What we do
Mobile AdBlue Delete & Removal for Your Jaguar XJ
Our mobile specialists can assess your enquiry using your vehicle details and explain the available AdBlue service options. Once suitability, price and an appointment have been confirmed, we arrange attendance at an appropriate location.
The 2016-model-year facelift introduced the uprated 300PS diesel with explicitly documented urea-injection SCR. It went on sale in autumn 2015, so calendar-year 2015 registrations must not be confused with model-year 2015 vehicles. The diesel XJ50 anniversary variant was subsequently released in 2018 in standard- and long-wheelbase forms.
Jaguar XJ X351 facelift (2016 onwards): AdBlue and SCR
- Diesel engines: 3.0-litre twin-turbo V6 diesel, 300PS, eight-speed automatic.
- SCR/AdBlue fitment confirmed for this version. We still check your registration before quoting.
Specialist AdBlue Removal and Technical Overview
Our Jaguar XJ AdBlue Delete service involves a sophisticated software recalibration of the Engine Control Unit (ECU). By opting for AdBlue Removal, the vehicle no longer relies on the complex network of sensors, pumps, and injectors that frequently fail on the XJ platform. This process stops the 'No Start' countdown and prevents the car from entering a restricted performance mode (Limp Mode). Because we are a mobile service, we carry out this work at your home or workplace, ensuring your luxury saloon is back in service without a trip to a main dealer.
Common Jaguar XJ AdBlue Delete & Removal Scenarios
On many versions, the heater element within the tank is a known weak point, often resulting in a P20BA code.

Jaguar XJ AdBlue Information
- Jaguar XJ AdBlue Delete and SCR System Fitment
The Jaguar XJ (X351) integrated SCR technology primarily in its later production years to meet Euro 6 emissions standards. This technology is commonly found on the 3.0-litre V6 Diesel engines. Determining if your specific Jaguar XJ requires AdBlue depends on the exact build date and engine configuration. We recommend providing your vehicle registration so we can verify the specific hardware installed on your car.
- Jaguar XJ 3.0d V6 (Euro 6) - Typically 2015 onwards
- Jaguar XJ LWB 3.0d V6 - Late model variants
- Engine Codes: Commonly 306DT / AJ20D variants
- SCR fitment: Verified by existence of the Blue filler cap
- Model-Specific Dashboard Warnings and Fault Codes
When the Jaguar XJ detects an issue within the SCR system, it displays specific warnings such as 'Incorrect Diesel Exhaust Fluid Quality' or 'No Engine Starts in XXX miles'. These messages are often accompanied by an amber or red engine warning light. If you've found this page, we're local to you and can assist with these errors.
- P20BA: Reductant Heater A Control Circuit Performance
- P2002: Particulate Filter Efficiency Below Threshold
- P2BAE: NOx Exceedance - Relief of Scrutiny
- P20EE: SCR NOx Catalyst Efficiency Below Threshold
- P218F: Reductant System Pumping Efficiency
Technical terms in plain English
- AdBlue (also called UREA or DEF)
- A fluid many modern diesels use to clean their exhaust. The car monitors it closely and warns you when it thinks something is wrong.
- SCR system
- The part of the exhaust that uses AdBlue. When it reports a fault, the dashboard warnings and countdown appear.
- NOx sensor
- A sensor that measures exhaust gases. A faulty reading is one of the most common reasons the warning appears.
- ECU
- The vehicle's main computer. Our service is software work carried out on it, at your vehicle.

Ask an AdBlue Specialist on WhatsAppJaguar XJ: questions owners ask us
Does my Jaguar XJ have AdBlue?+
Not all versions are equipped with it. Send us your registration and we will check your specific vehicle.
Can you help with a no-restart countdown on my Jaguar XJ?+
Yes. Please get in touch the moment the countdown starts and let us know how many miles are left. It is always better to schedule a visit before the counter hits zero, after which the car will not restart.
Is AdBlue Removal the same as AdBlue Delete?+
Yes, they are. Both terms describe the same software-based service.
Do you come to me?+
Yes, we do. Our service is fully mobile, covering all of England. We can visit you at home, your workplace, or another suitable location.
How do I get a quotation?+
For a quote, please send us your vehicle's registration, your postcode, and a picture of the dashboard warning. You can do this via WhatsApp, by calling us, or by using the form on our website. We will then check if your vehicle is suitable and provide a fixed price before arranging an appointment.
Does the Jaguar XJ X351 facelift (2016 onwards) use AdBlue?+
Yes. The X351 facelift 3.0-litre twin-turbo V6 diesel, 300PS, eight-speed automatic diesel versions use SCR with AdBlue. Send your registration so we can confirm your exact engine before quoting for AdBlue Delete and Removal.
Does every Jaguar XJ use AdBlue?+
No, not every model. AdBlue was introduced to the Jaguar XJ 3.0 Diesel range primarily from 2015 onwards to comply with Euro 6 standards. Earlier 3.0d models and petrol versions do not use SCR technology. Please send your registration to confirm if your specific X351 model is equipped with an AdBlue system.
Which Jaguar XJ engines and years have SCR?+
SCR is most commonly found on the 3.0 V6 Diesel engines produced between late 2015 and the end of the XJ (X351) production run. While some 2015 models may be Euro 5, the majority of '65' plate vehicles and newer will feature the AdBlue tank and associated sensors.
What does an AdBlue warning mean on my Jaguar XJ?+
An AdBlue warning on your Jaguar XJ indicates a system fault, low fluid levels, or incorrect fluid quality. Unlike a simple low fuel light, these warnings often trigger a non-reversible countdown. If the countdown reaches zero, the Jaguar software will prevent the engine from starting until the fault is rectified.
What can cause a no-start countdown on a Jaguar XJ?+
The countdown is usually triggered by a detected failure in the NOx sensors, a faulty AdBlue pump, or a failed tank heater. In some cases, even after refilling the fluid, the Jaguar XJ fails to register the new level, maintaining the 'No Start' message due to software errors or sensor drift.
What information do you need to quote for my Jaguar XJ?+
We require your vehicle registration number and your postcode. The registration allows us to identify the specific ECU version and SCR hardware installed on your Jaguar XJ, while the postcode helps us allocate the nearest mobile technician to your location for a prompt response.
Can you attend my postcode for my Jaguar XJ?+
Yes, we are a mobile specialist service. If you've found this page, we're local to you. We provide coverage across a wide range of UK postcodes, visiting your home or place of work to carry out the AdBlue Delete, saving you the hassle of recovering a non-starting vehicle.
What warranty applies to the agreed work?+
Our Lifetime Software Warranty applies to the software work on that vehicle. If the covered software work develops a problem, we correct it again.
How do I send a fault code or photo by WhatsApp?+
You can use the WhatsApp button on our website to instantly connect with a technician.
Do you replace AdBlue parts on the Jaguar XJ?+
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 the Jaguar XJ 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.
