Q&A

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.
