Audi TT HID bulb needs replacing

Question edited for clarity

Not easy as it is HID. It is not normally the bulb, but the transformer unit. Details in the link.

Yes, it CAN be done without pulling the bumper, fender and entire headlight assembly.

I just completed a HID bulb replacement on my 02 SC430. Took about two hours and included a copious amount of swearing. It is a PITB process that is largely done by braille. Sausage fingered individuals should not even try. The clearance is very small - just enough to get your hand into position.

if you google search agains "sc430 headlight service manual" you will find a pdf of the headlight service procedure. I largely followed those instructions, but I have a few hints...

1. Do the passenger side first. Removing the air cleaner gives you some ability to see what you are doing. That lets you learn the process before you go do the driver side "blind".

2. The service manual did not mention a few wires that are present. The leads for the amber indicator light stretches tight across the HID moisture cap. You need to pull the amber indicator bulb assembly first. Fortunately, that is a simple twist and pull. Once the amber lamp was free, I disconnected its harness and set the bulb aside in a safe location.

2b. A pair of wires were physically attached to the HID cover. These make it extremely difficult to maneuver the cover, particularly when putting the cover back on. I ended up physically detaching those wires from the cover permanently. Made life a lot easier and will make replacing the HID bulbs simpler next time.

3. The HID bulb socket easily detaches. The wire spring bale is hinged and won't fly away when you get the two ends free. Those are freed with a squeeze and pull movement. You can do one side at a time.

4. Make certain the spring bale is swung out so it does not impeded placement of the new HID bulb.

5. Because you are doing most of the bulb insertion blind, it is difficult to avoid touching the quartz jacket to something. Practice with the old bulb first. Once in place, you gently rotate the bulb until its notches allow it to seat. You can feel that pretty easily.

I used the "MAXLUX HID Xenon Bulb D2C (D2S/D2R) 5000K" bulbs obtained via amazon. Yes, that price is indeed for a PAIR of bulbs. I thought it was for a single bulb due to the low price and ended up with four bulbs.

The new bulbs light up much brighter than my aging 02 HID bulbs. A slight bluer than the OEM Lexus bulbs, roughly the same color as the HID's on the Aston. Longevity is, of course, yet to be evaluated.

Success. It can be done, but I guarantee a lot of colorful language during the process.

To wire up an HID kit on the low beams of your Mazda 3 2005, you will need 3-4 things:
1- HID kit (bulbs and ballasts)
2- HID relay (connects your hid kit to your battery)
3- 4700uF capacitor (solves DRL flickering issue)
4- H7 hid bulb adaptor (you can also use the rubber piece that holds the bulb wires as a spacer)


Wiring diagram:

Tips on How to wire up:
1. HID bulb's amp wires connects with the ballast's amp wires. (There's only one way to connect them.)
2. The positive and the negative spade connectors from the hid relay connect with your vehicle's low beam connector, closest to your battery: the driver side. The passenger side low beam connector is not used and should be insulated. You can use electric tape.)
3. Each ballast is connected to one of the relay's clip connector, and it's grounded on each side to your vehicle's body. (One connector for each ballast, one for each side. You can use the screw for the body as a ground.)
4. The red wire(with the inline fuse) in the relay connects to your battery's positive terminal.
5. The capacitor sits on the relay switch. (Google for how to wire the capacitor onto the hid relay switch.) dynoxg image
6. The halogen bulb sits on an adapter. You can safely remove them from each other, and use an H7 hid adapter instead.

I have a 2005 Lexus Rx330 with HID AFS headlight. My passenger side light went out. I thought the bulb burnt out, so I bought a new bulb. After replacing the new bulb, it happened exactly like my old bulb. It light up lightly and then total black out. What's wrong with it? I thought the ballast burnt. I called Lexus dealer and asked for the new ballast/transformer. Surprised me, they don't know what is it. They told me they only know the wiring harness and the socket, but not the ballast ??????? Could you tell me what do I need to replace?

Thanks,

The ECU on my 2004 Sienna passenger HID light went bad due to the condensation in the light, or at least that's what it looked like when I opened it up. The ballast was all corroded. Anyway, I searched and searched online for a way to fix it without paying the dealer $900. I just fixed it today for $92. I got the replacement ballast brand new for $92 shipped from The Retrofit Source at this site: http://www.theretrofitsource.com/product_info.php?cPath=26&products_id=161
Then I searched for an online manual for 2004 Sienna, found that, and went through the procedure of partially removing the bumper cover, taking the screws for the light fixture out, turning it on it's side and replacing the ballast. It took me about 2 hours to do the whole job, and everything works fine.
By the way, I got the part from The Retrofit Source in about 2-3 days without paying any expedited shipping. They were extremely helpful on the phone, delivered earlier than I expected, and saved me $800!!

Did exactly as you said, replaced both bulbs with the d2s as you said and got them on ebay, driver side was clearly more difficult to put in, passenger side very easy, worked perfect for 1 day and the intermittent problem returned. What to do.

I'm having the same problem wiht my 2004 TT. Luck for me, the problem followed the bulb. I can't answer the question about the ignitor, though replacing it seems to be your fix. The ignitor ain't cheap, but the cheapest place I've found is www.1stvwparts.com. Good luck.

The ignitor or ballast must stay energized for the bulb to stay lit..If the bulb comes on then goes off, or flickers, then the ignitor is defective. You are in the early stages of failure, it will eventually stop working altogether

Changing the computer doesn't sound right. Most likely a bad oil temp sensor. Make sure you are using the recommended weight (synthetic) oil.

HEY WHATS UP BRO this is what you have to do i just got brand new headlight replacements for my 05 nissan altima and it looks great by the way if you replace one you should just do both becasue it will look weird. anyways i have an hid kit as well but so. what you have to do is remove the bumper take all the plastic screw things off the top and on the botton underneith the bumber then you remove 2 screws on each side of the bumper they are located kinda in the dender well then you unscrew those then you can pretty much pull the bumper off there are 4 screws holding on each headlight 2 on top one on the side and one on the bottom front in order to remove the headlight you have to take off the bumper. hope this helps oh ya and buy buy the way you should get an hid kit the bulbe size for the altima is an h1 bulb and you need to get the single beam buld. get it at xenoneyes.com and the the 6000k. The 6000k look the best and is the brightest trust me you wont be let down they are brighter and last longer than the standard halogen bulb um also and like 5 times brighter. they are 129$ at xenoneyes.com thats the cheapest price that i have seen and they are a great value and good quality just dont touch the bulb. oh ya if you replace one headlight do both it looks much better. maybe try this web site to show you a little bit of how to do it
