Quick answer
Professional cleaning ranges from £80–£150+ if accessible, but can climb if labour is extensive. DIY cleaning might only cost the price of EGR cleaner. Severe soot buildup may need full removal, increasing labour.
Detailed answer
Cleaning the EGR valve is often cheaper than replacing it, but pricing hinges on labour time and how badly sooted the system is. Here are key factors:
1. Basic Cleaning Costs
– Professional Workshop: Expect £80–£150 if the valve is relatively easy to reach. This typically covers an hour or so of labour plus specialized cleaner.
– In-Depth Removal: If your EGR is buried under other components—or if you have a complex diesel with an EGR cooler—mechanics might bill 2–3 hours of labour, pushing the cost over £200.
2. DIY Savings
– EGR Cleaner Spray: A can might only cost £10–£15. If you can remove the valve yourself, that might be your total expense.
– Time & Tools: You’ll need basic wrenches, possibly a torque wrench, and enough mechanical confidence to remove and reinstall the valve. If you’re comfortable with that, you save on labour.
3. Severity of Carbon Buildup
– Light Soot: Quick removal and a 20-minute scrub might suffice.
– Heavy Deposits: You may soak the valve or need a small brush to dislodge hardened lumps. That can add time.
– Additional Parts: If gaskets or seals are damaged, you’ll need to replace those. They’re often inexpensive but still add to the bill.
4. When Cleaning May Not Help
If the valve’s electronics are fried or the pintle seat is damaged, no cleaning will fix it. You’ll be advised to buy a new EGR valve, which often costs £100–£400+ plus labour.
5. Additional Shop Fees
While some garages bundle EGR cleaning with other intake cleaning services, others may charge a standard diagnostic fee first. Ask for an estimate or check local shop rates.
Conclusion
Professional EGR valve cleaning often lands in the £80–£150 range if access is decent and the buildup isn’t extreme. That price can climb if the part is buried or heavily clogged. A do-it-yourself approach might just run you the cost of EGR cleaner, assuming you’re comfortable removing the valve. Regardless, cleaning is usually far cheaper than a complete replacement, so if your EGR is just sooted up rather than broken, it’s a cost-effective fix.
