Please, if you’re going to use Google to diagnose your own DPF issues, do it knowing that a lot of what you read may be...lets say unhelpful. You know what they say, never let the truth get in the way of a good story!
Google will have the right answers hidden in all the wrong ones. Contact us and we will help decipher fact from fiction.
Some common myths to be aware of:
❌ 𝐀𝐧𝐲 𝐯𝐞𝐡𝐢𝐜𝐥𝐞 𝐨𝐥𝐝𝐞𝐫 𝐭𝐡𝐚𝐭 𝟐𝟎𝟏𝟎 𝐜𝐚𝐧 𝐥𝐞𝐠𝐚𝐥𝐥𝐲 𝐡𝐚𝐯𝐞 𝐭𝐡𝐞 𝐃𝐏𝐅 𝐫𝐞𝐦𝐨𝐯𝐞𝐝.Incorrect! All vehicles are to adhere to the emission control laws at the time of their manufacture. Removing any DPF for on road use is illegal.
❌ 𝐓𝐨 𝐜𝐚𝐫𝐫𝐲 𝐨𝐮𝐭 𝐚 𝐫𝐞𝐠𝐞𝐧𝐞𝐫𝐚𝐭𝐢𝐨𝐧, 𝐝𝐫𝐢𝐯𝐞 𝐭𝐡𝐞 𝐯𝐞𝐡𝐢𝐜𝐥𝐞 𝐡𝐚𝐫𝐝 𝐟𝐨𝐫 𝟑𝟎 𝐦𝐢𝐧𝐮𝐭𝐞𝐬.Incorrect! The harder you drive it the more soot it will produce. Just drive your vehicle normally out on the highway, this will complete the regeneration as long as all the components in the DPF system are working correctly.
❌ 𝐈 𝐡𝐚𝐯𝐞 𝐃𝐏𝐅 𝐩𝐫𝐨𝐛𝐥𝐞𝐦𝐬. 𝐈𝐭 𝐦𝐮𝐬𝐭 𝐛𝐞 𝐭𝐡𝐞 𝐃𝐏𝐅𝐬 𝐟𝐚𝐮𝐥𝐭.Incorrect! The DPF is a filter. If it blocks up, it's just doing its job and you may have a problem with your engine, or the vehicle is being driven on lots of short trips where a regeneration is unable to complete.
❌ 𝐌𝐲 𝐃𝐏𝐅 𝐢𝐬 𝐛𝐥𝐨𝐜𝐤𝐞𝐝 - 𝐈 𝐜𝐚𝐧 𝐟𝐢𝐱 𝐭𝐡𝐢𝐬 𝐦𝐲𝐬𝐞𝐥𝐟 𝐛𝐲 𝐣𝐮𝐬𝐭 𝐫𝐞𝐩𝐥𝐚𝐜𝐢𝐧𝐠 𝐢𝐭. Incorrect! There is a reason why a DPF will block up. There is a good chance that just replacing your blocked DPF will result in another blocked DPF. Have the vehicle diagnosed by someone who knows how DPFs work and can prevent this from happening.
❌ 𝐃𝐏𝐅𝐬 𝐚𝐫𝐞 𝐫𝐞𝐚𝐥𝐥𝐲 𝐞𝐱𝐩𝐞𝐧𝐬𝐢𝐯𝐞 𝐭𝐨 𝐫𝐞𝐩𝐥𝐚𝐜𝐞. Incorrect! In the early days when this technology was new, knowledge of these systems was not fully understood. Even the dealerships were unable to successfully diagnose the new technology. But over time the systems were learned, and diagnosis can now be pinpointed to the exact fault. DPFs can be cleaned and aftermarket units are now available, making the repair a 5th of what they used to cost to repair. If you have any issues with your DPF, make sure you find a mechanic that specialises in your make of vehicle, and knows how the DPF system works. This should make sure that the repair cost is kept to a minimum, and remember a cheap quote is not always the best option.
