DPF Repairs Lothians, Scotland: Get Your Diesel Vehicle Back on the Road

If you own a diesel vehicle from around 2008 to 2009, it likely has a Diesel Particulate Filter (DPF) that helps reduce harmful emissions. However, over time, the DPF can become clogged with soot, which can lead to reduced power and even safe mode.

At Octane Tuning, we are an independent DPF specialist that can accurately diagnose your DPF problems and any underlying faults that have caused your DPF light to appear. We can also offer cost-effective solutions without involving costly repair bills.

Here are some of the services we offer:

1. DPF cleaning: We use specialized equipment to remove soot from your DPF, restoring its effectiveness.
2. DPF regeneration: We can manually or automatically regenerate your DPF, which helps to burn off accumulated soot.
3. EGR valve repair: We can repair or replace your EGR valve, which is responsible for recirculating engine exhaust gases to help control emissions.
4. Injector cleaning: We can clean your injectors, which help to deliver fuel to the engine efficiently.
5. Other DPF-related repairs: We can also diagnose and repair other DPF-related problems, such as faulty sensors or intake problems.

If you're experiencing DPF problems with your diesel vehicle, contact us today for a free diagnosis. We'll be happy to help you get your vehicle back on the road and running smoothly.

Here are some of the benefits of using our services:

1. Cost-effective: We offer competitive prices for our services.
2. Experienced technicians: Our technicians have years of experience diagnosing and repairing DPF problems.
3. Certified equipment: We use state-of-the-art equipment to clean and regenerate your DPF.
4. Guaranteed results: We stand behind our work and guarantee our results.

We are able to offer various preventative procedures to allow your vehicle to operate efficiently and safely without any further costly repairs or unnecessary replacement parts.

Based in Loanhead, Midlothian, we serve the Lothians & Borders and Northern England

EGR Diagnostics and Solutions

What is an EGR valve and what's its purpose in an engine?

Here is a simplified explanation of what an Exhaust Gas Recirculation Valve is designed to do!

As far back as 1973 vehicle manufacturers were required by law to start to reduce the amount of particle soot matter from a diesel / gasoline engine. This was a very complex and technically challenging task to develop a solution. In internal combustion engines exhaust gas recirculation (EGR) is a nitrogen oxide (NOx) emissions reduction technique used in petrol/gasoline and diesel engines. EGR works by recirculating a portion of an engine's exhaust gas back to the engine cylinders.

The EGR valve was designed to reduce exhaust NOx gas by diluting the O₂ in the incoming air stream and provide gases inert to combustion to act as absorbents of combustion heat to reduce peak in-cylinder temperatures. NOx is produced in high temperature mixtures of atmospheric nitrogen and oxygen that occur in the combustion cylinder, and this usually occurs at cylinder peak pressure.

The very early EGR valve system was developed to recycle 5% -15% of exhaust gases without affecting vehicle output, performance and economy. However, this technology did not come without problems. Recycling the exhaust gas meant effectively reburning particulate deposits mixed with oil in the engine and thereby causing deposits of carbon to accumulate and effectively cause premature engine wear. Not an ideal situation as it resulted in reduced power and significant loss of economy. Today's modern diesel engines with new updated EGR systems now recycle up to as much as 80% of exhaust gases incorporating the introduction of DPF and AdBlue technology to reduce emissions even further. Petrol engines now have PPFs fitted which are the equivalent of a DPF.

Needless to say, carbon deposits still cause the majority of EGR valve failures and an even greater volume of replacement/repairs are required due to the increased percentages of recirculated particulates.

That’s where Octane Tuning is able to assist you. By carrying out a detailed and in-depth diagnostic analysis of the engine, we are able to pinpoint the root cause of the failure and advise accordingly.

With our custom written solutions, we are able to adapt the EGR cycle within the ECU preventing further loss of power and reduced economy and unnecessary expensive repair bills. For newer vehicles still under manufacturer's warranty we can offer our specialist EGR Cleaning Service using TUNAP Automotive Chemistry approved by all the major marques.
