What does the red light on the DPF mean?
A red light indicates that the DPF requires regeneration immediately. The check engine or service engine soon light will come on and engine power will be reduced if the filter is not attended to. The symbol to the left indicates that the Diesel Exhaust Fluid (DEF) is low.
How does the DPF work in a diesel engine?
It should not be used to determine any warranty claims. The DPF traps the soot generated as a part of the normal operation of a diesel engine so that it is not sent into the environment. The process of regeneration enables the vehicle to clean the filter so it can trap more soot.
Why does my Jaguar XF-DPF say full DPF?
DPF systems are complicated. A warning could be a full DPF, but it could also be an erroneous message due to a problem with one of the numerous sensors which control the regen process. If you aren’t doing 15-20,000 a year with plenty of longer trips swap for a petrol.
How does the DPF calculate the soot level?
If the ECM cannot perform a regeneration, the ECM will only look at the soot mass to determine to display the Continue Driving DIC message or to set DTC P2463. The vehicle does not have a soot level sensor to determine how much soot is in the DPF. It uses algorithms to calculate the soot mass.
What does the DPF light mean on a diesel?
Diesel particulate filters are intended to reduce soot emissions by as much as 80%. When the filter fails, the DPF (diesel particulate filter) light will come on. It indicates a partial blockage in the filter. So, what is the deal with DPFs?
Can you replace the DPF filter on a diesel truck?
If you have a diesel truck, you know how important the DPF filter can be; and how expensive they are to replace when they fail. Due to environmental regulations you can no longer remove your DPF filters, but that doesn’t mean your stuck paying thousands at your local dealer – instead get a new or remanufactured DPF or DOC from Dale’s Super Store.
What to do when DPF warning lamp comes on?
When the DPF warning lamp comes on (check your handbook to see exactly what the one on your diesel looks like) it’s time to take the vehicle on a longer run, preferably on a faster road such as a dual carriageway or motorway.
Is there a problem with the DPF on a BMW?
Secondly, if a car has been BADLY remapped, then yes this could create dpf problems but done properly it isn’t an issue whatsoever. The biggest cause of dpf failure on most BMW’s is engine/egr thermostat failure and this is often missed by garages, even by BMW main dealers.
