1.2TSI - replacing filament bulb DRL with LED bulb

[gavs]

@gavs: very wise to ask simple questions, as I am reasonably new to this field. I'll try and explain:

1. My standard NZ-spec car has a light assembly below the front bumper, per my photo, that comprises 2 bulbs within the one assembly. The inboard bulb (nearest the radiator) is a fog light; the outboard bulb (nearest the wheels) is the DRL, currently populated with a bog-standard filament bulb (21W from memory). With the ignition on, the DRLs are illuminated. When the sidelights or headlights are illuminated, the DRLs are extinguished.

2. The LED bulbs I bought don't mention being CANBUS compatible, so I suppose the problem may be as simple as that. From what I've read on the briskoda forum I use regularly, CANBUS is not as fully implemented in the Polo 6r as it is for some VAG cars, hence I have been able to swap the number plate lights on my Polo for LEDs without any recoding or dashboard error (unlike my Skoda, which does throw an error). I would have thought that non-CANBUS bulbs would at worst throw a dashboard error, but instead they just don't light up, no warnings, no errors, no light .

Given the existing functioning lights are coded to work already, surely there wouldn't need to be any coding adjustment, would there?

I think you inadventantly answered your own question. The 6R has 2 fundamental systems with many varients of them but we will just narrow it to 2 for arguments sake. There is GTi canbus and regular 6R canbus, the 6R is much more integrated whereas the regular 6R system is not. If you are not getting bulb-light errors on the dash, this does not mean that the light isn't throwing an error. I would start by getting your hands on some properley specced LED bulbs from somewhere like hids4u.co.uk and see if these work for you.

Ahhh ok. My Polo does not have this in the fog light part so that's where I was getting confused.
Sorry buddy I can't help ya then. However if the connection is similar to the one posted above then I can't see why It wouldn't work?

[scobb]

Thanks, good idea. I had no idea that the same bulb shape/style could go by so many different names! Any idea what I should be looking for at hids4u.co.uk? I can see bulbs listed on their site by the names of 380, 382, 581 and 241, all of which look potentially suitable.

You could just get these and solve all your problems...lol

When you get them Bassik post a photo up

I ain't getting these. It's to expensive and I'd prefer to see them on someone elses car first.

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

[bootheman]

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
