Question, does the emissions system get checked / cleaned on the service?

Not really. Any catalytic or other reagent fluid levels will be checked and topped up/replaced if needed but otherwise it is usually only when error codes or failures happen that any remedial work is done.

The current range of e-HDI engines is a little more efficient than the 2007 C4P HDI I traded in last year, but only on a run of 20 plus miles. Because it is so efficient it has little waste heat and takes longer to warm up than the old C4P, so paradoxically is less economical on short journeys.
Citroen really do need to invest in automatic shutter technology.

Agreed. Once the thermostat opens, the returning water must be very cold.
