fixing up the inside

1. Is there any third party MFD upgrades out there or am I stuck with red/remanufactured red? The screen on my MFD has partial failure in moderate heat or cold. I found a guy who I think is in Singapore which used to do upgrades. Is there an outright swap for a newer version I could do? Found mixed reviews on searches.

2. Problem with my passenger headlight. I've swapped the igniter/bulb from the driver (it doesn't work), I've swapped the passenger light/igniter to the driver (it works). Is there a relay/fuse somewhere I can check for? Is this a ballast issue? A critter ate my wiring issue?

For headlight check fuse SB48 and check if you are getting power down to the plug at headlight housing T12q/pin6.




Headlight washer relay in panel C position #4 located drive side behind lower dash. May want to look at fuse SC36.

Cool, thanks for the info!!

Checked continuity on both fuses and both are good. This seems to be a problem between the ballast and whatever tells the light to turn on.

I think the central electronics module (BSM?) control the lights

That too, the question I have (which I lack the proper tools to fully diagnose) is where is the problem. It could be ECU, harness between ECU and ballast, ballast, or even the housing itself although probably not the case since when the igniter and bulb are out of the car it works fine on one side but not the other.

So don't know how much this matters, I ran a continuity test at the fuse in the engine bay. It has continuity. So does this mean there's a bad electrical bit somewhere or is this an ECU problem that can be fixed with VAGcom?

Do you happen to have wiring diagrams for the 06? What the build date, its located on the label drivers door jamb.

There's a guy in Newark NJ who does cluster swaps. Upgraded mine, I love it. Expensive, though. PM me if you want more info.

Check for power at plug connected to HID housing, it is a 12 pin plug T12q. Power comes down T12q/pin6 and ground is T12q/pin8. You can pull the plug out of housing and connect a test light to pins 6 & 5, turn lights on and see if test light functions. If the light works your issue is in housing. Here is a video of a test for turn signal function at plug. http://tinypic.com/player.php?v=2ntc...9#.WmC2LdEo5dg If light does not work your issue is of course in the other direction. Keep in mind when you pull the plug you will create open fault codes so you will need to clear them.

I don't have a test light, would a multi-meter be able to tell me what I want to know or do I need to grab a spare LED bulb for this exercise?

Either one, just remember that when testing with a Dvm it may shows 12v for only a short time during testing before J519 stops sending full power. Video of testing signal light with Dvm, note voltage below 1v signal off then signal turned on voltage goes up to 12v a few times before J519 cuts back to below 1v, the signal switch was not turned off at this point. http://tinypic.com/player.php?v=2pte...9#.WmDIOdEo5dg

DIY led test lights made from pen housings one for back probing the other with clamps.

okay plugged a little green LED into 6 and 8 and it lit up. so what's the next part?

For fun I took the LED and shoved it in the part where the ignitor goes, got a lot of nothing. Dunno if that should have worked or not.

Sorry I typed the wrong pin numbers in the previous post it should be T12q/6 which in power and T12q/5 which is a ground.

that resulted in burned fingers. I'm reasonably sure that the 2 prongs on the LED didn't touch.

should have asked before, do I want the key in the ignition or on position or not?

I'll grab a battery for my meter tonight and report back with more tomorrow.

Two short videos of testing pin 6 & 5 with led pen connected correctly(anode+ to pin 6 and cathode- pin 5)and with Dvm. Ignition on headlight switch on.

It started raining here about an hour ago and projected to go overnight. I'll post an update tomorrow. It seems that I'm getting power to the headlight enclosure (based off my singed fingers and blown LED) from the car which means enclosure or the next thing in line.

11.8 at the plug to the headlight housing.

So the problem is in the housing somewhere.

In looking for parts I've found there's an additional harness, what does this one attach to and can I remove it without removing the entire housing?
