AdBlue Pump Replacement Cost: £400-£800
The AdBlue pump is the most common failure on diesel vans. It’s responsible for injecting AdBlue into the exhaust system to reduce emissions.
Why AdBlue Pumps Fail
- 💧 Crystallization: AdBlue freezes in winter, damaging pump internals
- 🔧 Wear & tear: Pumps typically fail after 80,000-120,000 miles
- ⚡ Electrical issues: Wiring faults prevent pump activation
- 🚫 Contamination: Dirty fuel or water in AdBlue tank damages pump
AdBlue Pump Replacement Cost by Vehicle
- 🚐 Ford Transit: £400-£600 (most common)
- 🚐 Mercedes Sprinter: £500-£800 (expensive parts)
- 🚐 Peugeot Boxer: £400-£650
- 🚐 Citroën Relay: £400-£600
- 🚐 Vauxhall Vivaro: £350-£550
- 🚐 VW Transporter: £450-£700
Our mobile service: We replace your pump on-site. No need to tow your van to a garage. Same-day appointments available most weeks.
NOx Sensor Replacement Cost: £300-£700
The NOx sensor monitors nitrogen oxide emissions. When it fails, you’ll see a warning light and limp mode.
Common NOx Sensor Faults
- 🔴 Warning light on dashboard

- ❌ Difficult to start
- 💨 Rough idle

- 🚗 Peugeot/Citroën: £250-£400
Alternative: NOx sensor delete from £150 — permanent solution, no more sensor failures.
AdBlue Tank Replacement Cost: £600-£1,200
AdBlue tank replacement is one of the most expensive repairs. Tanks rarely fail, but when they do, replacement is necessary.
When Do AdBlue Tanks Fail?
- 🔨 Physical damage (accident, impact)
- 💧 Corrosion (rust from moisture)
- ❌ Cracking (age, stress)
- 🚫 Faulty heater element inside tank
AdBlue Tank Replacement Cost
- 🚐 Ford Transit: £600-£900
- 🚐 Mercedes Sprinter: £800-£1,200
- 🚐 Peugeot Boxer: £650-£950
- 🚐 Citroën Relay: £600-£900
- 🚐 VW Transporter: £700-£1,000
Why so expensive? Tank replacement requires removing fuel tank, draining system, and reprogramming ECU. Labour-intensive job.
AdBlue Heater Replacement Cost: £200-£400
The AdBlue heater prevents freezing in winter. When it fails, AdBlue crystallizes and damages the system.
Signs Your AdBlue Heater Has Failed
- ❄️ “AdBlue crystallized” warning in winter
- ⚠️ Emissions system fault (winter only)
- 🚫 Vehicle won’t start in cold weather
- 💧 Limp mode during cold months
Cost by Vehicle
- 🚐 Most vans: £200-£400
- 🚐 Premium brands (Mercedes, BMW): £300-£500
Prevention tip: Use AdBlue with anti-crystallization additive in winter to avoid this £200-£400 repair.
AdBlue Delete Cost vs Repair Cost in the UK
When people search for AdBlue delete cost, they usually want to know one thing.
Is it cheaper than repairing the system again.
In most cases the answer is yes. A typical AdBlue delete in the UK costs between £150 and £250, depending on the vehicle and ECU type.
Repair prices vary much more because the SCR system has multiple failure points. Pumps, heaters, sensors and tanks can all trigger warning lights or no-start countdowns.
If you want to see how the process works, read about our AdBlue delete service and what it involves.
Should you repair your AdBlue system or delete it? Here’s a 3-year cost comparison:
| Cost Factor | Repair (3 years) | Delete (One-time) | Savings |
|---|---|---|---|
| Initial Cost | £400-£800 | £150-£250 | £150-£650 |
| Second Failure (avg 2-3 years) | £400-£800 | £0 (permanent) | £400-£800 |
| Downtime/Towing | £100-£200 | £0 (mobile service) | £100-£200 |
| Warranty/Hassle | Ongoing risk | Permanent solution | Priceless |
| 3-Year Total | £900-£1,800 | £150-£250 | £750-£1,550 saved |
Bottom line: If your van is out of warranty, AdBlue delete pays for itself in 1-2 years and eliminates future failures.
