Our expert insights into EGR valve replacement

What does an EGR Valve motor do?

The valve controlling your EGR (exhaust gas recirculation) controls the amount of nitrogen oxide emitted into the atmosphere by engines by recycling part of the exhaust gas back into the engine cylinders.

What are the symptoms of a malfunctioning EGR Valve motor?

A rough idle when starting your vehicle or during brief stops (i.e. low engine speeds with a warmed-up engine) can be caused when the EGR is constantly open and a continuous flow of exhaust gases goes into the intake manifold. Poor performance can be caused when the valve is open or closed. The incorrect function of the EGR valve can cause the erratic performance of your vehicle.

What happens when we do an EGR Valve Replacement replacement on your car?

There are as many different processes to change an ERG Valve.

  • 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 run and codes cleared down

  • The vehicle will be tested

Hey Fixter, how common is an EGR valve replacement?

With exhaust gases flowing through the component, it will eventually succumb to the deposits of carbon and hydrocarbons and it will ultimately seize. Replacing an EGR valve is an all too common repair.

Our reviews

Takes a lot of stress away

I would definitely recommend this company: knowing someone was keeping an eye on everything to make sure I wasn't being overcharged for parts and labour takes a lot of stress out of having the work done. I felt really well looked after. Thank you Fixter.

Kathleen Hodge, West Yorkshire

Excellent service

Excellent service. On time to pick up my car & drop it back. Full service cost £179, main dealer quoted me £700-lots different!

Muhammad, Birmingham

Total game-changer!

Just had my MOT done through Fixter for the first time. It took about 5 minutes of my time in total to book, hand over the key, and get it back when the car was returned. So I was able to carry on looking after my 2 year old. Total game-changer!

Oliver Woodford, London

No need to drive to a garage

Can't get more convenient than someone turning up, taking the car from the house for its MOT and returning it a few hours later. No having to drive to a garage (often miles from anywhere or in the middle of an industrial estate) or hanging around waiting.

Darren, Pontefract

I literally cannot fault them

This is the 3rd time I have used Fixter and I recommend to everyone. It makes getting an MOT super easy for me. Everyone I speak to on the phone is incredibly helpful and polite, and they seem to be the most cost effective. I literally cannot fault them.

What does a EGR Valve do?

The valve controlling your EGR (exhaust gas recirculation) is an important part of your car's engine. It controls the amount of nitrogen oxide emitted into the atmosphere by petrol and diesel engines by recycling part of the exhaust gas back into the engine cylinders.

Mazda

The Mazda Motor Corporation is a Japanese multinational automotive manufacturer, initially established in 1920 as a toolmaker but went on to start building cars in the 1930s.

An innovative engineering based company, Mazda has over half a million vehicles on the roads in the UK. Their popularity has made a steady climb over the past 10 years; it’s no real surprise with their provision of smartly designed vehicles and unique philosophy.

Luxurious yet affordable motoring

Mazda philosophy: Jinba Ittai—drive together

Mazda professes to create each car around its driver—engineering them to move their drivers both literally and emotionally. They call this ‘Jinba Ittai’, and this inspiration comes from Japanese tradition, a natural connection like that between a horse and rider symbolising a ‘oneness’, where the car is merely an extension of the driver.

Zoom-Zoom

Possibly Mazda’s most popular marketing slogan, established in 2000 and trickle fed through many further campaigns to help them become the well-recognised household brand they are today.

It’s fair to say that Mazda likes to do things a little differently. They make strong, bold choices, and aren’t afraid to put their efficient larger engines in their cars where other marques are working on smaller, on-trend turbocharged options.

Mazda: easy on your pocket—fun on the roads

The current UK range includes models to include tourers, SUVs and the ever-popular MX-5 convertible. Despite often seemingly going against the grain of motoring trends, Mazda makes cars that are affordable to buy, economical to run and great fun to drive.

How common is an EGR valve replacement?

With exhaust gases flowing through the component, it will eventually succumb to the deposits of carbon and hydrocarbons and it will ultimately seize. Replacing an EGR valve is an all too common repair.

How does an EGR valve work and what are the components?

The EGR valve is connected to the exhaust system by a metal tube. When the engine is running, the valve will be opened by the engine management system to allow the exhaust gases to travel up the tube from the exhaust system and back through into the inlet manifold, and afterwards back into the engine. The control of this valve is either driven directly by a solenoid on the EGR unit itself or via a hose to a solenoid on the vacuum circuit that is also opened by the engine management system. Some EGR units have a cooler as part of them, that is plumbed into the engine’s cooling system, literally to cool the exhaust gasses before they go back through. By the exhaust gasses going back into the engine, it reduces NOx (Nitrogen Oxide) content. This is because the exhaust gas reduces the actual oxygen proportion and increases the vapour content, which in return reduces the combustion temperature peak. As more NOx is produced as the temperature rises, this method actively reduces the amount created.

What are the symptoms of a malfunctioning EGR Valve motor?

A rough idle when starting your vehicle or during brief stops (i.e. low engine speeds with a warmed-up engine) can be caused when the EGR is constantly open and a continuous flow of exhaust gases goes into the intake manifold. Poor performance can be caused when the valve is open or closed. The incorrect function of the EGR valve can cause the erratic performance of your vehicle.

Common questions about booking at Fixter

Common questions about booking at Fixter

Who is going to drive my car?

All of our drivers are fully insured and your vehicle is always protected.

We put our drivers through rigorous vetting and training before they are able to drive your vehicle. All of our drivers must have at least 3 years of driving experience, hold a clean driver's licence, be over the age of 21, capable of driving both manual and automatic vehicles and pass a criminal background check.

Your vehicle will be assigned to a driver who is responsible for collecting it from your home, delivering it to the garage and returning your vehicle once all work is completed.

Sometimes we might coordinate with a garage for them to send their own driver to collect your vehicle. In this instance, you are protected as you would be if it was a Fixter driver. 

What garage will my car go to?

One of our in-house mechanics will factor in the make and model of your car, as well as the work that needs doing. They will then allocate your booking to the most appropriate Fixter garage in your area, and we’ll email you to confirm.

Here’s why only 1 in 20 garages pass our selection criteria:

  • We only choose garages registered as a Limited Company, with a minimum of 3 years of trading.

  • We assess each garage's various established affiliations (e.g. Bosch / Unipart / Garage).

  • We perform an online audit: Fixter only selects garages with at least a 4 star customer rating.

  • We make sure to visit each garage in person. Our in-house mechanics evaluate the quality of equipment, staff qualifications, capacity, and technical capabilities of selected servicing centres. Fixter only works with garages which strictly use manufacturer-equivalent parts.

  • After all requirements are fulfilled, we negotiate preferential terms with each selected (including parts, labour, oil, and MOT test rates), so we can pass it along to our customers.

What parts will be used?

All parts used in repairs and services carried out by Fixter are either manufacturer parts or equivalent. This guarantees that only the best quality parts are used in your vehicle. We offer a 12-month warranty, meaning that should anything should go wrong with the parts or labour we’ll take care of it, free of charge. 

How and when do I pay?

We take your card details when you book online, but nothing is charged to your card until all the work has been approved by our in-house experts, and satisfactorily completed.

No extra work will be carried out without your consent. If additional work is required, one of our in-house experts will call you to walk through any diagnostic reports, recommendations or additional quotes from the mechanic working on your car. We check every quote to make sure the work is required and has been fairly priced.

Note: If you need to update your payment details to pay for your booking, the team will send you a secure link to add the new card details.

How does the money back guarantee work?

If your car fails its MOT at one of our garages, but you believe that your car should have passed, you'll have the option to take your car to another garage to do a new MOT test. If your vehicle passes the MOT at another garage, we’ll refund you for the original MOT test that you carried out with us. Collection and delivery fees are non-refundable.

How does the Fixter 12-month warranty work?

All Fixter bookings are covered by a 12-month warranty on parts and labour.

If there’s a problem (with either parts or labour) up to 12 months after your booking date, we’ll sort it out for you, completely free of charge.

Just email support@fixter.co.uk or call our team on 0330 808 9527 and we’ll take care of it.

Note: this doesn't apply to an air con regas as leaks can occur at any time.

Can I cancel my booking?

We understand that things change.

If you need to cancel or change your booking, please let us know asap. Our agents spend time finding you a top-rated garage, which is then booked to take care of your vehicle. In many cases, parts are ordered in advance. As a result, we operate a 72-hour cancellation policy. If you have a confirmed booking with us and need to cancel within 72 hours of the appointment, a cancellation fee of £20 may be applied.

We want to avoid that so our agents will work with you to try and find a new appointment instead. To discuss changing or cancelling a booking, please email or phone on 0330 808 9527.

Our team works Monday to Friday from 8:30 am to 5:30 pm.
