The exhaust aftertreatment system of a modern diesel consists of many sensors and components that interact. A DPF warning can, for example, be caused by a sensor, an EGR problem or lots of short journeys. That is why we measure first.
What we check and do
- Fault code reading – fault codes and live data from the engine and exhaust system
- Diesel particulate filter (DPF) – soot loading, differential pressure sensor and regeneration
- EGR system – operation of the EGR valve and cooler, fouling
- AdBlue / SCR – level, pump, injector, sensors and crystallisation
- Advice – a clear explanation of the cause, the solution and the price
Why diagnose first?
A fault code or a symptom does not always tell you where the problem really is. That is why we carry out targeted checks first, before replacing anything. We cannot make a definitive diagnosis remotely or over the phone; we can tell you what we are going to check and how we will go about it.
Sound familiar?
- DPF or particulate filter warning
- Car in limp mode
- AdBlue warning or countdown to start lock-out
- EGR fault
- Loss of power on a diesel
Frequently asked questions
Can a particulate filter be cleaned instead of replaced?
That depends on the cause and the condition of the filter. We first look at why the filter is clogged, so the problem does not come straight back.
My car shows an AdBlue warning, but the tank is full. What now?
Then the cause is often elsewhere in the system, for example a sensor, the pump or the injector. We read the car and take targeted measurements.
Do you remove particulate filters or EGR valves?
No. Removing or disabling emission control systems is not allowed on public roads in Belgium. We look for a solution within the rules.
