Mine was done there not too long ago on the Citroen C4 picasso, same engine. Supposed to be replaced at 100k, my bag had actually perished before the fluid was done. Simple enough replacement but it was very expensive from Citroen dealer for the replacement part. Luckily, Traynors had one. For free as well.

Got a 65 plate C4 Picasso 1.6 and the warning light for the adblue came on last night on the road home from work. I picked up a 10Litre bottle of fluid today and topped up the reservoir as per the user handbook. Citroen C4 Grand Picasso 2014 2.0 HDi In the past I've always topped up AdBlue from 10L containers that I bought from a service station.

C4 (Grand) Picasso Spare Wheel Carrier. As standard, neither the C4 Picasso nor its 7-seat sister, the Grand Picasso, have a spare wheel or the tools to change a wheel; just a compresssor and a can of sealer (that goes solid in a few years). However, having discovered that a spare wheel carrier kit is available, I went ahead and bought a 2011 W6tG.
