DPF CARBON CLEANING

Our on car and off car DPF carbon cleaning services are designed to restore flow and performance without unnecessary replacement. Whether it can be cleaned on the vehicle or requires removal for a full flush, we choose the most effective method for your situation. This process removes built up soot and ash, helping prevent repeat blockages and costly failures.

SENSOR
TESTING

DPF sensor testing is critical to diagnosing blocked filters, poor regeneration, and warning lights before they turn into major repairs. We carry out precise pressure and temperature sensor testing to identify faults quickly and accurately. If your vehicle is in limp mode or showing DPF issues, proper sensor testing is the first step to getting it fixed right.

SOFTWARE & CALIBRATION

DPF software and calibration play a crucial role in ensuring your system regenerates correctly and operates as it should. We diagnose and correct faulty data, reset learned values, and carry out precise recalibrations to restore proper function. This ensures your DPF system runs efficiently, reducing the risk of recurring faults and unnecessary replacements.

COMMON DPF PROBLEMS

Does this sound familiar?

 

  • DPF warning light on

  • Vehicle stuck in limp mode

  • Loss of power

  • Poor fuel economy

  • Constant or failed regenerations

  • Strong exhaust smell

  • Cooling fans running excessively

 

A blocked DPF isn’t just inconvenient, it’s the start of a much bigger problem if handled wrong.

We’ve seen vehicles stuck in regen loops, constantly returning warning lights, and cheap fixes that don’t last.

 

After years of hands on experience, we’ve expanded our expertise across:

 

 

 

HiAce • Diesel Subaru Forester • Ranger • BT-50 • Range Rover • Land Rover Discovery Sport • Hilux D4D • Amarok • D-Max 

 

 

 

 

If it’s got a DPF, we’ve got the solution.

DIESEL ENGINE TUNING

We offer expert tuning for diesel powered vehicles, optimizing performance, power delivery, and drivability. While we don’t have an in house dyno, we work closely with industry leading professionals to ensure precise, high quality tuning tailored to your engine and vehicle setup. 

Why Most DPF Repairs Fail

Most workshops treat the symptom, not the cause.

 

A blocked DPF is usually the result of another issue:

 

  • Faulty sensors

  • EGR problems

  • Driving patterns

  • Injector issues

  • Turbo faults

If you don’t fix the cause, the DPF will block again and you’ll be back where you started.

 

 

We make sure that doesn’t happen.

I came looking for an exhaust system for my old Subaru Forester 99 GT and Gordon and the guys helped me choosing the best aftermarket system to replace my rusty one. They did it really quick and were so helpful and honest with me. 100% recommended and if you have own a Subaru this is one of the best places to look for parts and getting services done. So happy I found them. Cheers
