Footwell Lighting

Agree with Adam but perhaps return the lights (LEDs) to normal first so there's no dispute with the dealer. I know I know but .... sometimes it makes life easier.

I've heard the strange beeps that you talked about coming through the speakers, but that was when my battery was flat...

Cars of today do very weird things when the battery start going flat. Get your battery checked asap. I've had cars come up with weird faults when the battery was going flat.

I've heard the strange beeps that you talked about coming through the speakers, but that was when my battery was flat...

The beeps (usually random) are a the Battery Load management controller telling the Central Electrics Controller - 09 to shed electrical loads to preserve the battery charge. Intended for cars when in transportation to warn a battery is low.

The tones start at about 11.75 volts in the 09 controller, I use the Engine Controller measuring blocks to read the "system" voltage which is about 0.50 volts lower than across the battery terminals.

In VCDS it will first appear here at the top of an Auto-Scan.....
This is the first hint of a low voltage, usually just before the tones start.

Chassis Type: 1K0
Scan: 01 02 03 08 09 14 15 16 17 19 25 2E 42 44 46 52 56

VIN: WVWZZZ

01-Engine -- Status: OK 0000
02-Auto Trans -- Status: OK 0000
03-ABS Brakes -- Status: OK 0000
04-Steering Angle -- Status: OK 0000
08-Auto HVAC -- Status: OK 0000
09-Cent. Elect. -- Status: Malfunction 0010
14-Susp. Elect. -- Status: OK 0000
15-Airbags -- Status: OK 0000
16-Steering wheel -- Status: OK 0000
17-Instruments -- Status: OK 0000
19-CAN Gateway -- Status: OK 0000
25-Immobilizer -- Status: OK 0000
2E-Media Player 3 -- Status: OK 0000
42-Door Elect, Driver -- Status: OK 0000
44-Steering Assist -- Status: OK 0000
46-Central Conv. -- Status: OK 0000
52-Door Elect, Pass. -- Status: OK 0000

Then as the volts get lower, fault code 00907 appears (self clearing if the engine is run).

1 Fault Found:
00907 - Intervention load Management
000 - -
Freeze Frame:
Fault Status: 01100000
Fault Priority: 6
Fault Frequency: 1
Reset counter: 227
Mileage: 16041 km
Time Indication: 0

Time: 18:04:07

Freeze Frame:

Bottom line is the battery voltage is low after what you have been doing.

Engine just needs to be run as normal to re-charge the battery. As said the fault code will self clear if its in the 09 controller fault memory.

Thank you mate, this all makes sense now. I have replaced the led bulbs in the footwell and the trunk with stock ones and the problem has gone. The trunk led light was causing some crazy electric issues. When i would lock the car the rear window on off button on the drivers door would either flash (dead locks on) or stay on (dead locks off) This would have been causing drain on the battery thus when i come to my car in a morning the leaving home lights would not work and the low voltage tone from the speakers nwould sound.

Next question is can the car be reprogramed so that these trunk led lights dont cause any issues? They are brighter and better than stock.

Hey Guys,
Looking at getting some red leds for the foot well lights in my GTI. Wondering if anyone can tell me what size the standard bulbs are? Or any possibly leds that will fit?

Cheers
Simon

T10. Any LEDs will do. Don't need to error free ones. Although stay away from the tall ones, as they won't fit in the holder.

Awesome thanks heaps!
