My parking lamps will not turn off when i turn off the engine. 2008 750li

tell good and bad, not just bad things.!
car starts and runs and drives ok? day time?
dash dimmer turned down, kids played with dads car?
well tail lamps dead (really are up to 10 or more parking lamps dead, is blow fuse or BCM failures.
why not scan the PCM see DTC errors first. save tons of work , if DTCs are there.
cars have 2 or more fuse boxes. cab and bay(engine)
did you check them all?
if car drives, I will say why parks fails. front and rear and sides of cars. are park lamps as are license plate lamps.
the BCM body brain on this car is SJB smart junction box.
SJB Fuse F2 and F3 good
and the HL switch not bad, and park switch there good
the SJB has CPU brain and a park relay
if the CPU sees park turned on it closes the park relay in SJB
there 8 park lamps.all 8 lamps run off fuse F3
so if one lamp works, then F3 is good if all 8 are dead F3 is blown
or the relay is bad.

these words assumes car runs. (engine runs)
and the battery is not dead
nor battery at 10vdc or less.
I check all that and all is covered in the service manual I just read.
for you.

Park, Tail and Marker Lamps
The park, tail and marker lamps, including the license lamps, are turned on when the headlamp switch is placed in the PARK or ON position or anytime the headlights are requested. The PARK LPS 30 A fuse in the engine wiring harness junction block supplies battery positive voltage to both the park lamp relay switch contacts and the park lamp coil circuit. The body control module (BCM) provides a ground or control circuit to the park lamp relay coil circuit. When the park lamps are turned on the BCM energizes the park lamp relay. Current flow is from the park lamp relay to the FR PRK 10 A fuse, RR PRK 10 A fuse, LR PRK 10 A fuse, and the TRL PRK 15 A fuse, and to their respective park and marker lamps. The front park and marker lamps are grounded at G100. The rear park and marker lamps are grounded at G401. The license lamps are grounded at G401. If the headlight switch is left in the ON position, the inadvertent power control feature will turn off the park, tail and marker lamps approximately 10 minutes after the ignition switch is turned to the OFF position. If the driver places the headlight switch in the ON position after the ignition switch has been turned OFF, or if the ignition switch is in the ACCY position, the park, tail and marker lamps will remain on until turned off or the battery runs dead.
The CTSY LMP 15 A fuse in the engine wiring harness junction block supplies battery positive voltage to both the inadvertent power relay switch contacts and the inadvertent power relay coil circuit. The body control module (BCM) provides a ground or control circuit to the park lamp relay coil circuit. When the driver presses the cargo lamp switch, the BCM energizes the inadvertent power relay. Current flow is from the inadvertent power relay to the cargo lamps. The cargo lamps are grounded at G203.

What about them ? What front lights ? Headlamps , park lamps, marker lamps ? They don't work ?

Exterior Lamps
The exterior lighting system consist of the following lamps:
• The Headlamps
• The Daytime Running Lamps (DRL)
• The Clearance Lamps (Y92 roof rack only)
• The Cornering Lamps
• The Front Fog Lamps
• The Rear Fog Lamps (Export)
• The Park, Tail and Marker Lamps

• The Backup Lamps

Park, Tail, Marker, License, and Clearance Lamps
The park, tail, marker, license, and clearance (Y92 only) lamps are turned on when the headlamp switch is placed in the PARK or ON position or anytime the headlights are requested. The I/P BATT fuse in the engine wiring harness junction block supplies battery positive voltage to both the park lamp relay switch contacts and the park lamp coil circuit. The body control module (BCM) provides a ground or control circuit to the park lamp relay coil circuit. When the park lamps are turned on, the BCM energizes the park lamp relay. Current flow is from the park lamp relay to the individual park lamp circuit fuses and to their respective park, tail, marker, and license lamps. The front park and marker lamps are grounded at G107 and G103. The tail lamps are grounded at G401 and G402. The license lamps are grounded at G401. When equipped with the Y92 roof rack option, the clearance lamps are grounded at G302. If the driver places the headlight switch in the ON position after the ignition switch has been turned OFF, the park, tail, marker, license, and clearance lamps will remain on until turned off or the battery runs dead.
The T PARK fuse in the rear fuse-relay block supplies battery positive voltage to a separate park lamp circuit connected to the trailer wiring harness.

Electric Testing Techniques You Need to Know

This is how a professional tech would go about diagnosing this problem .

The park, tail, license, and marker lamps are turned ON when the headlamp switch is placed in either the HEAD or PARK lamp positions, or anytime the automatic light control (ALC) turns the headlamps ON. When the headlamp switch is placed in the park lamp or headlamp positions, ground from G304 is applied through the signal circuit to the BCM indicating the park lamp request. In response to this signal, the BCM applies ground through the park lamp relay control circuit energizing the PARK LP PCB Relay. With the relay energized, battery voltage is applied through the switch side of the relay, both park lamp fuses, and the supply voltage circuits illuminating the park, tail, marker, and license lamps.

is car battery fully charged, and at >=12.6vdc rested?>
is this uSA car, or in a country with manitory, DRL lamps
Daylightrunninglamps......??????????
parks, they are, the tail lights on all modern cars are park.
after all the front park lamps cant be called, tail lights.
so begs the question are all 20 park lamps out.
front, sides read, and inside cab. those too are park
dash dimmer lamps run off of PARK feed.
The MK jeep, ill log in to mitchells for you. and read that page.
my guess is the BCM or TIPM modules run this feed.
year tells me that.
but first the 2 questions, due to me not there .
1: car drives and runs perfectly ? day and night?
2: no other electrrics dead>?....??? all , of them......

a: check fuses, all fuses? or just some.
b: did you scan the PCM yet, it will tell you whats up. on this car.
not scanning modern cars is a hopeless path... for sure.

the parks lamps on , are sent via car networks.
unlike cars of old with simple switch and copper wires.
3 computers in the chain,,,,,
scan it you must,

here is the page in the the FSM covering PARKS.
quote:
The park lamps system includes the left (lighting) multi-function switch, the SCM, the EMIC and the TIPM. The front park/turn lamp and the position lamp bulbs each have a path to ground at all times through their connection to the engine compartment wire harness. The engine compartment wire harness has takeouts with eyelet terminals that are secured by nuts to ground studs on the front end sheet metal within the engine compartment. The rear lamp units and license plate lamp bulbs have a path to ground at all times through a takeout and eyelet terminal of the unibody wire harness that is secured by a nut to a ground stud on the body sheet metal within the passenger compartment.
The SCM monitors a hard wired multiplex input from the left multi-function switch, then sends the appropriate electronic headlamp switch status messages to the EMIC over the LIN data bus. Then the EMIC relays the appropriate electronic message to the TIPM over the CAN data bus. The TIPM responds to these messages by providing a battery voltage output to the appropriate lamp bulbs through high side drivers on the proper park/tail/license/running lamp right and left circuits. The TIPM and the SCM also send the appropriate electronic messages to the EMIC to control the illumination and lighting level of the panel lamps.
The TIPM provides a battery saver (load shedding) feature for the park lamps, which will turn these lamps OFF if they are left ON for more than about eight minutes with the ignition switch in the LOCK position. The SCM and the EMIC each provide a fail-safe feature for the park lamps, which will send an electronic message to the TIPM to turn these lamps ON automatically if there is no input available from the left multi-function switch. The TIPM also provides a fail-safe feature for the park lamps that will turn these lamps ON automatically whenever a loss of CAN bus communication is detected with the ignition switch in the ON position.

The park, tail, marker and license lamps are turned on when the headlamp switch is placed in the PARK or ON position or anytime the headlights are requested. The PK LPS fuse in the IP fuse block supplies battery positive voltage to the park lamp relay and the headlamp switch. The body control module (BCM) provides a ground, or control circuit, to the park lamp relay coil circuit during ALC operation. When the park lamps are turned on during ALC, the BCM energizes the park lamp relay. The park lamps can also be supplied battery positive voltage directly from the headlamp switch. Current flow is to the park, tail, marker and license lamps. The front park and marker lamps are grounded at G100 and G101. The rear park, tail, marker and license lamps are grounded at G400 and G401. If the headlight switch is left in the ON position, the park, tail and marker lamps will remain on until turned off or the battery runs dead.
Check the headlamp switch !

Without testing i would say you have DRL control module problem , But that would just be a guess .
In the night mode, the DRL ambient light sensor senses darkness. Then, the DRL module turns off the front turn lamps and turns on the headlamps through circuit 10. The DRL module also turns on the park, side marker, license, and tail lamps. If the engine should stall with the DRL control module in the night mode, the DRL control module will turn off the headlamps and leave the side marker, park, license and tail lamps on while the engine is being cranked. The headlamp switch operates as usual.
The Daytime Running Lamps (DRL) control module is designed to automatically operate exterior lights depending on outside light conditions. The DRL control module operates in two modes, the day mode and the night mode. In the day mode, the DRL ambient light sensor senses daylight. Then, the DRL control module turns on the front turn lamps (non-flashing) if under the following conditions:
• The ignition switch is on.
• The headlamps switch is in the OFF position.
• The park brake is released.

The brightness of the Vacuum Fluorescent (VF) displays is controlled by two signals: the park lamps on signal (circuit 230) and the VF dimming signal (circuit 308). With the park lamps on, the VF display of the radio, heater, A/C control (with RPO CJ2) and the instrument cluster will dim for nighttime viewing. When the park lamps on signal is not present (park lamps off), the VF displays are at high brightness for daytime viewing. When the park lamps are on, the I/P lamp dimmer switch provides a signal (VF Dimming Signal circuit 308) which controls the brightness of the VF displays when the I/P lamp dimmer switch is adjusted.

Do the Daytime running light's work ?
