EGR Delete Explained: Cost, MOT Rules & Benefits 2025
Tired of EGR valve clogging, poor idling, and expensive repairs? We disable the EGR system via ECU software—no cutting, no hardware removal. Mobile service across Leicester, Nottingham & Derby from £120.
Book an EGR DeleteWhat Is an EGR Delete?
An EGR (Exhaust Gas Recirculation) delete disables the recirculation of exhaust gases back into the intake manifold. This prevents carbon build-up, improves idle quality, and stops common EGR faults—all without physical valve removal.
How EGR Works
The EGR valve opens and closes to control the flow of exhaust gases back into the intake manifold. When working correctly, this reduces combustion temperatures and lowers nitrogen oxide (NOx) emissions. However, EGR systems are prone to carbon buildup, which causes:
- Reduced engine performance and sluggish acceleration
- Poor fuel economy (1-3 mpg loss)
- Rough idling and stalling
- Black smoke from exhaust
- Limp mode activation
- Expensive repair bills (£300-£600)
What Happens During EGR Delete?
- Physical removal (optional): EGR valve and cooler blanked off or removed
- ECU reprogramming: Software modified to disable EGR function
- Fault code deletion: EGR-related error codes cleared from memory
- Testing: Vehicle tested to ensure smooth running and no new faults
The process takes 60-90 minutes and is fully reversible if needed.
EGR Delete vs EGR Cleaning: Which is Better?
Confused about your options? Here's how they compare:
| Factor | EGR Cleaning | EGR Delete |
|---|---|---|
| Cost | Price on Inquiry | Price on Inquiry |
| Longevity | Temporary (6-12 months) | Permanent solution |
| Effectiveness | 60-70% improvement | 100% issue resolved |
| Frequency | Every 12-18 months | Once (permanent) |
| Warranty Impact | No impact | Voids manufacturer warranty |
| MOT Impact | No impact | See MOT section below |
| Resale Value | No impact | May affect resale |
When to Choose Cleaning:
- ✅ Vehicle under warranty
- ✅ Planning to sell within 1-2 years
- ✅ Light carbon buildup
- ✅ Want to maintain factory setup
When to Choose Delete:
- ✅ Out of warranty
- ✅ Recurring EGR problems
- ✅ Heavy carbon buildup
- ✅ Keeping vehicle long-term
- ✅ Want permanent solution
Will EGR Delete Fail MOT?
Short answer: It depends on your vehicle's age and the MOT tester.
Current MOT Rules (2025)
Diesel vehicles registered after 2014:
- Visual inspection of emissions equipment required
- Missing EGR valve may result in MOT failure
- Excessive smoke will cause failure
Diesel vehicles registered before 2014:
- Less stringent visual checks
- Focus on smoke opacity test
- EGR delete less likely to be detected
Petrol vehicles:
- EGR delete rarely checked
- Emissions test focuses on catalytic converter
The Reality
Most EGR deletes pass MOT because:
- Visual inspection is limited — testers don't remove engine covers
- Smoke test is key — if your van runs clean, it passes
- ECU programming — no fault codes = no red flags
- Tester discretion — many testers focus on safety, not emissions equipment
How to Maximise MOT Pass Rate
- ✅ Ensure DPF is still fitted and functioning
- ✅ Use quality diesel (cleans injectors)
- ✅ Service vehicle before MOT
- ✅ Choose independent garage (not main dealer)
- ✅ Avoid excessive idling before test
⚠️ Legal Disclaimer: EGR delete is not legal for road use under UK law. This information is provided for educational purposes. We recommend discussing your specific situation with our team before proceeding. Learn more about UK emissions regulations.
