    same problem with poor reception. probably the antennae amplifier.



3 Answers

I managed to find something in the back of the car above the back seats. I removed the panel above the back window and there is a 3" x 8" black part that is attatched to three wires which presumably run up to the radio and maybe a ground wire. It attaches to the antenna that runs through the back window with metal leads. It is easy to remove both the panel and the part.

I fiddled with it a while and the radio reception goes in and out. It has a circuit board underneath and chips/resistors, etc. Maybe this is one of the "boosters". The replacement part from the dealer is $250 which is ridiculous. It is also a poor design to place this part directly under the black part of the back window which probably gets incredibly hot in the summertime. My guess is the heat fries these parts up good. My guess is the Germans don't have 100 degree heat.

I bit the bullet and ordered this part to see if it solves the problem. I'll keep my fingers crossed.

The arial is internal, it is a wire, I think it is running on top of the driver door, not sure.

Check the aerial connection at the back of the unit. Also check the wiring to the antenna, look for an intermittent connection.

On many A4 there is also an antenna amplifier, if that is wrong it can also give you troubles.

If you do not find anything wrong then the problem is on internal wiring connecting to the antenna socket, if that is the case the radio must be taken apart and tested by a technician.

I think you are on the right lines of looking at the aerial! Either the aerial is faulty or the connection to the radio! Check the connection first!

My Audi A4 1.8T saloon has lost aerial reception and every station is unlistenable, my aerial is built into the back window, any idea what the problem could be? Thanks, Jim.

It is probably the stereo.. It could be that the pre-amp (which is a small amplifier on the signal coming in from the antenia) has failed.. With out the pre-amp working the reception will be very poor..

Good luck..

Fm radio doesn't tune

check that the antenna is plugged into the back of the unit or look under your fender and make sure it is plugged in there as well or use manual search instead of autosearch

2004 audi a4 cabrio radio problem

The aerial is in the boot lid. A wire runs down through a thick corrugated tube. Many bends over time fatigue and break the wire. I simply found the break and repaired the wire , coax wire, repositioned the wire fine! Audi do a replacement around £100 that goes all th way to the radio!

NB handle in boot lining has a hidden screw that must be removed to pop off lining.
