Cayenne 04 TT interior lights

[mbagge01]

I have been replacing my interior lights with LED's and notice that my middle light in the front over head lights (the cluster of three next to the homelink buttons) that is suppose to go on when the doors open does not work (with either the standard or LED bulb). The lights next to it which you can turn on for the passenger or driver work fine but that middle light in that 3 light cluster in the front overhead does not seem to work. Is there a fuse that could have blown specific to this light. I would appreciate anyones advice and help.

Will it operate with the switch? I have seen the switch melt which causes the contacts to not engage. You need to buy the complete light assembly as the switch is not available as a separate piece.

I have changed almost all bulbs to white led inside. Looks nice, more updated and not (as I feared) tacky.. However am experiencing odd behavior as well with the center light console becoming in-operational after the ligts turn themselves off if doors remain open too long..The only way I found to get the light back is to close car (like you were going home) and re-open..

Can it be so that the LEDs disrupts the function somehow?

LED bulbs, compared to stock, even if the exact same form-factor/size will disrupt overall electric function simply based on their differing load (less) requirements compared to stock incandescent. Often the case is you can replace a few bulbs with no consequences but one you get to a certain number of bulbs some electrical issues surface. If your switch is OK, and not damaged, try putting stock bulbs back everywhere you replaced them and then try LEDs only in the center console (after you put stock bulbs back in the center to confirm the console is not damaged). I remember reading about the requirement for LED bulb power adaptors when upgrading -- much like putting HID headlights in non HID vehicles requires more then a basic bulb/housing swap.

Let us know when you sort it out and post some pics -- it must be a very sleek look.

The LED bulbs draw milliamps - the incandescents draw amps. (1000:1 ratios..) They should only cause a problem IF the bulb has a monitoring circuit that measures currenf flow through the incandescent and triggers when it measures less current then it should. The only other problem might be if an LED bulb is put in the wrong way, it may present a short-circuit to the monitor or switch, drawing too much current and shutting down the circuit. More then one person has killed off an entire lighting circuit putting the LED in backwards in the BMW world.

Lights will go out after a lengthy period of time with the a door open. This is a normal power saving function.
