Speed shop recommend a smaller filter (for a Polo) - Mann W712/52. It's only 92mm high, but the pressure relief valve spec is different, hence the BW alternative.

It is the threaded union the cooler and filter sits on that is the problem. I may not have seated it fully during engine rebuild. I spent best part of the afternoon looking (unsuccessfully) for another nut to lock up against the retaining nut hoping to wind it in further. Then I contemplated cutting about 3mm off the end of the union thread with a cutting disc.
Silly idea!
