Regen discontinued

Have you baked the filter? That's what it sounds like it needs. Although by now you may need a new one.

 

Nvm dealer would have thought of that.

 

Need to check if egr is open and make sure turbo is boosting properly need to put it in a forced regen and check all temps also what is going on with boost and 7th injector. This will be a start but it's an 09 should be relatively simple without def. to worry about

 

what happens when u do a parked regen will it do it properly. and are there any fault codes popping up or no.

 

We had the same thing in the winter the temps get to cold outside to do a regen had to park regen. But this was usually around zero outside temp.

 

The Volvo dealer here in Phoenix recommends do a DPF service ( baking) every 170 to 180K miles as PM.

 

how does the engine temp stay when you are driving
