What sort of diesel regeneration does my car have?

I have a 2013 Mercedes E250. What sort of diesel regeneration does it have? I drive 50 miles or more on main roads at least weekly.

It has an EGR and a diesel particulate filter. The DPF should regenerate passively on your longer runs and, if it hasn't regenerated enough passively, it will actively regenerate using post-injected diesel to fire itself off and burn the soot in the DPF. If it also has an SCR system requiring AdBlue then there will be a blue filler next to the diesel filler under the fuel flap.

My Vectra has been a great workhorse but now when accelerating hard the power fails at around 3000 revs. I have been advised it could be the air mass indicator that has failed. Could this be so?
I have a 2010 Volkswagen Golf Plus 1.6 turbodiesel which had its emissions 'fix' done at 43,000 miles. Is it better to get rid of it or should I just wait and see if the DPF lasts for a couple more years?
You say the underlying maintenance cost is the reason for the collapsing of diesel car prices. I'm concerned because I own a 63 reg Ford Mondeo Estate 2.0d, with 40,000 miles that I plan to keep for another...
