The start of production of the Audi A4 B5 is 1994. With minor changes, it was produced until 2001. At first, only the sedan version was available, the station wagon (Avant) appeared a year later. This material provides information on relay circuits and fuses Audi A4 b5 1994, 1995, 1996, 1997, 1998, 1999, 2000, with an assignment of their elements and locations.

Can't get much clearer than this. Relay 4 is one plus 'Additional Relays 23 and 24. Plus fuse 23 and 24.

A4 immobiliser problem

pull your radio out of the dash and get the numbers off it and call your dealer

Steve , it located above rear muffler I included a photo of it

On my '03 A4 it is in the trunk, on the pass. side. You have to remove the trunk floor and carpet on the right side of the trunk and it is bolted to a bracket. I removed the whole bracket. Dealer wanted $800 US. Found one on eBay for $65.

Hi Secondorama,

I having the same light in my car? Did you figure out what this light mean?

Help,

Thanks

More than likely the fuel pump. This may sound stupid but take something and give your gas tank a bit of a thump. What year is the car?

Could be thermostat this regulates the water flow around the engine to keep it cool sounds like it is sticking open when water gets hot!!

Here is a manual, but you have to purchase it:

Hopefully you've gotten this answer already, but this might help someone else, too. The amplifier is behind the rear passenger trunk panel. You have to pull out the middle plastic piece that goes over the trunk latch, put the trunk luggage spacer up, and pull the panel out. There is a 12v outlet, domelight wire, and pop fastener, then just pull hard to get the 2 clips. I have a symphony 2 BOSE, and there is no subwoofer, but I think they are in the same place if equipped.
