Droning noise when AC is switched on

BMW states that a droning noise that occurs when the AC is switched on comes from vibrations transmitted to the cabin through the compressor intake pipe. This goes between the compressor and the evaporator. The fix, they say, is to replace the intake pipe with a re-designed one that has a damper weight on it, or baffles of some sort. You'd swear the noise is compressor bearings but the TIS specifically says replacing the compressor will not fix the problem.
I've had this noise for a while but haven't spring for the fix yet. Has anyone done this repair? Does it work? How do I make sure I get the right (re-designed) intake pipe?

i had this problem so I had BMW completely drain and refill my refrigerant with the correct amount of new oil. It fixed it 100%. I think the original oil gets wore out, dirty or low and causes the compressor to drone. My car cooled better after the drain/fill too.

Does your A/C currently blow cold?

I had the same problem and fixed it just like iansanderson did. Just get everything flushed out, and topped up with new refridgerant, check for leaks etc etc.

When it was making that noise, my A/C blew room temp air out.

Strange thing is, it blows cold. Maybe I'll just flush the whole system anyway though. How much did it cost you?

I think i was charged about $130 from the dealership. I'm sure a local shop could have done it for less, but I didn't want any headaches. I knew the dealership had probably done 2938472398 of them over the years, so they had it down pat and use the recommended oil.

Part #

Does anyone have the part number for the revised intake line for a right hand drive 07/2002 325i (assuming there's a difference between LHD and RHD)?

My car has been making this noise for over a year. The freon was topped up 9 months ago (the guy said the system was pretty much full anyway) - this cured the noise for a week but the air is still freezing cold.

UPDATE : It's been a while but I finally got around to ordering a new intake pipe. My car was built 11-2001 and according to realoem the part that is needed for cars built from 9-2001 is p/n 64 53 6 923 956. I called the local dealer and asked if they could verify if there was any re-engineered replacement part and they said no, but they a bunch of fools anyway. I'm done over there. So I took a chance and just ordered this p/n and anxiously awaited the arrival. Upon opening the box I noticed right away a large baffle hanging off the compressor side of the pipe, about the size of a lemon. Just like the TIS said, so I'm sure this is the right (re-engineered) part. I'm planning to swap it out myself, refill lost oil, then take it to an indy for evac and refill. As long as the system is open for less than 24 hours you don't have to replace the dryer.

I don't know if this is the same part for a RH drive. If your line is on the right side of the car, as seated in it, it should work.
