I took my 2006 X3 (approx. 63,000 miles) in to the dealership in July/August 2009 as my a/c was not working properly. Only one vent was blowing sort of cold air, the other 3 blowing hot air. My car was still under warranty at the time. Diagnostics test were performed or so i was told (dye test), no leak found, cause was cited as needing freon and freon was added. Temporarily fixed the problem. This summer 2010, a/c gradually stopped working and has been blowing hot air for about 1 1/2 months. Took car in again, diagnostics test performed (some sort of dye test again) this time told evaporator core is the problem. Quoted $3000.00 all in. My question is, is there a way i can determine if this problem existed back in 2009 when first brought car in for diagnosis. My thoughts are that it did exist back when i was under warranty and diagnosis was incorrect or done improperly. Any suggestions would be appreciated.

There was a leak back then too. Any time the A/C system loses refrigerant there has to be a leak. Refrigerant is not used or consumed, it is a closed system.

Bmw have a factory known problems with them especially on the x3 and x5. They should known about this. But at 63,000 miles your vehicle is already out of warranty. Maybe you can get a better deal.

You are not alone. This is a common problem. We have a 2005 x3 and have to pay
$2000 for the evaporator core. They pushed you off saying it was freon. It is a 12 to 15 hour repair and expensive. BMW should recall it but they know that it would cost them a mint at $2000-$2500 a pop.

Of course it was leaking the first time you had it checked, they just added refrigerant and hoped it would last until the warranty ran out, now YOU pay for it and NOT bmw. With the modern electronic leak detectors, there is NO excuse for NOT locating a leak. All they do is sniff the condensate drain under the car , that is the tube that drips water when the A/C is on and the car is parked for a few minutes, you should see a little puddle under the car. The refrigerant is heavier than air and is easily detected . My sister-in-law has had the same problem with 2 beemers . They probably instal paper thin cheap aluminum evaporators at the factory, knowing that they will fail within 3 to 5 years. It is guaranteed future profit for the service departments at the dealerships.
