or NOx sensors. Send your registration and postcode and we'll confirm whether your vehicle is suitable, with the price agreed before work starts.
Do you offer 24/7 emergency callouts?+
Yes. Our normal business hours are 8 AM to 8 PM, Monday to Sunday, and we also offer a 24/7 emergency callout service across England. We confirm the price with you before a technician is sent.
