So I have a Diesel 2016 Ford Fiesta 1.5L TCDI zetec and I took it into the garage, and they said it had a dpf fault.
I went to take it for a motorway drive to get the regeneration to kick in.
Yesterday, I did about an hours drive at 70mph @ 2,200rpm and another hours drive back at just above 60mph @ about 3,200rpm.
The warning light wasn’t on at this point because it had been reset but I wanted to try get a regen going anyway.
Today the light has come back on.
I’m going to take it back out for another drive.
Is there anything specific I need to do? I read in the book between 1,500rpm and 3,000rpm but this didn’t work.
I keep reading the figures 40-60mph on various sites and I was wondering if it specifically needs to be within these speeds and 1,500rpm - 3,000rpm at the same time?
It’s still at the stage it can be cleared because my rpm isn’t limited to 3,000rpm like it has done previously.
