BMW 525 Repair Question
A/C Expansion Valve
I would really appreciate your enlightening.
I fairly sure that the TX (thermal expansion valve) is up under the dash on that model, but why do you want to change it? It is not something that you change for no reason, if the system is not working, you should have a tech check it out, pressure readings will determine if the TX valve is faulty if so then look at replacing it, but i think that it is not a quick job to do, i may be wrong but you may be looking at quite a few hrs work to access it.

The expansion valve is inside the evaporator case! It's changed with the evap core! If you go that far...
