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?

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...
