Which Mercedes GLA diesel engine is best?

The 200 d is the balanced choice in both generations, with the 220 d adding pace and often 4MATIC. The X156 GLA 180 d's 1.5 is frugal but feels stretched on mountain roads or with a full car.

What problems do Mercedes GLA diesels have?

The particulate filter is the main worry when a car has lived on short urban trips, and the H247's AdBlue system needs healthy sensors. On the X156's 2.1, ask about injector and timing chain work at high mileage.

What DGT label does a diesel Mercedes GLA get?

A Euro 6 diesel GLA gets the C label, which still allows entry to most Spanish low-emission zones. Check the paperwork, as some early X156s may be registered as Euro 5 and carry B.
