Need help from the experienced bros here..
Aircon driver side not cold, passenger side still cold but not super cold. Read that a few suggested topping up gas first and see how..Some say not compressor if not it will blow hot air..
But there is also hissing sound from the aircon vents at the dashboard area when aircon is on, sounds like gas leaking? quite loud but not so noticeable only when radio in on a bit loud.
Few days ago PML engineer at Sime Darby Bkt Timah heard the sound and say confirm there's a leak, but also said can try gas up first and see if that works. As I was rushing I didn't get it done that day and wanted to read up more..
Any ideas what is wrong with my E90 2009? Any advise is greatly appreciated!
Hi all, just to share that I manage to solve my aircon issue , hopefully for long term.
I just had my car checked and done at one of the recommended workshop at Woodlands this afternoon.
when I told the mechanic uncle chong my symptoms - one side cold, one side not cold, and hissing sound from the air vent he straightaway said most likely not enough gas.
He drained out my old gas and true enough there was 320 units of gas left compared to the recommended 590 units. Sorry, I don't know what's the unit but its on the sticker underneath the bonnet. You can see it when u lift the hood.
Before that he had a look around under the hood and sniffed the air con vent at the dashboard to smell any gas or any oil smell. There was none so that was good news because that indicated a leak, he said.
So after 20 mins of removing and then adding new gas the car was back to being cold and no more hissing sound. Total damage: lower end of double digits. Very worth it I think to eliminate the smaller problems first.
He told me to monitor for 3 months to see if same problem came back. I thought that was a reasonable plan rather than straightaway saying there's a leak and needing to change the tubes, cooling coils etc like what the PML engineer told me - KNN!
So was at PML last week and the engineer just turned on my engine, heard the hissing sound and said this confirm leak, blah, blah. Didn't even do any tests but say must change so many things and that it will cost $2.6 to $2.8k and take 3 days to do! WTH! Lucky I didn't follow what he said.
Oh btw there's another recommended ws here also at Woodlands. Actually they are my first choice but enough to say they must be really busy and didn't need my business because they didn't get back to me.
Good luck!
