The only place it can really be is where the unit meets the bulkhead - there are the two plastic pipes which are meant to have rubber o-rings round them before you push it all back in, I bet one of those is missing Yes

Found some pictures. Ignore the fact I've filled mine in with poo, here's where the bulkhead connector sticks out:



Pretty sure each of those should have a rubber o-ring round to make sure they seal inside these:



No o-ring = fluid all over the inside of your car.

As above, it's most likely that your O rings are still on the old matrix.

To make life easier we removed the angled plastic that goes threw the bulkhead by undoing the 2 7 or 8mm bolts and left the original angle in the bolk head! I swear mine had o-rings between the matrix snd pipes but chris's didnt and neither does the spare one I have at home!
Can only think that Chris didn't do them up tight enough or square with each other maybe, hopefully we will find out soon!

Some people have had mixed results with this method. Some have had it leak others have had it not. I'm glad that yours didn't Smile
