I was driving a corner in the parkade I live in, and it went off.. plus message on the panel "Right Dipped bulb failure".

Looking at vag-com - I get this now

1 Fault Found: 00979 - Lamp for Low Beam: Right (M31)
57-00 - Electric Circuit Failure
00979 - Lamp for Low Beam; Right (M31)

Any idea?

I'm tempted to pull apart the wiring harness and see if something is loose inside.. I took the headlight out again today, took a look at the bulb everything looks good.

Any idea what electric circuit failure means? Break in the wiring somewhere?

could be the ignitor, test the bulb by checking the continuity runing through it with a volt meter.

 

I swapped the other working bulb back... is dead also. So - that most likely means ignitor is dead.

How much are those?

The other weird thing - the 1st time I took the light out, the harness clip came off super easy. Now.. it doesn't want to come off at all

New ignitor I just looked up is about $930 I can get it a bit cheaper save you a couple hundered bucks but your best bet would be ebay.

 

what a rabbit hole I have uncovered..

Searching on Ebay, for the ballast - Audi Part # LAD5GL, it turns out, its actually used in a variety of vehicles including Chrysler...

There is an equiv mopar part # - 5139061AA - from what I can determine, I can get the 'Audi' one used, for like $150 plus shipping, the chrysler part looks like it goes for $50 NEW at the dealer

Talk about rape and pillage... I'll try to find one in town tomorrow!

Now this is nuts. the other one went. Quick question - disconnecting the harness on the ballast itself, I see with the lights off, basically 0V. With the lights turned on, like 11.67V.

If I disconnect the ballast completely, should the the fault change at all? It just says circuit failure-

I tried disconnecting one of the other bulbs in the light, I get "circuit failure" when its disconnected, and see the same voltage.. so I know there is power going to the light.

Just seems weird, new bulbs, burnt out the old ballasts.
