    Common issues with this fault description on various cars, ballast, bulb & even headlight switch, only way to determine tbh mate is to swap bits around or could cost a few pennies to change all.

    One of my lights began flickering randomly yesterday but went away afterwards. Thinking of replacing both for some 6000k ones. Anybody know the bulb type for the OEM bi-xenons and also how difficult are they to change without removing the front bumper? Do the headlights come out without taking the bumper of or do you just make space behind the unit (i.e. dismount PAS fluid resevoir etc.)?

    Thanks in advance, Az.

    x2

    mine had been flickering for nearly a year - finally gave in and bought 2 x OSRAM 66144 XENARC D1S 35W HID XENON REPLACEMENT BULBS for £90 delivered from HIDS Direct Ltd.. and hey presto, all fixed

    On mine it was the bulb, changed them for some unkown make off ebay for £38 for 5300K (same as OEM) and been fine since, (that was 12K miles ago). Also headlight can be removed without bumper removal but you will need a very long T20 to remove the bottom screw.

    Will be the bulb happened to me. You will not get warning light out.

    Just buy a pair and fit both of them at least you know you have changed 2. I got 2x 4300k OEM on ebay for £80

    Do the headlights need to be removed in order to change the bulbs or can they be replaced as they are (moving the PAS fluid reservoir etc.)?

    my local VAG indy managed to do it without removing the bumper, however it cost me 45 mins labour - but well worth it!
