Guys and Gals,

I used the "Search" option and I found nothing related; so please help me to understand this system:

Two months ago or so I acquired my second X5, now a 2003 X5 3.0i Sport Package (no navigation), which I had it checked by a recognized local mechanic, who gave me his diagnostic as “everything OK” including cooling system.

Yesterday I was driving trough a parking ticket boot and when I open the window, I heard knocking coming from my engine. Immediately looked at the temperature gauge, and found it all the way to red, so I quickly turned the engine off.

There was absolutely no water in the system because a hose went loose at the bottom of the radiator.

I had absolutely no warning light about low level or at least a light saying “look at your gauges, stupid”…. I remember my former 328 at least lighting the bright red square at the gauge when its radiator broke and temperature went crazy.

Does somebody have a hint about this warning system? The Dealer says (rubbing their hands) that there is no wiring going to the radiator and to wait for a penance

Help please! .....BMW Dealer here in Mexico is unfriendly and willing to take all my kid´s college savings if I let them.

regards
