I only really use the car for short 5 mile journeys to and from workDepending on what has led the garage to conclude the dpf needs replacing 🤔 there may be other options, but without any other information it is impossible to advise in any meaningful way.
Do you do lots of short journeys?
Hi Kieran, I followed your instructions but didn't manage to get that message.Hi Kathrine. I have a 2010 Astra and I have been going into Limp mode a lot - DPF issues. It popped up on my dashboard telling me to self-clean it out and after reading the manel, it told me to take the car a 25 minute drive and keep the revs above 2500, better at low gears and high speeds. I did this and after 25 minutes a message came up saying something like "self-cleaned successful". I was going around 7-mph in 4th gear etc etc. I would suggest you try this as maybe the car just needs a good rev to clean it out. Another cause is the EGR Valve, got a 2nd hand one for mine and then you can just try the petrol/diesel cleaners, put it into the tank and take the car a good drive.
