We have a diesel 2.2 and yes we have a dpf.

Thank you Yes the fuel filter was the first thing they replaced, twice cos it happened again just after so thought it was a faulty one.

We have a 53 plate c8 and have currently got a power problem with it. The car has no power when pulling away or on hills. It is really sluggish but once we have got up to speed we're ok until we hit another hill or have to slow down. Motorways are nightmare. We've had an anti pollution fault for the last couple of years which hasn't yet been sorted as as soon as we fix one fault it says it's something else. . The diagnostic said there was no vacuum out of solinode or air flow sensor wasn't at full efficiency. So far they disconnected the airflow sensor which made no difference, and swapped the turbo solinodes over and that made no difference either. Any ideas anybody pls? Coming up to a dead end at the moment,
