Same (sort of) happened to me
i thought the clamp was too tight and could do a temporary fix.
The radiator however started leaking a couple of months later
(on the side) - clearly it was time to replace it
The plastic goes brittle due to heat after a couple of years.
Behr is the brand to use on BMWs
Try GOLDWAGEN EDENVALE, 166 Van Riebeeck Ave, Motor Car Parts & Accessories, for a replacement radiator.
