This is a well known problem on the 900, it is the expansion valve opening and closing (the expansion valve is opening and closing depending on theamount of refrigerant needed, i.e. it is engaged only when cooling). I know that there have been some work trying to solve this problem but do not know if it is on the market, call or visit your dealer. They will know. In the diesel engine (Europe only) there is a different type of expansion valve with a stiffer spring fot the "needle" in the expansion valve.
