Looking for some help and clarity on the following...
A warning light has came on in a 2010 Mini Cooper 1.6D (girlfriends car). The warning light is 'Particle Filter Additive Tank Empty'. Can someone shed some light/info on this as I've never encountered it before, not to mention hearing about it?
Can an indepenent garage sort this or will it be a main dealer job?

Cheers folks,
Sean
