Fuse Type & Size

Audi A4 uses two types of fuse sizes. Fuses are very inexpensive when purchased online. You can typically get a box of fuses for under $10. You can purchase these fuses on Amazon by clicking on the links below.

No Headlights

Do you have a 12 volt test light or a volt/ohm meter to do some testing?

turn on the lights and check fuses # XXXXX F2-46 and F2-47 in the central junction fuse box, need to know if there is voltage on both sides of the fuse, here is a diagram of the junction box.

the power from the headlights runs through the multifunction switch before it gets to the fuses for the headlights, that last fuse you checked is before the switch, so we have power there just nothing out, here is the wiring diagram for the headlights, the problem is in the multifunction switch(Turn Signal switch), you will need to remove the steering column covers and inspect the harness connector to see if there are any wires pulled loose from the connector, if the harness is good then replace the switch, hope this helps.

It appears that all these are on a single fuse. Locate the fuse box under dash near the steering column and remove the cover. A fuse diagram will be on the back side of this cover and will tell you which fuse to replace. Owners manual will tell you the same.

These systems are controlled by the Generic Electronic Module (GEM), have a self test run on the system by Kragen, it is free, post codes here.

but most likely the Module is defective, it is located on top of the fuse panel to the left of the steering column. I have 30 years as a Ford tech so I am pretty darn sure of this diagnose.

This could be a combination of electrical issues, although i feel that the timing is coincidence in this case. When the combination is elec. windows, wipers, and dome lights this is indicative of the GEM module located behind your radio. The GEM (generic electronic module) is an electronic body control module that regulates electrical flow through a number of accessories. 

These factory module boards are notorious for acting quirky by failing to ground intermittently until failing completely. I would be cautious in replacing ignition switches, locks, etc. as the issue can be also compounded by corrosion of the main battery ground wire in the engine compartment and which can cause frying of your under dash wiring into the main wiring harness which can get expensive (i speak from experience having had the exact same syptoms). My issues were that these symptoms occurred only in full ON. When in key BACK ACC mode, they disappeared.

New price for one of these modules is around $280-$300 and easily replaced.
