I have had vehicle serviced, new filters, including cabin filter. Also had a forced regen.
Exhaust is ok according to mechanic.
Where else do I look.
Could it be injector seals. Cheers

It could be one or more leaking injector seals. It's easy to check, just take the plastic cover off (3 × 8mm hex head screws). It should be nice and clean under there.
If a seal is leaking it coats everything with a light film of diesel which burns off as the engine gets hot, and ends up like bitumen.
Be very careful tightening the injector clamps, they look strong but they're very brittle.
