Once auto is in Neutral, turn the key off again. Only time key needs to be on is if you need to turn steering.

That's what I red in VADIS about drying the system, but i found nothing about "thinking" not to run your battery flat.

Default Air Con Compressornoise

Volvo S60 Dec 2003 2319cc T5 65K: Having recently replaced a timing belt, belt tensioner, belt roller and installing at the same time a new water pump. I checked all the auxiliary rollers/free wheels and I discovered that the noise I get when the engine is at idle is coming from a dry but apparently undamaged air conditioning compressor electro-magnetic clutch free wheel roller bearing.



Question: Is in situ greasing of this bearing possible and if it is will this cause any damage to the air conditioning compressor electro-magnetic clutch.

I just found this thread after doing a search....

the search was prompted by this that happened last night

...I parked the car in the garage last night, locked the car as normal then left the back door to the garage open while I was doing some gardening...walked past the garage about 45mins/1hr later to notice a wuuuuuuring sound...the cabin blower/fan was running, I unlocked the car and got in, as I put the key to the ignition it stopped and went silent.....I thought the car was possessed

lol



I'd never noticed it doing that before...so put the optimate on it overnight so it would show up if the fan came on again...obviously tonight there was no voltage drop report on the optimate.


we'd be screwed without these forums wouldn't we

My V70 does this too I thought there was something wrong with the AC switches
It did it once at my warehouse and ultimately switched itself off when the battery voltage sensor showed low battery, This forum is great for this type of info
Thanks to all.
