Deposits can restrict an EGR valve, cooler or connecting pipework. Cleaning may help when contamination is the problem and the component remains serviceable.
The valve must be removed. Removal and refitting are charged separately from the cleaning price.
We assess the component and select a suitable cleaning method. Ultrasonic cleaning uses a bath for suitable removed valves; electronics, seals and the assembly's condition affect what can be treated.
Warning lights, poor running and EGR-related codes can have several causes. We discuss symptoms, codes and previous work and assess valve operation before recommending cleaning.
Start with EGR diagnostics or our free initial code scan and printout.
Once access and suitability are agreed, the valve is removed and suitable components are cleaned. Coolers and pipework can also be assessed for appropriate cleaning.
We confirm the work needed and its cost before proceeding.
Removing deposits will not repair a failed actuator, damaged wiring, a worn mechanism or a leaking cooler. If a part is unsuitable for cleaning, we discuss further testing, repair or replacement.
It can help where deposits are responsible and cleaning is suitable. A code alone does not establish the cause; the repair should be checked against the original complaint.
That depends on inspection. We can discuss intake carbon-cleaning options alongside the findings without assuming every component needs cleaning.
Read our guide to EGR operation and system checks.
Send your registration, engine, mileage and fault report. Tell us whether the valve is fitted or removed and about any earlier EGR work. We will quote cleaning, access and any further investigation.
