External door handle falling off!!

[Shel]

Hi guys.
Just recently taken ownership of an e53 facelift (2004) 3.0i sport auto
A couple of issues I was aware of when bought but yesterday I went to open the drivers door and the whole handle came out of its seat on one side.

Just to clarify its the pointed end (closest to the front of the car) not the part that is closest to the key hole.
The lock works fine and the handle functions fine. If I pull the handle upwards slowly it doesn't come out but is loose and feels fragile, if I pull the handle outwards and use it to pull the door open it will come out. The person that sold it has receipts of all four door handle carriers been replaced recently. Could the handle carrier replacemen have been done incorrectly and caused the issue?
The end closest to the key hole is very strong, has no play and feels solid.

Can anyone point me in the right direction of what I should be looking at doing before I take the door card off?
