etaf Posted yesterday at 02:26 PM Share Posted yesterday at 02:26 PM Hi I have a A3 2014 reg , and the dipped beam buld intermittently goes - I got the warning about it - which was on all the time - BOTH the dipped and headlight do not work I popped into halfords to get a bulb change - which i have done on other cars - as its just as easy for them to put the correct bulb in BUT they say its a HID bulb and they cannot change as its a wheel arch removal on the way home , switched the lights on and it worked ok for about a mile and then went again purchased the bulb DS3 (they checked the reg) - £50+ looking at youtube videos , it does appear wheel off, arch out and then either an anticlockwise twist or some complicted spring assembly got a low level jack and axle stands , garage cant get to it for weeks , been waiting for the rain to stop long enough to start on the job , as i cannot get it into my garage and jacked up with enough room to work on. just a little concerned it may not be the bulb And i purchased 2 bulbs as i read something about colour changes etc , so i may get around to doing both sides Also supposed to be some high voltage on the bulb BUT my question , DO these bulbs go intermittent , I assume a problem with the ballast thing on the back of the bulb - hope so , and should you change in pairs thanks Quote Link to comment Share on other sites More sharing options...
