Front Turn Signal
1 - 20 of 28 Posts
I bet there is a setting somewhere in VCDS to tell it there is an LED bulb in there. I have that adapted in my GTI for LED tail/brake bulbs. It basically lets the car know not to expect a lot of current draw so it won't give a bulb out warning.
I had a quick look at the adaptation settings tonight - there are literally hundreds for all the different light drivers. I need to spend a couple of hours this weekend going through the VCDS mods that are available. Looks to be at least as complicated as the GTI.

I ordered a couple of LED bulbs which will probably need VCDS coding. I'm not a big fan of extra heat producing load resistors if you can just code it out. With the clear lenses it's hard because you need something with some forward firing LEDs, but most of them are hideous. I ordered these and I'll let you know how they work.

Sounds good, let me know how they turn out. Thanks!
The bulbs arrived. They look nice. Installed one on the left side, fits nice and securely in the bulb holder. Good start.
Turned on 4 way flashers, works fine. Pretty bright and of course the instant response.
Turned on the ignition, expecting a bulb out error, but no. And the turn signals work just fine. No coding needed!
There's a slight vertical dark line in the reflector compared to the original due to the design of the bulb, but really who is going to notice that?
I will take more photos when it gets darker of the beam patterns on the garage door to compare.
I also left the flashers on for about 10 minutes and checked how hot they got. The original, you could feel the warmth on the outside of the headlight lens. The LED maybe slightly. Took the bulbs out - the LED was hot enough that you couldn't just hold it between your fingers without saying "Ouch", but it wasn't nearly as hot as the incandescent.
I really ought to check how much current these draw too. I might get around to that later on as well.

That's better. I see no issues with visibility from any angle. The beam pattern seems to spread a lot more than the incandescent, probably because the LED elements are slightly further away from the socket than the filament is in the incandescent bulb. LED on the left, original incandescent on the right.
I think they get a thumbs up from me.

Wow, awesome write up and I am sold on these LED bulbs. Especially knowing the fact that no coding is needed just made it that much better. I’ve been in the LED business for over 25 years and seeing the improvements these LED products has come puts a smile on my face. Thanks again for sharing the result and I’ll be ordering these tonight for my car.
The bulbs themselves do not seem to care about polarity (unless I just got really lucky 6 times in a row!), but the insanely easy to get to and remove bulb holders need to go back in the same way up (twist 45 degrees counterclockwise viewed from the back of the headlight).
Thanks for the tip. Can’t wait to get the LED bulbs.

Swapped mine out. No need for resistors.

What’s the bulb number? I googled it but have different numbers.
I got them direct from SIRIUSLED.
