In this case the orifice tube is the expansion valve correct?

I am very surprised the condenser was damaged removing or installing a new aux fan. I'd be concerned about the quality of care my X was receiving.

I am going to have to make a call tomorrow and see if they are going to replace the drier/receiver. If they say they aren't going to, what do I do? Is it mandatory that it be done? Meaning are they obligated to replace it being the condenser got punctured in the process, or can they say I have to pay for that if I want it done?

If he doesn't replace the receiver/drier, have him vacuum the system for an extra 30 minutes. The longer he vacuum the system the more moisture is boil away since water boil at a lower point when it is in a vacuum.

I contacted them and they planned on replacing it

Thank you for the advice

Congrats. Good step in the right direction. We all hope everything works out fine.

Now we have to get you into DIY more...

[Nick416]

Thank you again everybody for all of your help!

I don't want to talk to soon but I picked it up and all seems well. They replaced the aux fan, condenser and drier. I drove it about 40 miles after picking it up and no overheat, no check engine light and ice cold air! Thank you everyone for all of your suggestions and advice! You are absolutely right I definitely need to get into more diy. It's expensive to fix these cars but they truly are a pleasure to drive. This is my 3rd bmw but first x5 and I love to drive everyone of them!

Update: I drove it for a little while yesterday and the service engine soon light came on. I called the mechanic and it's set to go in on Tuesday. I got in it today and started it up to run down the street and the service engine soon light wasn't on anymore. Is it normal for the light to go on then turn off? If so what can cause that?
