As many of you know, I’m the proud owner of a 2015 diesel VRS estate. Lucky for me Skoda and the VAG group in general have ironed out many of the DPF issues that plagued earlier cars. My article regarding the Octavia iii 3 DPF was very popular so I’ve put together this little post to help out my fellow Octavia 2 ii brothers and sisters.
Unfortunately due to the aging fleet and “early” design of the DPF / exhaust system the earlier cars do seem to have many more issues with the diesel particulate filter. Our research also suggests that the DPF sensors may also be prone to failure which could be a rather misleading issue.
Fortunately I’ve been able to source a couple of little gems not available on the Skoda website. Please find below the links to the Skoda Octavia ii 2 owners Manual and also the Skoda DPF leaflet
For those not wanting to trawl the manual for the good stuff, see below inc screenshots of the DPF pages in the manual
From the Manual
Diesel particle filter (diesel engine)
The diesel particle filter separates the soot particles from the exhaust. The soot particles collect in the diesel particle filter where they are burnt on a regular basis.
If the warning light comes on, this means that soot has accumulated in the diesel particle filter because of the frequent short distances.
In order to clean the diesel particulate filter, the vehicle should be driven at an even speed of at least 60 km/h at engine speeds of 1 800 – 2 500 rpm for at least 15 minutes or until the warning light goes out with the 4th or 5th gear engaged (automatic gearbox: position S) when the traffic situation permits it. This increases the exhaust temperature and the soot particles deposited in the diesel particle filter are burnt.
Whereby the applicable speed limits must always be observed » . £ Instruments and warning lights 23 The warning light goes out after the successful cleaning of the diesel particle filter. If the filter is not properly cleaned, the warning light does not go out and the warning light begins to flash. The following is displayed in the information display: Diesel-particle filter: Owner’s manual! appears. Afterwards the engine control unit shifts the engine into the emergency mode, which only has a reduced power output. After switching the ignition off and on again the warning light comes on. Visit a specialist garage immediately
- The diesel particle filter achieves very high temperatures. Therefore do not park in areas where the hot filter can come into direct contact with dry grass or other combustible materials – risk of fire!
- Always adjust your speed to suit weather, road, region and traffic conditions. The recommendations indicated by the warning light must not tempt you to disregard the national regulations for road traffic.
As long as the warning light lights up, one must take into account an increased fuel consumption and in certain circumstances a power reduction of the engine.
- To assist the combustion process of the soot particles, we recommend that regularly driving over short distances should be avoided.
- Using diesel fuel with an increased sulphur content can considerably reduce the life of the diesel particle filter. A specialist garage will be able to tell you which countries use only diesel fuel with high sulphur content.
Here’s also the advice from Skoda in the PDF DPF leaflet
What should I do if the DPF warning light comes on?
When the light shown illuminates, it means the vehicle needs help to carry out DPF regeneration. The procedure involves the vehicle being driven in a certain way to help increase the exhaust temperature. Drive continuously for about 10-15 minutes at a speed of at least 23mph whilst maintaining an engine speed of 700 rpm or above. Higher engine speeds are perfectly acceptable where conditions allow. If the conditions described are not met and the DPF warning light does not switch off, the level of soot in the DPF will continue to increase. This will increase to a certain level, where two warning lights will appear together.
What happens if two or more warning lights come on together? i.e the DPF light and EML (engine management / warning light)
If two or more lights come on together, the DPF regeneration can only be carried out at a Škoda retailer or by Škoda Assistance. It is recommended that the vehicle is driven straight to a Škoda retailer or that you contact Škoda Assistance. Failure to adhere to this recommendation may result in reduced engine power followed by the DPF becoming blocked. If the DPF becomes blocked.
Ou advice is to get in contact with your nearest Skoda main or independent specialist dealer before you take any drastic and illegal action like having your DPF filter removed / gutted. It could well be a sensor issue or could be resolved by putting from DPF cleaning / regeneration additive in to the fuel tank. We’d also suggest heading over to one of the many owners clubs like Briskoda were fellow owners maybe able to help you figure out the best plan of action. We’ve noted that many also have access to the VDS diagnostic software which could help you pin point the issue without costly dealer diagnostic charges.
