Frequently asked questions about Smart/MCC EGR valve replacement & repairs
Read our answers to questions about EGR valve replacement costs, symptoms and more.
What does an egr valve replacement on my Smart/MCC involve?
Whilst there are quite obviously many different engine designs on the market, there are as many different processes to change one.
There are some basic steps though that are common
- The mechanic will physically inspect the area around the EGR valve for leaks
- A full diagnostic test will be carried out with monitoring of live data
- If deemed to be faulty and once the engine has cooled, the EGR valve will be removed and replaced
- Diagnostic checks will be rerun and codes cleared down
- Vehicle will be road tested
What are the symptoms of a failing Smart/MCC EGR valve?
An efficiently operating EGR valve is paramount to engine performance and a faulty one can make starting difficult and reduce performance considerably.
Some of the typical symptoms are
- Difficulty in starting
- Rough engine idle and stalling
- Poor running
- Reduced performance
- Higher fuel consumption
- Engine management light illuminated
- MOT failure on emissions
How long will an egr valve replacement take on my Smart/MCC?
On average, egr valve replacement times can range from 1 hour to 3 hours with an average of 1.5 hours. The time that the job takes will depend on a number of factors, like your vehicle's make and model, year, as well as other factors. Select your car at the top of this page for information on job time and cost for your vehicle through ClickMechanic.
How often should the EGR valve be replaced on my Smart/MCC ?
While there is no set lifespan for an EGR valve as soon as you are aware of any issues with the EGR, you will need to get an engine diagnostics check, even if the EML (engine management light) isn’t on. You may have experienced the light come on and then go aff the next time the engine is started and this can be a sign that the valve is beginning to stick.
Once an EGR valve begins to fail, it will expire fairly rapidly. The more the exhaust gases flow over it in a stuck position, the worse it will become. Therefore, get it checked to be 100% certain, then get it changed.
How common is an exhaust gas recirculation (EGR) valve replacement on my Smart/MCC?
With exhaust gases flowing through the unit, it will eventually succumb to the deposits of carbon and hydrocarbons etc and it will seize. Therefore replacing an EGR valve as an all too common repair.
How can I extend the life of my Smart/MCC exhaust gas recirculation (EGR) valve?
Whilst you may not think you can have any influence over this, common sense dictates that the more efficient an engine is running, the cleaner the exhaust gasses will be. Therefore regular servicing, including the fuel filter is important.
Using quality fuel with its cleansing additives can also extend the units life as a result of a cleaner burning engine as above.
Using so called EGR system cleaners that simply get poured into the fuel tank, will not directly actually clean the EGR valve, but as previously explained, a cleaner running engine = less deposits.
How much does it cost to clean EGR on Smart/MCC?
On average it can cost between £150 to £500 to clean an EGR valve, depending on the make and model of your car. Some EGR valves take a lot of time to remove and refit, sometimes up 5-6 hours, and on top of that 2 hours to clean the EGR valve.
How to stop Smart/MCC EGR valves from clogging?
Using slightly better quality diesel with additives may help prevent the EGR valve clogging up. Regular maintenance is also key to avoid EGR valve problems.
