Some VW use it also.

The Mazda CX-5 2.2 diesel has been euro6 since 2012 without adblue.

But does it work in normal driving, as opposed to the standard emissions tests? I read that manufacturers can detect when an engine is being emissions tested, and reduce emissions accordingly! In contrast on the road modern diesels do not behave as claimed.

This was true about 1970 in the US but was firmly stamped upon-it is no longer true.The current regulations/directives state that the inspecting authority must satisfy themselves that the vehicle will operate normally on the road as well as in the laboratory-they also check RANDOM PRODUCTION vehicles.

BMW have also had it on some models for a year or 2.

The 1.6 petrol in the current multispace is an old tech engine, it's considered reliable but lacks the low torque you need in a car the size of a berlingo multispace if your carrying loads.

If the headache adblue on lorries can be is anything to go by, then an out of warranty car so equipped might be an interesting development, no doubt by passable, even quietly switchable when the aftermarket tuners currently de-dpfing get to grips with the system.
