The Symptoms of a Blocked DPF
1. DPF WARNING LIGHT
The most obvious and clear symptom of a Blocked DPF is a dashboard warning light. It can be a very worrying experience when a DPF light shows up, but not to worry, if this occurs you should call us right away so we can provide the correct guidance.
The majority of vehicles are fitted with sensitive sensors that keep an eye on how the vehicle is performing, when a sensor detects a incorrect reading they will report to the car’s ECU (computer), if the correct readings are not being met your dashboard will pop up with a warning light.
2. LIMP MODE
This is what usually happens if you ignore the DPF warning light for a period of time, when you ignore the light the DPF will continue to get more blocked, so the limp-home mode will activate to prevent extensive damage and allow you to travel short distances safely. When your vehicle goes in limp mode your performance will significantly decrease, usually limiting you to a certain amount of revs to protect the vehicle.
3. REDUCED FUEL ECONOMY
Usually one of the first indicators that your vehicle is not running as it should will be a decrease in fuel economy. Once the ECU detects that there is a build up of soot starting in your DPF the vehicle will often over fuel as an attempt to raise exhaust temperatures and allow the DPF to regenerate and clear its self.
Just by keeping an eye on your average fuel consumption through the cars digital dash should give you an idea on how the vehicle is performing, if there is an unusual drop when performing similar driving it could be a sign that there could be blockages starting to build up within your DPF.
