My car has a manual transmission.
Experienced mechanics share their insights in answering this question :
The DPF light relates to the diesel particulate system in your vehicle which includes a filter in the exhaust system that is designed to capture excessive soot and carbon that is a bi-product of the diesel combustion process. Over time, this filter will build up with excess soot and carbon deposits. Diesel engines are designed to combat this by raising the exhaust temperatures to burn off the excess buildup as you drive at higher speeds. This is called passive regeneration. When the light comes on, this means that the soot levels have reached a critical point (usually around 45-50%) indicating that the system needs to burn off this excess buildup by taking the vehicle on the highway and driving at speeds above ~40 mph or more which will help to raise the exhaust gas temperatures to burn off the excess build up. If this light is ignored and the driver continues to drive at lower speeds, this may cause the computer to put the vehicle into a "limp mode" in an effort to prevent further damage to the exhaust filtering system. I would suggest having a professional from YourMechanic come to your location to take a look at your vehicle.
How to Identify and Fix Common car Problems ?
Our sources include academic articles, blog posts, and personal essays from experienced mechanics :
DPFs have been fitted to diesel cars as standard since 2009, when the Euro 5 exhaust emissions legislation was brought in to help lower car CO2 emissions.
DPFs are only found on diesel engine vehicles. If your car is a petrol or gasoline powered engine, then your car will not have a DPF as there is no need for one. Diesel engine cars are preferred by many because they are efficient over long distances.
Drive at least 60Km/hr @ engine speed between 1800-2500rpm, at least 15 minutes until light goes out.
These problems often occur from VW vehicles doing short distances at low speeds, which doesn`t allow the DPF filter temperature to burn the soot. Often leaving a blockage, resulting in the VW DPF filter to be cleaned or replaced.
Engine design for the generation-two TDIs, or 2012–2014 Passats, differs from the third generation`s but still uses DEF to curb emissions, so the fix for those vehicles will likely follow the same path as the 2015 models, relying on greater DEF dosing to lower NOx emissions.
If I were going to buy one, which years of TDIs should I be careful to avoid? Reviewed by Shannon Martin, Licensed Insurance Agent. , you should typically avoid models from 2009-2012. The problem with TDIs dates back to the 2014 Dieselgate scandal.
Do all diesel cars have DPF problems? All diesels built from 2009 onwards will have a DPF, and some diesels built before this will have one as well.
Can I Remove The Diesel Particulate Filter? Under no circumstances should you remove a DPF! Remember, if a car was designed with a DPF, it is illegal to drive such a car without one fitted. The main reason is that without a Diesel Particulate Filter, your car will not meet its specified emissions standards.
If a filter has been removed, the car will fail its MOT. Removing the DPF will sometimes cause the warning light to glow – and this itself is an MOT failure point: no dashboard warning lights should remain on during the test.
It`s widely accepted that a DPF should last about 70,000 to 85,000 files (before the fix). The negative effect of emissions “fix” on the DPF filter should see its lifespan cut in half. A side effect of increased DPF regeneration is higher fuel consumption.
There are several ways to clean your DPF filter, you can either clear it yourself by burning the soot away or have it cleaned professionally by a garage. If the blockage persists, you will likely need to replace your DPF filter, which can be costly.
A blocked DPF can cause severe damage to your engine. This is because your engine is having to work a lot harder to vent the exhaust fumes that your blocked DPF is failing to. This can lead to weakened acceleration, increased fuel consumption, and the risk of leaks.
Starting in the 2009 model year, Volkswagen Group began migrating its light-duty passenger vehicle`s turbocharged direct injection (TDI) diesel engines to a common-rail fuel injection system.
DEF was introduced in 2010 when the Environmental Protection Agency (EPA) tightened its emission standards on diesel machines. It is part of the Selective Catalytic Reduction (SCR) system, which drastically reduces the amount of pollution emitted from vehicles.

I Cannot Screw On Oil Filter.
You are using the correct filter. I looked at the photos that you sent but the photos do not show the entirety of the threads. Even if such are shown "clearly", when it comes to threaded parts, it only takes a fairly minor defect in threads to make assembly difficult. If you cannot visually detect any gross amount of damage to the threads, the thing to do is manipulate the oil filter as you attempt to thread it on. That usually works. Given your description, in your case, it would appear that there is some very minor defect, perhaps a metal splinter or the like, that is preventing the engagement of the first thread in the filter. That is not exceptional (it happens) and thus to get it to engage you will just have to inspect and try again. Don’t force it though. With reasonable measures, if you truly cannot get the filter to engage, the external threads will have to be restored. If you have enough access, you can gently use a thread file or use the appropriate die. If you want these steps performed by a certified Mechanic, dispatched by YourMechanic right to your location, please request an oil filter base repair/installation and the responding certified mechanic will get this resolved for you. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.
2012 Mitsubishi 2.4 DI double cab diesel – fuel filter warning light came on and I remover the draining screw and drained the filt
Hi there. A warning indicator light is triggered when a sensor notices a fault and creates an error code; which is stored in the ECU of a vehicle until the issue is resolved. In most cases, the error code needs to be cleared from the ECU in order for the light to be removed. I would recommend having a professional mobile mechanic come to your location and complete a warning light inspection, so they can clear the codes and verify that the issue has been resolved. While they are there, if the light still remains, they can identify what steps are needed to fix this issue.
How reliable is the diesel fuel pumps on the 2016/2017 Ram 2500 Trucks? What is the life expect of the diesel fuel pump for the Ra
Hi there. The last time I noticed problems with Dodge Ram diesel pickup diesel fuel pumps was about 5 years ago. The issue was actually related to the wiring of the fuel pump as opposed to the pump itself. Although there are always individual issues that pop up from time to time with different trucks, in general, I’d say the Dodge diesel fuel pump made today is rather reliable. If you’re looking to make a new truck purchase, it might be a good idea for you to seek out third party truck reviews to get more information and allow you to make a more informed decision.
Does diesel grade #2 (with more sulfur) clean injectors better than grade #3?
Hello. You should use the number 2 diesel fuel only. The number 3 diesel fuel is not as good as number 2 diesel. The manual is letting you know that you can use the lower grade fuel as a minimum. The number 2 diesel is better since it has better lubrication properties and less injectors clogging issues.
To replace a fuel filter or not ? Vehicle had no fuel when bought; added fuel & it started, but should the filter be changed…
Hello, thank you for writing in. Your head is in the right place. While gas these days is held to some better standards, its very possible to collect debris in the tank over time. Considering the mileage on the vehicle, replacing the fuel filter is a great idea anyway, and you should definitely do so. They are quick and easy to do, but you need to be careful with the fuel lines. Also make sure you install the filter in the correct direction. If your fuel pump is original, then you may want to consider replacing it as well. Running a vehicle to empty can hurt the pump. It is also a great time to inspect the tank for debris. For more help replacing either fuel component, contact our service department to schedule an appointment.
Does my new car have a dpf filter? 2011 Renault Megani 1.5 106hp
Hello. We will be happy to assist you. Not all 1.5 liter DCI engines have a DPF filter though most of them produced after 2009 do. I believe yours will have a DPF filter but it would be best to have a technician check your vehicle to verify that. If you are having problems with temperatures you may want to check your temperature sensor, located on the DPF(if applicable) The Miller oil diesel power product is great only for fuel system cleaning. It will clean the fuel lines, fuel filter and the fuel injectors but would not clean out the DPF. The fuel system cleaning will help the engine produce cleaner emissions thereafter but it will not clean the deposits already present in the DPF. A great way to have your DPF professionally cleaned is by a specialist such as www.the-dpf-doctor.com or you may purchase a product such as Wurth DPF cleaner, which is more of a DIY option. http://www.shopwurthusa.com/wurthstorefront/Chemical-Product/Miscellaneous/Diesel-Particulate-Filter-Cleaner-(Aerosal-Can—400-ml)/p/5861014500
2006 BMW oil filter gasket keeps breaking and oil leaks from oil filter. Oil leaks only after starting car in morning. PCV valve?
It sounds like you may need to replace the oil cap o-ring. If you haven’t done this before there are two O-rings to replace; a small green one on the base of the filter cap stem and the large black one that seals the filter cap (which seems to be the one you are having issues with). The large O-ring sits in a small square-shaped groove that is at the base of the oil filter cap. It is very easy to not properly seat the large O-ring because the threads for the oil cap are quite large and will accept the O-ring if you are not careful. I would suggest having a professional from YourMechanic come to your location to take a look at your vehicle.
Opinion on diesel cars
You kind of answered your own question right there. They are not smooth. Americans typically like smooth stuff and they don’t like diesels because they aren’t smooth. Plus, they can smell pretty bad. No matter what you do, diesels smell. If you’ve ever been in Mexico City, have you noticed how much it stinks? There are a lot of diesels there and they just stink the environment to high heaven. I wouldn’t want to live in a place where everybody is driving diesels because they smell. The other thing is – they are very expensive to fix when they break. People I know who’ve owned diesels that have broken down know that they cost so much money to fix that, a lot of times, they never bought another diesel car. That’s why they are not popular in the United States.
