Subject: IDLE DIPS BELOW SPECIFICATIONS WITH AIR CONDITIONER ON
Model: 318i
During ambient temperatures in excess of 90~F, the idle may dip below specifications when the air conditioner compressor cuts in.
If normal corrective procedures do not eliminate this condition, proceed as follows:
1. Open the glove box and locate the idle control unit.
2. Inspect the idle control unit for production date code and change code as shown below.
3. If the production date is earlier than "7.83" or the change code is less than "004", remove the idle control unit.
4. Install a new idle control unit (part number 13 41 1 286 132) with:
a) Production date equal to or later than "7.83" and b) change code equal to or greater than "004".
