Vauxhall Vivaro Diesel Particulate Filter (DPF) Problems

van using lots more fuel than it used to do,i have used a dpf cleaner in the exhaust,also had a full service,i also use a fuel adative when i fill up,taken van for a good run down motorway but still uses a lot of fuel.

Can't get it to regenerate

When I’ve drove for 5/10minutes something kicks in and start running quite noisily but I don’t know what it is !! When I stop at junctions/lights it carries on when the engine is just idling ! It even carries on after I’ve turned off...
