Euro 6 should use less ad-blue than the euro 5 ,as EGR is the primary NOX reduction part…But a lot depends how a vehicle is driven ,too much loud pedal will increase usage,as will driving uphills So there is a lot of variable …With it all being new ,possibly the EGR isn’t as effective as it should be hence using more ad blue .But that is just a thought,it isn’t gospel.I hate EURO 6 nightmare to figure out
That is not true for a volvo. They use more adblue than their euro 5 counterparts. EGR is mainly used to warm the engine up faster and keep it hot for rolling regenerations, and at low speeds where falling exhaust temperatures reduce efficiency of exhaust aftertreatment systems.
The ACM monitors adblue consumption and will give you a dash message if it is using to little or too much adblue due to a fault (or a leak!)
If anyone is wondering why their adblue pumps on their euro 6 volvos keep failing its due to a manufacturing… oversight, shall we say that allows the adblue to clog up the air pipes in the pump that control the purging of the dosing nozzle. New nozzle is out now, pump in a few weeks.
The new pumps are out in 2 weeks, but it’s going to be a long process to update them all. The problem seems to be the pump running on after the engine is switched off, causing a build up of crystal in the nozzle. Volvo seem to think this is what’s causing the high consumption

It might end up being a campaign to do them all, it might be an as and when they break. Either way its less than 2 hours for the whole job.

warcake wasn’t the adblue system a pain on the Volvos at euro5 ■■..though it was a pain on all makes lol…on euro 5 we had systems the LF and 6 had one system and the 75 up had a different system ,the LF being the best in my opinion…we had the blocked nozzle due to the dosing valve crystaling ,a modified dosing valve and software sorted that ,with NOX sensors being the ultimate pain
