What does P242F mean?
What does P242F mean?
When a P242F error code is stored, it means that the powertrain control module (PCM) has detected a level of ash restriction in the diesel particulate filter (DPF) deemed to be restrictive. Ash accumulation is a side effect of DPF filtration and regeneration.
How do you clear an Audi P242F?
I would have thought the pressure differential would show an issue if it was blocked and currently the car will throw the coil flashing light and error even if the car ignition is on and engine not started.
How do you remove ash from DPF?

How does diesel particulate filter cleaner work?
The cleaner works by reducing the combustion temperature of the soot particles. Exhaust gases will flow much more quickly through a DPF which is emptier and not filled with soot particles. This will reduce fuel consumption and mean that you can travel further without having to fill up your tank.
How do you unblock a DPF filter?
It’s very important that you consistently hold the revs and speed for at least 30 minutes (preferably more.) If you do this correctly your filter will almost certainly unblock itself. Once you have run the car very hot for a sustained period pull over and immediately switch off the car.
What happens to the ash in a DPF?
Soot is created through the combustion process and is caught inside the DPF. When the vehicle gets to the correct temperature the vehicle does a DPF regen and burns the soot to ash to lower the contents inside. The ash sits inside the DPF and slowly builds up over time until eventually they become full of ash.
What does the DTC code p242f stand for?
This diagnostic trouble code (DTC) is a generic powertrain code, which means that it applies to most newer diesel vehicles (Ford, Mercedes Benz, Vauxhall, Mazda, Jeep, etc.). Although generic, the specific repair steps may vary depending on make/model. On rare occasions, when I have discovered a stored P242F code,…
What are the symptoms of a p242f code on a car?
Symptoms of a P242F code may include: Excessive black smoke from the exhaust Higher engine temperatures Higher transmission temperatures Possible causes for this engine code include: Excessive ash accumulation in the DPF Clogged DPF pressure sensor tubes/hoses
What causes a p242d sensor to set on a diesel?
P242C & P242D Exhaust Gas Temperature Sensor (s) Circuit low – voltage on these circuits are low, which can cause the P242D to set as well – again, unlikely both would set as well as the P242F P244A Diesel Particulate Filter Differential Pressure Sensor Too Low – can set if the DPF is becoming restricted or has become completely clogged
What does the DTC code on a diesel engine mean?
Diesel Particulate Filter Restriction – Ash Accumulation What does that mean? This diagnostic trouble code (DTC) is a generic powertrain code, which means that it applies to most newer diesel vehicles (Ford, Mercedes Benz, Vauxhall, Mazda, Jeep, etc.). Although generic, the specific repair steps may vary depending on make/model.
