Is it OK to drive with DPF light on?
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.

Why is the DPF light on my 2015 Forester Foz?

Where is the DPF on a Subaru Forester?
The turbo on the diesel forester is mounted at the outlet of the DPF. On one gentle hill where the road goes from 80kph to 100kph, I usually just roll it on in 6th and it easily lopes up to 100. Yesterday, I mashed the throttle to the carpet in 6th and it just would not go past 90kph. The low end torque was missing in action.
Why is the DPF light flashing on my 2010 Subaru Forester?

Why does the DPF light come on without warning?
Most likely an oil dilution issue as it does not turn on the MIL/CEL and the flashing DPF light comes on by itself & without warning. Check your oil dilution level. Note if it’s gone just above the 10% threshold, it might go back down below that with a bit of driving from the calculated evaporation rate…until the next regen.
