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

Common NOx Sensor Faults

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

- 🚐 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

- 🚫 Vehicle won’t start in cold weather
- 💧 Limp mode during cold months
Cost by Vehicle

Prevention tip: Use AdBlue with anti-crystallization additive in winter to avoid this £200-£400 repair.

| Second Failure (avg 2-3 years) | £400-£800 | £0 (permanent) | £400-£800 |
| Downtime/Towing | £100-£200 | £0 (mobile service) | £100-£200 |
