Hi!

I bought my V8 last january. The car runs like a dream, and I really love this vechile!
When I bought the car, I nearly got no lights at all. I bought new switches, the right(445 953 03 F) and the left(443 953 513 L). Now the washer at least works, and I'm allowed to turn on/off headlights. But, still my warninglights(blink in all corners simultaneously) don't work, neither does the Full lights(don't know the english words, excuse my bad english). When I pull the switch forward to turm full lights on, the headlights getting dark, as they should, but the full-lights doesn't turn on.

One last question. The switch that adjusts the washer, can be pulled forward, when I drag it towards the steeringwheel I spray the windshield, but what should happen when I push it forward?

This personal web site, not mine, has a full set of wiring diagrams, it is for the American version but should be the same for LHD models and help you sort out your electrical troubles. As to your washer switch, mine does not push forward, it has a high pressure switch on it and operates the normal pump when pulled, but then my car is a 1990 3.6 version. I am receiving a full printed workshop manual in the near future and may be able to help further in several days time.

Stig,

The light switch at the steering wheel is known to fail after time. The problem is that Audi puts too much current through this switch and eventually the plastic connector begins to melt and your electrical pins don't make very good contact.

Some have been able to repair this connector, but others have had to replace the switch itself (can be purchased new from the dealer for $$$, of from EBay for $$).

Once it is fixed, you may want to invest some money in relays for your lights. You may find this link useful:

You can build your own harness (so the current running through your expensive light switch is to drive low-amperage relay coils, not high-amperage headlight bulbs), or purchase one that is already manufactured for that purpose. These professional harnesses have the correct connectors so you simply unplug your headlight bulbs, plug in the new harness to your bulbs, into your factory headlight harness, and supply 12 Volt + and ground. Very quick to install and it does not require cutting your Audi wires (so you can remove this when you sell the car). As an added bonus, you are able to increase the amount of lumens that your bulbs are able to produce with their increased current.

I hope that helps,
