1.2TSI - replacing filament bulb DRL with LED bulb

[mirko55]

Remember - I'm not talking about changing the fog light bulb; I'm wanting to change the DRL bulb. I'm not sure what bulb style is used by the fog light, but the DRL bulb is an 1156 (bayonet style) and looks like this:



Maybe that would account for my confusion as to how I could fit the bulb you suggested .

Hi scobb,

time ago I solve same problem. It is nothing CAN compatible and nothing else.
Only thing is you have (not only you but everybody ) changed polarity in your bulb base in
day lights.
There are 2 ways how to connect it:

1. Go to VW dealer and they change pins in base bulb connector, now you have - on a middle
and + on metal part of the bulb. because of plastic base nothing happen.

2. you have to disolder and open bulb you received from ebay and install there SMD rectifier
and after doesn't matter how you connect your bulb to polarity.

After you make one from these changes bulb will lit normally!!!!!

I found same strange polarity at my friend's Skoda Octavia II FL MY2010, I chosen 2nd possibility
and everything worked properly.
My friend with Skoda chosen 1st possibility and everything worked properly as well

Speak to t8ups,


Builds custom led replacements with Inbuilt resistors. Vags have issues with the inbuilt sensors which can cause a lot of issues

O and cheap to!

Guys,

it is not so problem with CAN compatibility but only with reversed polarity in bulb base...

Explanation: before I had Golf V and recognized there was different wrong bulb identification - in case I changed LED bulb instead of
original one, switch on an ignition - control unit made measurement and disconnect voltage from this bulb. Voltage been restored
after each switch - on ignition...
I measured it in new Polo and Skoda is different system - control unit test bulbs by different way - it try to adapt
on lower currents through LED and didn't switch off voltage from bulb.
I changed LED for daylight lights, sign lights ... and everything working properly without any indication and I used bulbs without
any built in resistor
