What we do

Mobile AdBlue Delete & Removal for Your Mercedes-Benz Citan

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 second-generation Citan went on sale in the UK in January 2023, rather than at its earlier continental launch. The UK manufacturer's brochure specifies a 17.4-litre AdBlue tank for the 110 CDI.

Mercedes-Benz Citan Second generation, C420 (2023 onwards): AdBlue and SCR

  • Diesel engines: 110 CDI, 1,461 cc four-cylinder diesel, 95 hp.
  • SCR/AdBlue fitment confirmed for this version. We still check your registration before quoting.

Mercedes-Benz Citan AdBlue Delete and Removal Service

By performing an AdBlue Removal, we recalibrate the engine management system to no longer require input from the AdBlue pump, sensors, or injector. This effectively stops the countdown and prevents the vehicle from entering limp mode due to SCR faults. As a mobile specialist, we travel to you, meaning you don't need to worry about recovery costs if your Citan is already in a 'no-start' condition. Simply provide your registration and postcode for a fixed-price quote.

AdBlue Delete & Removal Options

Common hardware failures on the Citan involve the integrated pump unit within the tank or a crystalised AdBlue injector.

  • 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

Mercedes-Benz Citan AdBlue Information

Mercedes-Benz Citan SCR Systems by Year and Engine

The Mercedes-Benz Citan, sharing its platform with the Renault Kangoo, introduced Selective Catalytic Reduction (SCR) technology to meet Euro 6 emissions standards. While early models (W415) typically avoided AdBlue, later versions and the current generation (W420) utilise this system to reduce NOx emissions. We commonly see AdBlue components on the 1.5-litre BlueTEC diesel engines. Because specifications vary significantly based on the exact build date and market, we ask customers to provide their vehicle registration. This allows us to confirm whether your specific OM607 or OM608 engine variant is equipped with the AdBlue tank and injector system before we attend.

  • W415 Citan (Post-2018 facelift models commonly fitted)
  • W420 Citan (Latest generation models)
  • 108 BlueTEC, 109 BlueTEC, and 111 BlueTEC variants
  • 1.5L Diesel Engine (OM607 and OM608 variants)
Model-Specific Dashboard Warnings and Fault Codes

When the SCR system fails on a Mercedes-Benz Citan, the dashboard usually displays a 'Check AdBlue' message or a definitive 'No Start in XXX miles' countdown. Ignoring these warnings will eventually prevent the engine from restarting. We have listed some of the most common fault codes below. If your Citan is showing an engine management light alongside these warnings, sending us a photo of your dashboard via WhatsApp allows for a more precise assessment.

  • AdBlue Level Low / Refill AdBlue
  • Engine Start Not Possible in XXX miles
  • P20E8 - Reductant Pressure Too Low
  • P204F - Reductant System Performance
  • P207F - Reductant Quality Performance
  • P229F - NOx Sensor Circuit Performance
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 WhatsApp

Mercedes-Benz Citan: questions owners ask us

Does my Mercedes-Benz Citan 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 Mercedes-Benz Citan?+

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 Mercedes-Benz Citan Second generation, C420 (2023 onwards) use AdBlue?+

Yes. The Second generation, C420 110 CDI, 1,461 cc four-cylinder diesel, 95 hp diesel versions use SCR with AdBlue. Send your registration so we can confirm your exact engine before quoting for AdBlue Delete and Removal.

Does the Mercedes-Benz Citan use AdBlue?+

Yes, later versions of the Mercedes-Benz Citan, specifically those produced from roughly 2018 onwards to meet Euro 6 standards, use AdBlue. The 1.5 BlueTEC diesel engines are the most common variants equipped with this SCR technology. If you are unsure, check for a blue filler cap next to your diesel filler.

Which Mercedes-Benz Citan engines and years have SCR?+

SCR is commonly found on the OM608 engine variants in the W415 facelift and the newer W420 models. Earlier 108/109/111 CDI models often did not require it. Because fitment varies by exact production month, please send us your registration so we can verify the specific emissions hardware on your van.

What does an AdBlue warning mean on my Mercedes-Benz Citan?+

An AdBlue warning on your Citan dashboard indicates either a low fluid level, a system malfunction, or poor reductant quality. Unlike a simple oil light, these warnings often trigger a non-reversible countdown that will eventually prevent the engine from starting until the software or hardware fault is professionally addressed.

What can cause a no-start countdown on a Mercedes-Benz Citan?+

The no-start countdown is usually triggered by a detected fault in the NOx sensors, a failing AdBlue pump, or a blocked injector. Even if the tank is full, a component failure tells the ECU that the vehicle is no longer meeting emissions targets, forcing a countdown to prevent further operation.

What information do you need to quote for my Mercedes-Benz Citan?+

To provide an accurate quote for an AdBlue Delete, we require your vehicle registration number, your current postcode for travel calculation, and a mobile number. It is also very helpful if you can tell us the specific warning message or fault codes currently showing on your dashboard.

Can you attend my postcode for my Mercedes-Benz Citan?+

Yes, we operate a fully mobile service and can attend your home, place of work, or even the roadside if you are stranded.

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. This helps us confirm the exact fault and provide a faster, more accurate quote.

Do you replace AdBlue parts on the Mercedes-Benz Citan?+

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 Mercedes-Benz Citan 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.
