    True, but the great advantage of the Autocheck is that you can never forget and also the bulbs are checked every few minutes whilst you are driving. Could prevent an on-the-spot fine from the Austrian police!

    Just so i'm clear on it, when you say DRL do you mean when the side lights are on?

    Not exactly...the fronts are on (I assume they are the side lights) but not the rears...on the S3 can be switched either on or off, and in the on position just come on with the engine.

    No, DRLs are not side or parking lights as they are better described. DRLs are, at the moment, only on A3s fitted with Bi-Xenon headlights. The outer units in the headlights are xenon units providing both dip and main beam. The inner units have a longlife 21w bulb (similar to a brake light bulb) and are designed to be on during daylight whenever the car is moving. Hence the name Daytime Running Lights. Research has shown that the DRLs do make a car more visable to both other road users and pedestrians and thus reduce accidents. When the DRLs are on it is only the two front units that are on, the rear lights remain off. The DRLs turn off automatically when the headlights are turned on. Audi use longlife bulbs in the DRLs because they will be most of the time.

    Their use is currently recommended in some EU countries like France, Germany and Holland and mandatory in all Scandanavian counties and Austria. It is intended that they will be mandatory across the whole of the EU, including the UK, by 2010.

    Depends if you have Xenons or Bi-Xenons. How old is your car? If you have ordinary Xenons then the inner light unit has a halogen bulb to provide the main beam and a xenon unit in the outer unit to provide the dip beam.

    If you have Bi-Xenon, then the outer unit provides both dim and main and the inner unit is a DRL.

    Also applies to Xenon Plus units.

    What's the difference between Xenon Plus and Bi-Xenon. Does anyone know when the Audi changed from Xenon to Xenon Plus to Bi-Xenon.

    I'll have a look at my copy of ETKA to see if it gives any clues.

    Having now looked at some past price lists for the A3 range and the ETKA parts catalogue it appears that there are just two types of Xenon headlights used on the A3.

    Xenon is listed in the price lists up to 2005. From the January 2006 list the description changes to Xenon Plus and stays with that description up to and including the latest April 2007 price list. My own Sportback ordered from the November 2006 price list therefore has Xenon Plus headlights.

    The parts catalogue only lists Xenon and Bi-Xenon. So I can only assume that Xenon Plus is the marketing name for what the parts catalogue refers to as Bi-Xenon.

    Basically the Xenons have a xenon dip beam unit and a halogen H7 bulb for the main beam unit. The Xenon Plus or Bi-Xenon has a xenon unit that provides both dip and main beams with the other unit being a DRL.

    So emzino it seems that your 2003 A3 will have Xenon and not Xenon Plus or Bi-Xenon and will not therefore have DRLs.

    Xenon plus is Audis marketing term for Bi-xenon lights.

    Dave,

    Have you heard the noise the headlamps make when you flash the main beam? Sounds like a heavy shutter is moving about in there, unless it's the relays under the dash that I can hear.

    Regards, John.

    P.S. Thanks again for all your recent assistance. :arco:

    Very interesting, there's a good how to guide featuring an RS4.

    http://webpages.charter.net/parkhill/RS4/DIY/DRL&CLBulbChange.pdf

    Here's some pics with the super blue bulbs mentioned in the article -
    DRL on. (standard DRL bulbs on the left)

    Xenon on. (standard DRL bulbs on the left)

    Easy to see why people want to change them!

    No worries.. :icon_thumright:

    Yet more food for thought.. although IIRC they didn't recommend those particular bulbs as they caused the cases to melt :( .

    Phillips do something similar which is more reliable apparently.

    But which DRL's did he go for in the end? There is a strike-through in the text at the start of the article, due to over-heating issues, but then no mention of an alternative - unless I overlooked it (its late)

    Those 35W Halogens didn't make any difference! What a shame =/

    LEDs run much much much cooler than a bulb. I can't see them melting. Looks great! :icon_thumright:

    Mitch,

    I saw your vag-com post on the DRL intensity setting. Did you try to adjust the setting with the 35w halogens to see if it made a difference?

    Regards, John.

    It may be possible to use LEDs with a ballast resistor connected, to fool DIS into thinking it's the same as a filament bulb. I have looked into this because I wanted some red LEDs for the rear lights, but while resistors are cheap, it would require a bit of soldering and general messing around (i.e. finding the correct resistance) to get it to work.

    I'm still confused to whether I have DRLs or not lol.

    It basically goes like this for me:

    (Xenons)(MainBeam(Little bulb in the corner))===Grill===((Little bulb in the corner)MainBeam)(Xenons)

    I've got a 53 plated A3. Will those PIAA bulbs work for me?

    from what you describe I would say No you do not have DRLs.

    To have DRLs you have to have Bi-Xenon headlights which provide both the main and dip beams in the same Xenon unit. Yours has the main beam provided by a seperate halogen main beam unit. With a Bi-Xenon headlight there is no spererate halogen main beam bulb and the 21w DRL bulb is located where your halogen main beam bulb is located.

    On my car the lights are, from left to right...

    Bi-Xenon (main and dip) - DRL (with small parking/side light bulb as well) - Grill - DRL - Bi-Xenon.

    Hope this helps!

    In connection with the 21w replacement bulbs that some of you have fitted it will be interesting to know how long these bulbs last. This is not usually an issue because most bulbs are only on at night or in bad weather but the bulb in a DRL is on all the time you are driving. The standard factory fitted bulbs are described as 'long-life' bulbs and should last a lot longer than standard bulbs.

    Can the same not be said for bulbs that you use all night then. DRL's are off when its dark or raining as you would have the main lights on, therfore equalling the time they are running!

    I only use the DRL's when it is dull, overcast etc (all the time at present then) and tend to have them off when its sunny as you look like a tit with them on.

    Personally my car gets driven a lot more during the day than it does at night.

    Each to his own, but the whole point of Daytime Running Lights is just that. They are not required yet in the UK but in counties where the are, they are required to be ON at all times, hence their name. I have mine swiched on all the time.

    Last night after finally getting mine back from the stealers i changed the bulds I had ordered in the DRL's. Sorry no after pictures of them both but you can get the idea from the shots.

    Great colour and no more "yellow" DRL's :yahoo:

    Take it the ordinary DRL bulb is on the left and the new one on the right?

    If so do you have a link for the replacement ones you have that get rid of the yellow look please as I wouldn't mind some.
