Hi Beemers,I drive a 2005 520 E60. This morning I had a prompt on my I drive that i need to refill my radiator. Took it to my mechanic and he told me that the radiator is leaking and it needs to be changed as they cannot solder the leak. Apparently he tried soldering one some time back but it started leaking after 2 days. The only choice is to change the whole radiator.Has anyone of you face the same problem and how have you rectified and what was the damage like?Plse advise accordingly.Many thanks.
