In preparation for a DIY service, I'd be interested in factual, reliable information regarding who makes the OEM filters for my Volvo, if anyone knows.

Using a non-OEM diesel filter was a potential disaster for my previous car (a Honda Accord), as a huge number of posts on Honda forums will attest... it was one of the biggest causes of loss of power and an engine warning light! Up until that point I believed that all filters from well known reputable manufacturers were equivalent.
