Xenon Headlamps - Intermittently Won't Switch ON

SUBJECT:

Intermittently, Xenon Lamp does not Switch On

MODEL:

E38 (7 Series) with Xenon - Vehicles produced 9/98 to 10/99

E39 (5 Series) with Xenon - Vehicles produced 10/98 to 10/99

Situation:

Xenon headlamps intermittently may not switch on, even though the light switch is in the "headlamps on" position and the ignition is switched on.

The situation occurs typically, if the head lamps are switched on when cranking the engine. The situation does not occur if the headlamps are engine

is running.

The affected headlamp(s) can only be switched on by turning the light switch to position "0", and back to "headlamps on" after waiting for at least

two seconds.

Cause:

Low starting pulse voltage at the Xenon headlamp caused by momentary low electrical system voltage resulting from the use of electrical consumers

such as the starter motor, when the headlamps are switched on, and before the engine is running. No additional starting pulse is provided in the event

that the headlamps do not turn on.

This cause only applies when the headlamps are switched on, and not in the event of xenon headlamp failure during operation.

Procedure:

In case of customer complaint, recode the lamp control module (LCM), with DIS CD version 22.0 or later. This recoding causes the Xenon

headlamp to be provided with the starting pulse (3) times.

A/C Evaporator - Ices Up

SUBJECT:

E46 Evaporator Ices-up During A/C Operation

150

MODEL:

E46, produced prior to November 1999

Situation:

The air output from the ventilation grills is reduced (or may even cease) after using the air conditioning for a considerable length of time. The setting

of the blower speed on the IHKA control panel remains unchanged, and the blower can still be heard running. After the air conditioning system or

engine has been turned off, a large amount of water condensate melts and drains from the vehicle.

The airflow is restored after the A/C system is turned off for at least 30 minutes.

Cause:

A faulty evaporator temperature sensor causes the evaporator to ice-up in air conditioning mode.

Correction:

On a customer complaint basis only, using DIS/MoDiC tester perform a functional check of the evaporator temperature sensor, and replace the

sensor if found defective.

Procedure:

1. Connect vehicle to DIS/MoDiC tester.

2. Select "Diagnostic Control Unit Function", and "IHKA Heater/Automatic A/C Control"

3. Select "A/C control system".

4. Select "Evaporator temperature"

5. Select "Display"

6. With the engine switched off, and at room temperature (approx. 68 (F) read the temperature value of the evaporator temperature sensor

(should be around 20 (C).

7. Then start the engine and switch the A/C system on. Set temperature on the IHKA control panel at 59 (F), and the blower to the lowest speed.

After approximately 3 to 4 minutes of A/C operation, the temperature of the evaporator sensor displayed in the DIS/MoDiC should drop to at

least 10(C).

8. If the values specified in step 7 are not achieved, the evaporator temperature sensor must be replaced. (If the test criteria are met, the

evaporator temperature sensor is not at fault, and further diagnosis should be performed, e.g.: micro-filter, A/C compressor clutch, etc.).

The evaporator temperature sensor is located above the driver's footwell, on the left lower part of the IHKA box.

Fog Lamps - Condensation in Lens

SUBJECT:

Condensation in Front Foglamps

MODEL:

E46 Coupe/Convertible (323Ci/Cic, 328Ci/Cic) Vehicles produced before June 2000

Situation:

One or both front foglamps have condensation on the inside of the lens which will not disappear after turning the headlights on briefly.

Cause:

The lower ventilation tube on the foglamp is kinked due to incorrect installation. As a result, there is inadequate ventilation of the front fog lamp.

Note that the kinked ventilation tube is only visible after the horizontal body colored trim piece below the foglamp has been removed.

366

Procedure:

In case of a customer complaint, remove the front foglamp and bulb (refer to Repair Instruction 63 17 000) and dry them out at a clean work place

by using a hot air blower.

Reinstall the front foglamp, taking care that the lower ventilation tube is correctly installed (not kinked). In addition, check that the upper

securing/ventilation grommet is tight.

It is not necessary to replace parts.
