Hey everyone,

It's my first post around here and I'm looking for some expertise.
I recently bought a .1 c2s and realized the center console where the controls for sport, s+, pse and so on is lacking backlighting for all except two buttons - full open roof and the raise the back.
Decided to open the module and see what's up and this is how it looks like as I opened it and after some cleaning. There are traces of some spillage and definitely a short on the button that closes the roof.

I am going to try have this circuit board repaired and am looking to understand if someone has done this before.
Especially interested in knowing the specifications for the Leds and if any other component would need changing.

Thanks everyone

After cleaning, clear that the only two buttons without any \"spillage" are the two middle ones that are working.


Need the specification of this led

 

I think most Porsche owners on this forum are better versed in mechanical repairs, as opposed to electrical repairs, especially circuit boards. I think the only real option is to buy a new one from Porsche, but I don’t really know.

 

Super unlikely that any LEDs are actually bad. More likely, some low-resistance paths have formed that are keeping them from being turned on. Possibly/likely these paths are some distance away from the affected LEDs. Depending on what was spilled, I'd clean the board thoroughly with 99% isopropyl alcohol or deionized water, let it dry completely, and then try reinstalling it.

If that doesn't work, you will probably need to order a new board.

 

I get that, I'm just trying to save myself a huge bill by asking porsche to order, program and install a new module. As it's difficult to get worse than it already is I'll go ahead and try it. Hopefully this can serve for someone in the future that has the same issue.

 

So I did clean the whole board and some spots seemed to have shorted. I reassembled everything but it just works as before. I'll have a friend that does this for a living take a look and repair it, hence why I wanted to know Led specifications to order them and have him replace them as well.
Thanks for the input!

 

Sorry, I don't know the LED part number.
My car is in storage, so I can't check, but are the buttons even back lit? Or does the led only light the "on" indicator?

If you can't repair the board, have you looked at eBay for a used replacement?
I see consoles from $150-$300. You'd probably have to look for your specific part number and button configuration but it might be worth a shot.

 

LEDs or in your case Surface Mounted Diode or light (LED) “SMD” are measured in millimeters (mm). You will need to select the color that best matches the existing light brightness or lumens on the circuitboard. The lumens range from warm to cool. The size of the SMD can be measured with a digital caliper in the mm setting (measure length x width). This will determine the size of the SMD. A quick check to determine if the SMD is blown is by using DMM or Digital Multimeter. Select the diode mode and place the red lead to the anode (+) on the SMD, and black lead (-) on the cathode. This should light up the SMD. If you don’t know the anode from cathode on the SMD, just reverse the leads. Good luck.
