Hey all! Coming to my fellow BMW owners and fans for some advise. The dealer can't figure this one out! Hoping I could figure it out and walk into the dealer one day with the answer.
My 2003 325ci (E45) has a really weird A/C issue. It seems to have a mind of its own. When it works it blows cold, but in the past couple years it will stop and start working with no obvious reason.
Just like going to the doctor, my spoiled bimmer always feels better in the waiting room. I can't seem to recreate the problem at the service center and the past 4 times have been sent home with a "could not recreate customer complaint" receipt. I've even talked the shop foreman to take my car for a couple days and he said the a/c is working fine.
Ok, I am not saying my a/c is blowing cool instead of cold. When it doesn't work it has blown up to 92*F
(similar to outside temp). So beleive me its not just me being picky.
I have tried turning the air on and off via the fan speed. Turning the compressor on and off with the snowflake button, adjusted the temp, and even turning the engine off then back on. In a previous forum someone suggested it could be the speed compensator. It doesn't matter how fast or slow I am going.
On one of my runs to the Service Center I complained that the engine was making a sort of metalic tubular wirling noise (forgive my words) when the compressor kicked on. They said they replaced a couple parts that happened to have a recall and its definatley decreased but I can still faitly hear it.
They say they've tested the compressor and checked the high and low pressure and all seems ok.
Not sure what else to do, test, or advise them to look at. Could really use some help.
Heck I am even willing to hook up anyone that can solve my issue with a vacation in Orlando and Universal Studios. And its not a scam or timeshare. Just a way of thanking you for solving my problem. No strings.
