Diesel particle filter.
Sup guys this issue is giving me a headache for a long time. My understanding is take it on a motorway to clean it, I’ve done that but now it’s gone in limp mode with engine management light and the squiggly light. I was told short journeys causes this which is absurd because I don’t always take it out for an hours run a day I do a lot of short journeys in and around town. Surely this can’t be it? Sounds a bit daft to me that I can’t use my car to run errands, take the dog out etc.. The light comes on frequently. Is there an underlying issue causing this? Or is it simply short journeys?
