I think Carista can force a regen if needed too.
Many many years ago, I had the franchise for Forte oils in the North West. They are excellent products.Just as a side note I recommend forte dpf in tank cleaner, use it at work and it’s good I can recommend all the treatments tbh it’s cheap enough to do once every six months
Sorry to go off topic slightly, but after reading your post I ordered a bottle of Forte Advanced Formula Diesel Treatment for my Euro 5 140hp kombi, it arrived the next day and I put it in with about half a tank of fuel, to be honest I didn't think much of it after that. The van has always run perfect, touch wood.Many many years ago, I had the franchise for Forte oils in the North West. They are excellent products.
