Aircon go on and off after X5 3.0d 2002 is turned off.
If we drive and stop and turn off the the car the aircon keep going on and off. Even when we drive, the aircon will go at a higher speed as set for about 30 or more seconds and then will go normal again. This runs the battery down.

the engine doesn't like the extra stress of the air con unit being run _ there is no way of fixing this _ unless you get a full engine overhaul or a secondhand engine and installed _ the engine is old and the extra pressure on it with the aircon it just cant handle it
is it the ecotec engine fitted 1.8 or 2.0./2.2l or the diesel 1.7 engine.. how long have you not used the air con for. not using it for a long time you can damage the pump the flown sensor. even the temperature sensor. but if the engine is trying to stall with the ac on then the pump may have a fault. ac should be run for 10min once a week no matter the weather. stops you having problems later.
The Amber Engine Icon means the same as a Check Engine Light. Your car's ECM (Computer) has stored a Trouble Code, and you will need a OBD II Reader (On- Board Diagnostic) to get the code so you can diagnose what is wrong with your vehicle. You can go to any AutoZone and they can read the code for you at no charge. You will need to diagnose and fix the problem before the Check Engine Light will turn off.
When the aircon is switch on it puts a substantial load to the engine: you need to get your car tuned to take into account the load from the aircon. Most car have a mechanism that increases the idle speed when the aircon is active: if you are unable to get your car tuned yet, try making the engine idle speed slighty faster while you have the aircon turn-on (the ajustment screw should be close to the accelator cable connection at your engine end). Don't make the idle speed too high and check by turning the aircon off and on to assess the best compromise idle speed to stop your car from almost stalling (e.g. jerking).
having driving mine for a yr now, noticed some pulleys without a belt but never thought much about it. Thought aircon just needed service till the belt for alternater, fan, power steering snapped, the mechanic told me then that the other missing one was for aircon. Two belts plus cam belt????? driving too many things ! so just check to see if all belts are still there, they snap easily `cause of the multi purposes....
