Hi mate, I'm pretty sure this boils down to the correct coding in VCDS. I've just had HIDS (in Depo projectors) fitted, so made sure I sorted this myself.
You need to check the "Bi xenons without shutters" box in VCDS. If you're not sure what that means, find someone with VCDS (a mate or an auto electrician) and show them this post.
I assume the HIDs are going in a proper projector headlight rather than the standard reflector units that should house halogens? It's a little bit frowned-upon to put HIDs in anything other than projectors - it can be a bit glarey for oncoming traffic otherwise.
Hi mate, n00b response here, but whats is VCDS?? Only had my gti a matter of weeks so this is all new to me.
Ive had HIDS in all my cars in the past (106's, glanza's etc..) so never had to worry about any errors on the dash as such...
In regards to headlight fitment i was just planning on fitting them to my standard headlights that are on the car now? Would that not work?
Cheers for the response
VCDS is the proper VW diagnostics and coding software, loaded onto a laptop. A lead goes between the car and the laptop, letting you find fault codes, log data, and in this case set the car up correctly for certain hardware.
However, I do not recommend putting a HID kit into standard headlights. HIDs are supposed to be used in projectors. If they're used in normal reflectors it's almost impossible to ensure the light doesn't scatter and blind oncoming drivers.
I strongly suggest having a rethink. If you can't/won't fit a pair of projector headlights but still want better light output from your standard headlights, try some Osram Nightbreaker halogen bulbs, or similar. But please don't put HIDs in them.
