What should I do if my DPF is not working?
If you check the manufacturer’s handbook it explains that you will need to drive the vehicle for about 20 to 25 minutes at over 2,500 RPM. 2. If the engine management light comes on and the glow plug light flashes then you will not be able to regenerate the DPF by driving. 3. ‘Limp home’ mode will engage, with a maximum of 3,000 RPM. 4.
What happens if the DPF light comes on?
If the DPF light is illuminated, the DPF will need to be regenerated. If you check the manufacturer’s handbook it explains that you will need to drive the vehicle for about 20 to 25 minutes at over 2,500 RPM. 2. If the engine management light comes on and the glow plug light flashes then you will not be able to regenerate the DPF by driving. 3.
What to do when your car goes into limp mode?
If your vehicle goes in limp mode while driving, find a safe place to stop and restart the engine. Allow the car to stay completly off for at least one minute before you restart it. In many cases, this will reset the limp mode and allow the vehicle to operate normally.
How long does DPF limp mode take in Audi A5?
Again, can’t speak for Audi, but the Renault needs 20 mins of continuous, uninterupted 50mph+ to start the regen, and maybe 10 mins to do it all. Worth noting though that your driving style should be doing this anyway, so if it’s not happening it could be a fault rather than driving style.

Why does the DPF light go out on my Volkswagen Golf?
However, diesel particulate filters must be cleaned from time to time or they will block up. Try removing the DPF and cleaning it and then see if the light goes out and the power is restored. Most of the time with these Golf’s is the filter being dirty from soot.

What does the DPF do on a diesel engine?
The diesel particulate filter (DPF) is a device designed to remove soot from the exhaust gas of the diesel engine. However, diesel particulate filters must be cleaned from time to time or they will block up. Try removing the DPF and cleaning it and then see if the light goes out and the power is restored.
Check that the EGR system is working correctly; 4. Check that the vehicle has the correct specification engine oil; 5. Check the Eolys/Cerine additive (active system); 6. When the DPF filter load reaches a predetermined level, the ECU activates a regeneration process to increase the DPF temperature to over 550˚C.
What does it mean when the DPF light comes on?
The majority of vehicle manufacturers have the same warning light sequence but you should always check the vehicle handbook to be safe. The sequence generally consists of the following steps: a) If the DPF light comes on (see image above) this means ‘regeneration’ is needed. b) Once again, read the handbook for instructions.
How does the DPF reduce the Regen cycle?
Specific to the DPF, the correct additives properly clean the engine parts and reduce the amount of particulates clogging the DPF, thereby reducing multiple regen cycles. The proper additives also help restore dynamic compression with increased ring seal.
What happens if the Regen cycle is not completed?
If the DPF regen cycle is not taking place, or not completing a full cycle, a ‘check engine’ light might illuminate on your dash. In doing so the many sensors in the system will calculate the particulates prior to the DPF and post, recognizing a lack in operation of the DPF.
