What are the symptoms of a blocked DPF filter?

What Are The Signs Of A Blocked DPF?

  • You feel a loss of power in your engine (limp mode).
  • The DPF light will appear on your dashboard.
  • Passive and active regeneration keep failing.
  • A pungent smell of diesel.
  • Automatic Stop-Start System Not Working.
  • Your car seems to be releasing an excessive amount of smoke.

Which cars have DPF problems?

Which cars have the most DPF problems?

  • Nissan Qashqai and X-Trail 2006 – current models.
  • Audi A3, A4 & A6 – 2006 to 2012.
  • Skoda Octavia & other models 2004 – 2013.
  • VW – 2006 – 20012.
  • BMW 3 & 5 Series 2004 – 2012.

Can you drive with a blocked DPF?

Driving the vehicle with a blocked DPF can seriously damage your engine / turbo and it’s not uncommon to have to replace a turbo when the warning light has been ignored for extended periods. The ash residue which remains after successful regeneration cannot be removed and will eventually fill the filter.

Can a blocked DPF damage turbo?

A blocked DPF can force exhaust gas through the smallest of gaps, including the clearances in the bearing housing VNT lever arm and turbine housing waste gate mechanisms. If this occurs, carbon build up in these mechanisms can restrict movement of the levers affecting performance of the turbo.

How do I clean my DPF myself?

Drive over 40 mph (64 kph) to begin active regeneration. Begin driving and pay attention to both the engine and vehicle speed. Try to keep the engine speed around 2500 rpm. Active regeneration increases the temperature in the DPF to turn the particles into gas which can be expelled.

Which diesel has least DPF problems?

Every diesel had to have a DPF from January 2011. We seem to get fewest reported problems from Hyundai/KIA 1.6 CRDIs and Renault/Nissan/Mercedes 1.6 dCi 130s.

What diesel cars do not have a DPF?

Since 2009, manufacturers of diesel cars have been legally required to fit all diesel cars with DPFs, so all modern diesel cars have DPFs installed. Subsequently, the only way to find a diesel car without a DPF is to buy an older diesel car under 2.5l which was manufactured before the Euro 5 regulations.

Can you unblock a DPF yourself?

If you have an automatic select the auto second gear position and drive the engine around 5,000 rpm. 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.

Can a fully blocked DPF be cleaned?

Some garages can clean blocked DPFs, in a process called forced regeneration. This usually costs around £100 and, while it’s not a 100% guaranteed fix, it’s usually successful in removing the excess soot and allowing the DPF to work and automatically regenerate again.

Is a DPF expensive to replace?

Replacing a DPF can easily cost $4000 to $8000, and sometimes more, it’s a big cost… particularly when a vehicle is out of warranty!

Does premium diesel help DPF?

Not so much in the fuel system, but in the combustion area, emission components (EGR, DPF), and intake manifold, intake valves, etc. Using a premium diesel will undoubtedly delay the formation of carbon deposits in these areas. But don’t expect miracles in regards to cleaning performance.
