Sorry if I chose the wrong thread but my 2008 octavia is having ongoing issues regards frequent regens. Almost every drive. I was thinking along the lines of software because new (Aftermarket) DPF from Germany fitted (all values ok, except for high ash volume) Full adaptation carried out which reset ash volume, differential pressure still good, soot load miniscule. Exhaust temp sensor before DPF replaced as I thought the reading was a bit low, lower reading than the sensor after DPF. Same readings present with new sensor. (No black soot in exhaust tip) EGR valve seems to work as it should, cooler doesn't appear blocked, no engine codes ever present. I will attach a picture from my diag tool stating what software it's running currently (5760) All the help I can get is welcome cause I'm at my witts end and really don't want to map the dpf out
