So got home today after a short trip and when I parked the car it was happily idling then suddenly went off. Got out and diesel was leaking from near right rear tyre from the filter. I've managed to remove the filter quite easily and I was thinking that maybe the o-ring may have just suffered a catastrophic failure. However, after doing a bit of research on this forum and others, seems like it was a common issue that the housing would crack and fail? This is my first diesel as I had a 2.5T previously with a completely different filter. I will check tomorrow and see if I can see a crack on the threads however, I have ordered a new filter and o-ring but I'm now thinking - is there any point of installing them or just try and source a new housing? Are they easily available? If indeed its the housing, did they change the design of the new housing? Thanks as always!
