Can you drive with bad DPF?
Can you ignore the DPF light and carry on driving? Technically yes, but we would not recommend it. If you ignore the DPF light and continue driving, the build-up of soot will soon reach a point whereby your car has to enter ‘limp-home’ mode in order to prevent any damage to the engine.
When does the risk of filter clogging message appear?
I intermittently get the yellow warning triangle and the risk of filter clogging message. It only happens when I’m accelerating hard and is usually when I’m hitting 40mph in 3rd gear, 50mph in 4th and 60 in 5th.
Is there a risk of particle filter blocking?
The risk of particle filter blocking shows on the dash on start up and the “service” light stays on. I’ve checked the system with a snap-on modus scanner, the only fault code stored is P1351 – pre heating relay circuit relay stuck in open position, this code does clear but comes back again on the next ignition cycle.
What to do if your DPF is getting clogged?
You could try an additive such as ‘Cataclean’ but I have no verification that it works. Your DPF has probably reached a level of soot that will not passively or actively regenerate.
What are the requirements for a Regen filter?
In order for a regen to take place there are a few criteria that have to be met, the vehicle has to have been travelling over a certain speed for a set period of time, the oil / coolant temperature has to be over a set level and most importantly the DPF soot level needs to be over a set level.

When does the DPF warning light come on?
Average rating from 137 customers who received a Warning Light is on Inspection. Diesel particulate filters are intended to reduce soot emissions by as much as 80%. When the filter fails, the DPF (diesel particulate filter) light will come on. It indicates a partial blockage in the filter.
What does the particulate filter warning light mean?
When driving at high speeds, the temperature in the exhaust gets hot enough to burn the soot. This is called passive regeneration. If the vehicle doesn’t reach high speeds frequently, the engine can burn some extra fuel to raise the temperature at lower speeds and achieve the same result. This is called active regeneration.
