What does DPF mean on a car?
diesel particulate filter
A diesel particulate filter (or DPF for short) is part of a diesel car’s exhaust system that’s designed to filter out harmful soot. Diesel engines produce a lot of soot when they burn fuel. This soot is what’s known as particulate matter.
When does the DPF light come on on my A6?
My A6 has a dpf regeneration cycle I think it’s called. You can tell when it does it because the engine will run hotter and the fans will often run on after the cat has stopped. I often do short journeys and twice the dpf light has come on and I have had to go on a long (15-20 min) run to clear it. That’s been in 10k miles
How long does a DPF take to recoup?
At 10k miles a year, (far more than I do) at 70.6 (D) and 51.x (i) MPG it would take around 6 years to recoup the additional cost of the Diesel (Around £2500 Extra). Now this doesn’t take into account, tax differences, insurance differences, servicing cost differences or anything like that.
When do you need DPF cleaning in a car?
When operating conditions do not allow for DPF cleaning by active or passive regeneration, the vehicle may require an operator activated parked regeneration. In order for this to take place, the vehicle must be standing still.
Which is the best way to maintain a DPF?
The key to maintaining a DPF is to ensure it’s able to regenerate itself when it fills with soot (triggering the warning light). The two types of generation include passive and active.
How often should I Blast my DPF engine?
Avoid using the car for short journeys and school runs (the type of journey where the engine doesn’t get to its normal operating temperature), ensure that you routinely take the car for at least one blast at above 50 mph (90 kph) for at least 20 minutes every few hundred miles of normal use, in order for the DPF to regenerate.
Can you use DPF short journeys and town driving?
However, there is also an additive available, which is aimed at drivers in Towns and Cities who do short trips in traffic.
How long does it take for a DPF re-generation?
In addition, the car has to be traveling at a constant speed, ideally for 15 – 20 minutes for the re-generation to be completed successfully, this is to ensure that there is a steady flow of cool air passing under the exhaust, and the DPF Filter itself.
How often should you change the DPF on a diesel car?
Our advice on buying a used diesel car is because a replacement DPF can cost between £1000 and £3000 it is important that you check the current mileage of the vehicle, and the recommended DPF replacement intervals in the vehicle manual. Most DPF’s need to be changed every 100k to 120k intervals, but some can be as low as 70k to 90k.
