Calling all electrical gurus (+ Wagner EM Nero DP issues)

[Lloyd]

Anyone?

[Lloyd]

From the schematic:

Brown = earth
Yellow with black stripe = Twin Filament Bulb, Left
Grey with black stripe = Side Light Bulb, Left
White with black stripe = Twin Filament Bulb, Left

Does anyone know where I can find the earth connection 119 in the headlight wiring loom?

Also, am I correct to assume that Grey with black stripe = Side Light Bulb, Left = HID?

[Lloyd]

OK will swap the plugs around and try.

Yes, both ballasts have been unplugged. AFAIK they can only be plugged in one way, right? The two little connections have an male/female, female male and the large one has a hooked clip to engage on a little stud on the ballast.

Can anyone decipher that wiring diagram?

they big plug out the two can go on both ways around, try them the other way around.

Put the WG in a vice, slip a bit of tube into the end of the flexy and lean on it (in the right direction) Sorted

There's an idea!

@ Jamo, yes that's probably the easiest way forward.

[Lloyd]

Did you remove the ballasts at any point? check the plugs are the right way as they can be put on the wrong way around.
Might be worth while connecting them up direct to a battery (one time a 3b is better than a aby/avant)
probably something simple.

You can find the wiring info here.

Thanks Nuvo

Lloyd, if you put a halogen bulb as normal, does your main beam work? that way you will know if it is just the HIDs while the wiring is ok.

Main beam is fine . Think I just forgot to flick the stalk last night, too tired....

So, it's just the HID's that are faulty..... It's odd that both sides are not working?

Can anyone label the cables in the headlight connector?

Brown = earth
Yellow with black stripe = ????
Grey with black stripe = ????
White with black stripe = ????

I've also had a look at my HID's and I can not find an external earth for them.
The only one I can see is inside the lamp housing on the back of the HID lamp plate.
It is very clean and soldered, no apparent issues there.

I've stuck a voltmeter on the plug and played with the stalk. Does anyone know the wiring layout for the plug?

@ Carsten, no problems with waterlines, apart from them needing a tweak due to large coldside housing. Definitely no issues there due to EM.

I understand and appreciate that Carsten is right about tolerances. However, as I am doing this for the firs time (and have no time) I think you should highlight the potential for issues with non stock downpipes. Perhaps add a note to your website?

That way your customers will be well informed and can ensure they allow enough time and money for the entire job, or choose to go to Audi!

For the record I would have still bought a Wagner EM but do wish I had known about the potential for issues.

[Rusty]

Have you got a connection inside the lamp? I usually wrap tape around these to prevent grounding and also to keep them all together!

[Lloyd]

Thanks everyone for your input. Much appreciated.

OK, so maybe I was too tired last night. My main beam lights DO work as expected.
It is just my HID's - both sides that have stopped working. Engine running or not makes no difference. Battery is fully charged.
