Hi
@Andlit, any chance you can share a bit more info on what has to be removed and how? And any photos you might have.
You said "Suspension can be lowered", do you mean air suspension? So I assume you lifted the car, lowered the suspension and then removed the subframe (I assume through the wheel arches, based on your description)?
Does anything else have to be removed in order to reach the AC pipe with the bad welding?
PS. Also, any ideas by anyone on how you can verify the leak is from the inlet pipe before you go on to take the car apart?
After I refilled the refrigerant the AC worked OK for a few days but now it works intermittently again.
I'm not even sure it's a leak, as it's a bit weird that it seems to work normally for a while and then stops. And if you stop the car for a while then it works again. If it was missing refrigerant/low pressure I would expect it to work with reduced efficiency, not work OK for a while and then stop.
Of course, I can visit the AC technicians again and they can measure how much refrigerant is left, so that's one way to find out.
