    Trim : Sri

    Engine : 2.2 Direct

    Year : 2007

    Default HIDs and auto-lights

    Right, I have decided to upgrade from 1x candlepower per headlight to HIDs. Can anyone tell me if there will be a problem with the auto-lights function I have fitted? At the moment the dipped beam comes on the instant I start up, but if HIDs take a longer time (however short) to get going will they be damaged at all by the instant switch on?
    Car is a facelift and the ECU has been changed to Xenons 'present' if that makes any difference. Ta.

    The only issue you might have in winter with the HIDs coming on with the light switch in auto mode is that they might not fire up if the battery voltage is slightly low and pulled down even more when cranking the engine. If that does happen, just switch the headlight switch off and back on again once the engine is running.

    I tend not to leave mine in auto mode anyway. Found it too dangerous on the way to work as there is an avenue of trees and my lights come on just as I exit the trees and then turn themselves back off again. Just so happens there is a T junction not far up the road from there and people think I've flashed them out. Eeeek!

    Yes, programming the UEC to put it in xenon mode will help anyway, at it will prevent the OBD to check for H7 bulbs and also turn off PWM dimming pulse voltage, helping the bulbs' health, and avoiding errors to show up.

    You should definitely do it when fitting HID. Original xenon bulbs are HID too, BTW : the term doesn't only apply to tuning aftermarket parts.

    AFL is rather related to additonal external modules.

    Here you just need to inform the UEC about how to properly power and check the bulbs.

    The UEC is the "underhood Electric Centre", so it's actually just the fusebox by the battery side : there's an electronic module in the bottom.

    You'll have to program a variant in it using the garage's Tech2 or a Vaux-Com.

    Some of the possibilities are described here :

    Xenon Headlamps - Not Present / Present
    I couldn't find any allusion to "xenon" in the different models descriptions, so the option should luckily be available to yours, whatever the series...

    yeah all have a look, what about these daytime running lights ive tryed them all- 1 is the side lights on, but they dont go dim or anything which would be handy, 2 i think is just low and a think 3 is both not quite sure about that cant remember, and 4 nothing happened must be a different circut. would be good to have the dimming function.

    What dim function are talking about, and what would you want them to do ?

    I'm personally intending to use the angel eyes rings as DRLs, but I wouldn't want the tail lights nor number plate to light up (I think it's still possible if I don't activate DRLs in the REC, but only in the UEC), and maybe dim the front sidelights in real (night) sidelights mode, but the most important feature I'd like is NOT having the instrument panel nor board computer going to night lighting mode...

    Do you think there's an available mode for that ? Else I'll use external electronics... Which we can discuss if you want.

    4 activated my front fogs as DRL's on my preface 2004 3.2 Gsi (half can).

    I should add that they are in reduced light mode, go off when sidelights/main beam are selected (or when engine switched off), and go to full power when used as normal via the fog lamp switch.

    I had time to try some options this morning, as I had to check if my Op-Com update was working.

    Pre-facelift too, OEM xenon and fog lights :

    Mode 1 and 4 do nothing ;

    Mode 2 and 3 light the xenon low beams when the engine is running.

    What is mode 1 supposed to do ? I'd like to have the sidelights on...

    None of them did light the instruments panel, which is OK for me.
