All I wanted for Christmas.....2010 1.6 CR Octavia dpf warning light...glowplug flashing.....engine revs limited to 2500rpm...VAGDPF shows Oil Ash at 54.47g....OBDEleven shows P245800 Particulate Filter Regeneration Duration Bank 1 hard fault.

EOL Service mode selected ising OBDEleven and car revs freely through all gears while driving....

An attempt made to carry out

"Service regeneration during driving" initiated via OBDEleven adaption menu .but no regeneration cycle starts.

Take it out of service mode and car returns to limp mode.

Soot is 26g

Oil ash is 54g

Time since last regen is now 1267 mins

Anyone have any ideas or experience of this failure as have now left the car with a garage who are temporarily stumped.

 

Cheers in advance. Gaz

This sounds like your DPF is well and truly blocked - Bank 1 is not responding to the standard process of regeneration.  I am assuming you have a Euro4 engine (2010) here.

 

What is your driving style like?  You do need a LONG HARD drive (100 odd miles plus) to really clear out a blocked DPF.  If the only way you can achieve this is via service mode, so be it.  Other things to continue.....use decent fuel (super diesel) or a tank cleaner such as Wynns DPF cleaner.  Drive constantly hard - lots of high revs (3000rpm and above), low gearing....the Italian tune-up.  Failing that, there are companies that are out there to clean DPF'; its never perfect.

 

The other thought is....why did this happen?  Is the car running rich for a reason?

The DPF is no where near the maximum soot mass so it should regen. Oil ash is relatively high but that's expected on a car with 120k miles.

 

Based on this Audi TSB, you may need a software update to resolve the fault: https://static.nhtsa.gov/odi/tsbs/2015/MC-10128396-9999.pdf

 

I think 9416 exists for your engine which may resolve the issue and should still be pre-emissions fix. The latest is 9980 but that will contain the emissions fix

Varaderoguy cheers for your response. Car does nowhere near the milage that it used to. 9 mile work commute is probably killing the DPF. I can put it in service mode but a request for a forced driving regen didnt seem to make ant difference. Wonder if it will passive regen in service mode if i leave it in that mode long enough?

Hi Langers i didnt take Skoda up on the offer of the emissions fix. I guess if my local garage cant do this a Skoda dealer garage will want to load 9980 patch

Update: Garage believe they have sorted the problem now. Replaced pre turbo temp sensor and DPF differential pressure switch.
