This is mentioned in FAQ but the link to the supermarket website is defunct.
So, have any more manufacturers (especially VW Group) given ther "approval" to this blended bio fuel? It is hinted elsewhere that some 100% biofuels are OK but why the problem with the 30% blend? All diesels are a 5% blend now anyway by EU edict AFAIK.

"All diesels are a 5% blend now anyway by EU edict AFAIK."
I think it's more "all diesels can contain up to 5% bio"

When I had an Audi I was given a leaftlet which stated in no uncertain terms to avoid the Morrisons Biodiesel.

All VAG engines were approved with B100 RME before 2004, as which point exhaust emission control systems started to be introduced which are not happy with biodiesel..
It should also be noted the biodiesel in Morrissons is FAME not RME. No approval was ever given for this in VAG cars as it was RME that was generally available in Germany. In other words, never tested.
I have used the Morrissons B30 FAME and B100 FAME from a local supplier in my VW with no ill effects.

Someone mentioned on here not to use them in PD engines. Seems like sound common sense to me. Paying a couple of p extra may add to a feeling of "looking after" an engine.

Tried a tank of it in my Mondeo. Subjectively it seemed to run rougher, blow more smoke and be down on power. The back of the car ( it's an estate ) was covered in soot after a long run. Haven't tried using it since. Posh chipfat imho.
