You just got the car or had it awhile ?? Either way air filter is probably first thing I'd check.

Would guess it's got a heavily blocked DPF.
Check your oil-sump if there is eccessive amounts of oil in there. If that is the case, car fails to regenerate and clear out the filter for some reason, but it continues trying injecting extra diesel. Hence oil-sump fills up with diesel.

Not saying it is the case, but I had it like this on mine, and it had really bad fuel economy. However not one single "check engine" light even in this condiction.

could be it just needs a good service

air filter
oil
oil filter
fuel filter

or it could be egr
blocked bpf
collapsed cat
injectors nee a clean (could try some fuel additive)
bad fuel
sticking brakes or hand brake
turbo problems

i would start with a good service and then blank egr to test and maybe replace egr if found faulty, check brakes
