Why Ford Transits Have AdBlue Problems
The Ford Transit (2016-2025 models) is one of the UK’s most popular commercial vans. But it has a reputation for frequent AdBlue system failures.
Why Ford Transits Are Prone to AdBlue Faults
- 🔧 High mileage: Transits often do 80,000-150,000 miles. AdBlue pumps fail after 100,000 miles.
- ❄️ Winter use: Delivery vans operate in freezing temperatures. AdBlue crystallizes, damaging pumps and heaters.
- 🚚 Stop-start driving: City delivery routes = constant stop-start. Stresses AdBlue system.
- ⚡ Electrical issues: Ford’s wiring harness corrodes easily. Causes sensor and pump faults.
- 💧 Contamination: Cheap AdBlue or water in tank damages pump and injector.
Result: Ford Transit owners experience AdBlue faults 2-3x more often than Mercedes Sprinter or VW Transporter owners.
Which Ford Transit Models Are Affected?
- 🚐 Ford Transit Custom (2016-2025): 2.0 EcoBlue diesel
- 🚐 Ford Transit (2016-2025): 2.0 EcoBlue diesel
- 🚐 Ford Transit Connect (2018-2025): 1.5 EcoBlue diesel
Note: Pre-2016 Transits don’t have AdBlue systems (Euro 5 engines).

Ford Transit AdBlue Fault Warning Signs
If you see these symptoms, your Transit has an AdBlue fault:
Dashboard Warning Light
“AdBlue system fault” or “Emissions system fault” message. Amber or red warning light.
Limp Mode (56mph Limit)

No Start Countdown
“500 miles until no start” message. Countdown decreases. Engine won’t start at 0 miles.
Rough Idle
Engine shakes at idle. Misfires. Hesitation when accelerating. Feels underpowered.
Won’t Start
Engine cranks but won’t start. Or starts then immediately stalls. “AdBlue empty” warning.
Black Smoke from Exhaust
Unburnt fuel exits exhaust. SCR system not working. No AdBlue injection.

Ford Transit AdBlue Problems: FAQs
Q: Why does my Ford Transit keep having AdBlue problems?
A: Ford Transits have high mileage (80,000-150,000 miles), operate in harsh conditions (winter, stop-start), and have known electrical issues. AdBlue pumps fail every 2-3 years on high-mileage Transits.
Q: How much does Ford Transit AdBlue pump replacement cost?
A: £400-£600 including parts, labor, and diagnostic. Mobile service available (we come to you). Alternative: AdBlue delete from £150 (permanent).
Q: Can I drive my Transit in limp mode?
A: Technically yes, but not recommended. Speed limited to 56mph. Poor acceleration. Engine won’t start once countdown reaches zero. Get it fixed within 24-48 hours.
Q: What is the most common Ford Transit AdBlue fault?
A: AdBlue pump failure (60% of cases). Symptoms: limp mode, warning light, no start countdown. Repair cost: £400-£600. Alternative: delete from £150.
Q: How long does Ford Transit AdBlue pump last?
A: 80,000-120,000 miles on average. High-mileage delivery vans often fail sooner (60,000-80,000 miles). Once replaced, expect another 2-3 years before next failure.
Q: Is AdBlue delete worth it for Ford Transit?
A: Yes, especially for high-mileage vans. Delete costs £150-£250 (one-time). Repair costs £400-£600 (every 2-3 years). Over 3 years, delete saves £1,600-£2,700.
Q: What fault codes indicate Ford Transit AdBlue pump failure?
A: P20BA (reductant pressure too low), P2BAA (pump control circuit), P20E8 (SCR efficiency), P204F (system performance). Multiple codes usually mean pump failure.
Q: Can I fix Ford Transit AdBlue problems myself?
A: Not recommended. Requires specialist diagnostic equipment, ECU programming, and system bleeding. DIY attempts often cause more damage. Professional mobile service recommended.
Q: Will Ford Transit AdBlue delete affect MOT?
A: Possibly. MOT testers check emissions. Most Transits pass (no visible smoke test for diesels). But technically illegal. Risk: 5-10% fail rate.
Q: How do I prevent Ford Transit AdBlue problems?
A: Use quality AdBlue (Shell, BP, Texaco). Keep tank above half full. Service heater before winter. Check for fault codes regularly. Or delete the system (£150-£250, permanent).
