Xenon Flickering issue: Working on it

[fly300kts]

Hi Guys,

All the Xenon Guys are aware of this infamous issue that could end up being expensive to fix. Cheaper way around is to try the bulb replacement first but sometimes, the ballast is the root cause.
I decided to start a little investigation of what could be the problem and I finally was able to separate the board from the housing.

Well I am glad to tell you that I found the problem!!!!!
This ballast was totally shot: once powered, bulb was coming ON for a millisecond and that's it.
Replaced Transformer, capacitors, regulator and voila!!!
It seems that the components are made in Germany (same components used in the aircraft I am working on) and Mouser or other, don't carry them
A total of 4 components need to be replaced: 2 are faulty and 2 are weaken due to the faulty one

2 capacitors
1 transformer
1 Regulator

As previously said, I got these from my Company stock and we have specific parts numbers. I will need to go back to Engineering blue print to see if I can get a cross reference.
I hope by adding this, the post won't be locked, but for info, the total part cost for 1 ballast is $59, way better than a new unit !!!!

Well, if you have a flickering issue, the Community has now a solution!!

Nice! Ive only had the flickering once and it was due to the bulb.. The ballasts are original OEM....

Good to see some progress on this... such an annoying issue to deal with and I've been dealing with it for 1.5 years now. I can't believe this hasn't been figured out and taken care of by Audi.. it is an extremely dangerous problem. I can't even begin to think of what other drivers are thinking when I'm driving by and my lights are flickering like crazy at them. Embarrassing.

Yikes Audi should hire you or just send all the ballasts to you for fixing. :-)

Sweet, need to keep this in mind. A lot cheaper soldering a new transformer, capacitor and whatever else that needs to be replaced vs buying a new control unit!

[brucebanner]

you really should be in contact with them, see if you can sell the solution to them for a price, lol

speaking of, what would the cost of this repair be for people that have the problem?

[Tanner]

I doubt Audi would do anything given that the whole control unit is probably manufactured by somebody else for Audi, but I do see an opportunity where somebody could fix these things and charge for it vs replacing the whole thing. Just like the guy here in Toronto that replaces the red DIS on the B5 and I think B6/B7s also when part of the DIS starts to fail.

Guessing it's that orange thing being the capacitor that was replaced, which transistor in that image was replaced? Have part numbers?

Just curious than anything else right now. I am dreading the day when my ballast goes south.

This great, but there is something I don't get. I was under the imnpression (after some reading of az threads) that the flickering was caused by the vibration of the Bulb due to some plastic part in the headlight coming loose or something and not the ballast. Basically this is the reason most everyone changes out the bulbs and the flickering is gone. Well at least for a while. Is this accurate?

You are mixing different issues here:

1/ When healights are switched ON, one or both bulbs starts to flicker or even shuts off. This can be triggered by a defective bulb or ballast. Cheapest route is to replace the bulb but problem can be the ballast. Ballast cost is in the $300 plus range a piece.
2/ When headlighs are switched ON, at idle, you can the the main beam shaking. This is due to wear in the levelling motor (I also addressed the problem and solution on a different post). Audi has also released a TSB to cure or attenuate this behavior.

Hope everyhting is clear for you now

Phil: This is great news and will be even better once you get more details about the parts.

My guess is that, the malfunctioning bulb eventually makes the ballast components fail. I had intermittent flickering when accelerating and decelerating during the first few minutes after after start up. Eventually I changed the bulbs, and the issue was gone.

Well, actually thats a lie. They did once but I believe that was my fault and I'd rather not talk about it. But thanks Phil!

[the director]

This is great.

I had really bad flickering and dipped headlights on both sides until I replaced the bulbs and now it's only on the passenger side. Although if I turn my car/lights on and let the car sit in idle "warm up" the lights, it seems to not have the issue. I recently drove from SLC to Phoenix straight through at night and didn't get a single flicker both ways. But if I jump in my car to drive 2 miles to the store without letting it warm up i will get flickering right away and a dipped headlight shortly after.

I haven't checked to see if it's a bad bulb yet but seems to be the ballast. Either way I'd probably rather replace the ballast components the next time I pull the lights anyway.

both of mine flickered and both were due to the bulbs.

[BLUESTEEL]

wow,i just got my car in Feb. and recently started noticing the passenger light was shakey,i figured it was the leveler going bad so i took it to the dealer being that its still under warranty.The dealer told me it was some sort of rubber washer/gaskets that dryed up and when replaced would resolve the problem,well im curious to see if they are correct,my appointment is next friday.

[Mc Suly]

HOLY SHIT!
Will get you to fix mine.

Hope it works.

Problem if people are wondering:
When headlight mode is turned on=
When coming to a stop it flickers 1-3 times, Then goes back to normal. Also braking hard. (Trying to adjust or something)
Only flickers once when driving. While flickering I see the white go to yellowish bulb.
After 6 minutes of driving everything is completely normal.
It's not dipped headlight because i get no error. Not sure if it's bulb...no error?!
I'm thinking defected ballast.

[fly300kts]

It looks like the ballast does not longer regulate the voltage sent to the bulb

Phil

[tecnica]

phil does it again....

[Flapjack36]

I have found that my dipped highlight error occurs more when the headlight switch is turned on the "auto" mode, then when I turn them on manually. I don't know if this actually related but I have started to get the headlight dipped warning a little more frequent. I am really curious about this fix because this has happened on both left and right headlights now.

This is normal because in Auto mode, the light sensor does trigger the ON command while you select Headlight ON, you bypass the sensor

Phil

[NERO Quattro]

Installed new bulbs today and dipped error is gone ( [>_>] not long how this will last.) ^^^ Interesting, I may start to do turn them on "manually" to avoid errors in the future or I may just send them to Phil as a precaution....

Hello all, this is my first post. Looks like a great bunch of folks posting here.

I am on my second leased A4 (wifes car) and just purchased my own CPO '08 B7 A4 SE yesterday. Well wouldn't you know it... my right side headlight dipped twice while driving around in the early evening with the switch in Auto mode the first time, then in the manual "On" position the second time.

I have 11 months left on the 4 - 50 warranty so I am sure going to to have the dealer look at this.

[golfvdude]

This is fantastic! You did it again Phil! If it's anything, I can definitely solder! I did have the problem early on when I purchased the car, but I changed the bulbs and it doesn't do it anymore. Good to know I can purchase these parts and swap them out if needed. Thanks again!

P.S. Taillights are still going strong!

Just revisiting this, i see what were replaced but i don't see the part #s for the two capacitors, transformer and regulator.

I just found out that there's a high end audio shop that sources electronic parts from Germany so that got me thinking....

Read the entire post Tanner. I am not able to cross the PN replaced since the parts are Aircraft references

Phil

[Tanner]

Understand the part of the cross reference that you can't post, but was hoping to see if the part number of the components that were originally in the ballast that Audi used then I'd try and see if somebody locally can source them or even the guy next door who works on aircrafts....

Either way, I'm sure we all appreciate your help! ANd the cost is VERY reasonable compared to buying a "used" ballast. Can't wait to get mine back and be rid of the errors on the display!

[papadelogan]

Part #'s would be great but like Phil, my main concern is that mine are fixed. If he can get part/reference #s that's cool. If not, well, he's still been able to help us out with a fix for 1/5 the cost of a replacement, and for that, I'm incredibly thankful.

[estanenmi]

Hi

I have reviewed the ballast of my audi a4 b7 in Mexico with the problem of vibration and momentary shutdown of the xenon bulb ... I found opening the ballast that the problem is the transistor that is marked on the black circle in the photo annex, the part number is buk9628 to 100 amps and needs to be replaced ... the other says the other pieces that do not require post because if you fail to change will not work at all the ballastro ... (need to check that theory )....

the part is readily available in your country in the electronics stores in mexico is very easy to obtain and cheap ...

greetings!

[2.7turbo]

So I'm reading through the thread and the spacer issue sounds interesting - so Audi actual made spacers to fix this specific issue? I've replaced both ballasts on a B7 my06 A4 with adaptive bixenons and still have a brief flicker. Will the spacer keep the transistor from shaking (spacer and transistor - substitute or complementary fix) ?

[fly300kts]

It's not a spacer, it's a shim that only prevents main beam vibrations at idle, not flickering

Phil

[whodat]

Hi all,

Any way for us to pinpoint if the issue is with bulbs vs ballast? I plan on taking my b7 S4 to my mechanic to fix the issue since it requires the removal of the bumper. So, I was hoping to fix only the bulbs if I can pinpoint the problem.

For me, the driver side headlight flickers, changes colors then cuts out. Other times it just flickers and changes colors (more yellow than blue) and stays on.

Would you say this is a ballast issue? Or can I get away with just a bulb replacement?

Thanks Phil, this info is awesome!!!!

[fly300kts]

This is a hit or miss situation:

It might be only the bulbs but, if the ballast is damaged/weak, it will damage really quickly the new bulb ignitor and you are back to square one
Best way to get rid of the issue, repair the ballast and install a new set of bulbs

Phil

[whodat]

Makes sense. Thanks a ton!

+1 its the bulb dont waste your time or money

[Tanner]

I had the flickering bulb then it shut off completely, turning off the headlights off and on got it back alive, and most of the time it would they stay out. Problem got worse to the point it would stay off and wouldn't light up, ballast was the issue.

[milk]

My headlights "shake/vibrate" a little bit when starting from a stop. It seems it's from the initial rev of the engine from an idle. Not too bothersome but it is there and makes them look sorta cheap, IMO. I had my '07 GSXR 600 retrofitted with two Morimoto ballasts and everything and even on a "race bred" motorcycle the shake or vibration isn't there, or not as bad as on my B7 A4...

Thoughts? Is this a precursor to any of the issues that Phil addressed in starting this thread? Or is it normal?

[fly300kts]

I guess your car is an 2005.5 or 2006
This behavior comes from wear on the adaptive motor shaft and pivoting point of the bakelite projector chassis
Audi has a TSB on this asking to insert 2 rubber shim between the headlight housing and the front frame. To be honest, I have seen and tried the TSB, with no luck
I ended up replacing all the internals (motor and chassis on my headlights)
No, this has nothing to do with the flickering

Phil

[helli217]

Just to update I had the shaking, and the passenger headlight dipping here and there. Replaced bulbs with new OSRAM, and shims from Audi. Profit on both counts-headlights are now rock steady and haven't had a dip since swapped last October. Additionally the new bulbs are MUCH brighter than the old and have a way sharper cutoff. About 90.00 for both on Amazon.

[NYRangers86]

Forgive me but this is pathetic...So you're telling me that if you have a flickering issue, change the bulb. If that doesn't work you need to fork out your own dough for ballasts? And from the looks of it, that doesn't guarantee a fix. And the vibrating, Audi came up with a ghetto rig that they still charge for? And after all this, they can still flicker or even go out?

I used to be an Audi tech and now just do side work while working my day job - what seems to fix this from start to finish is a fresh bulb and a new ballast. Just my 2c but pointless to fiddle with one or the other, just replace both. In regards to the 'Audi fix' - yes it's ghetto fab. It's a triangular piece of rubber that when pushed in between the headlight and the radiator support supposedly reduces vibration. Shouldn't be a problem if you adjust your front engine mount so that while the drive gear is selected is not fully touching the engine mount support that is mounted on the radiator support. Oh - and GO HAWKS

[Tanner]

Well, aside from the flickering issue if the ballast/bulb is fine (usually I see this when driving over rough roads and guessing the hardware for the adpative headlights can't keep the light steady), this is the troubleshooting steps to go through. I'm not expecting the xenon and ballast to forever, especially that my car's over eight years old now (did have a ballast fail on me on year two and a xenon earlier this year).

Forgot to mention - same steps used when you have to replace the fluorescent tubes. Sometimes it's a bad tube, or the ballast, or both.

I know this is an old thread however I wanted to share my lighting problem and give thanks to Phil (Fly300kts) for fixing it for me. Now our cars are 10 years old we expect sooner or later to have a headlight out of even flicking of one or both headlights. In my case I had the flickering even after replacing both bulbs with Osrams. I knew then it was ballast time so I looked at used ones around $150 and new ones around $400 then I remembered my buddy Phil. I sent him a PM and he got back to me the same day with his thoughts on my problem. He agreed to rebuilt my ballasts rather than see me get hosed by buying used ones or new for that matter. I shipped them Tuesday as Phil needed 24 hours to fix and test them before sending them back. If you have dealbt with Phil before he is a top notch guy who is very good at what he does. So it worked out I had no headlights for 2 days however they work like a charm again.

Thanks again Phil for the excellent work and communication.
