Question about 2003 Audi A4 Cabriolet

1 Answer

A4 Cabrio (53) lost radio reception

CD works fine but no radio reception (or very poor with lots of hiss). Wasted £200 replacing both boosters in the boot lid but problem persists. If I touch the coax inner core with metal object then reception is perfect (which is why I assumed it was the boosters) but plugged into booster it does not work. I assume that there is a break in cable so no power to booster but central coax is fine when I act as antenna (if that makes sense). I assume that part of teh coax is a power supply and its that which is bust - can anyone confirm
Any suggestions apart from paying huge sums for Audi to re-wire.

Ensure you have power from the radio feeding the booster/pre amp.

SOURCE: 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.

SOURCE: bad brake booster

If you know for sure that the booster has failed, you need to unbolt the master cylinder from it, (sometimes you can move it away enough to not even disconnect lines.) Then unbolt the booster from the firewall, disconnect the pedal linkage if connected to booster. Remove & replace booster assembly and everything else you you took off. If you didn't have to remove master cyl you are done. If removed, bleed master before putting back into service!

SOURCE: No AM radio reception in my 2002 Audi A4

do you get any stations, even weak stations on the AM band?  If not you have a bad radio and need replacement.  Try having someone hold the antenna as you scan the AM band.

SOURCE: Slight air hiss or sucking sound near brake pedal and no

It maybe, I don`t know the vehicle personally but on Trucks and Buses, when this occurs, it usually points to the master cylinder piston seals which moves in and out as the foot pedal is operated. Does the hiss alter as the pedal is pushed down?? Does the hiss reduce or increase as the pedal is pushed down?? If it does, I think you`ll find that it`s this air seal between the piston and cylinder that`s failing and not the servo. Whether you car works the same way, I don`t know but I presume it must. Ian

Stock radio reception


There were 17 entertainment systems used in the 2005 Audi. It is possible that the aftermarket antenna was connected directly to the radio, bypassing the Audi antenna modules.

Poor radio reception on a Santa Fe that has the aerial as part of the near side rear window, is there a mod to improve reception.


if you live in a weak reception area the only answer is a signal booster or a new aerial on the roof.

It may be more of a design flaw oppose to a actual problem. However, you can purchase signal booster that simply plug between the radio and the cars antenna.

I own a 2005 jetta with a factory rady, cassette


you can try a AM/FM antenna booster if you know how to get to the back of the radio. Otherwise the radio ground needs to be checked out and the antenna ground would need to be tested to see if there was corrosion on the antenna base or the connector to the back of the radio. On some cars the antenna is located in bad area and they don't get the signal boost off of the cars ground plane The more reflective surface you have on the car the more radio waves will bounce back and increase signal strength. Also Depending on atmospheric conditions and skip conditions sun spots and other natural occurring things can cause poor reception. The signal booster is about $10.00 at any radio Shack or any auto parts store. Hope this helps.

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..

Having problems with my radio not working where is the aerial on my a4 cabrio.


I have 2003 A4 Cabrio. Had 2 radio problems - one the volume control and the other not picking up radio channels. I got a reconditioned radio from Audi for £213 which fixed the volume but the signal still not working. Read another article. The ariel cable runs into the lid of the boot - you can see it on the right. I removed the emergency triangle and behind it is the ariel wire. Wiggled it and confirmed the problem was there. Got the signal back but it might be temporary - cable may be damaged or a connection problem because there are amps behind the trim. I have not taken the whole trim off but a lot of it unclips so you can see what is behind

98 BMW M3 radio has poor or no reception. CD changer and head controls work fine. The car is new to me and I understand that there is an amp or antenna booster that may be the problem.


the usual cause of this is a defective antenna or antenna ground, if it is a power antenna verify a good ground, if ok replace the antenna, also check the coax connector to the back of the radio.

Factory radio reception failing


I would suggest installing what is called a filter capacitor.You can get these at most car audio shops or a electrolytic capacitor rated at 16v or higher and around 30uf (the capacity is not very important) you connect it from the Positive to the Negative on the radio. The idea being a capacitor will allow the A/C current (noise) to pass through to ground without going into the radio and this is usually the cause of poor reception.

Another possible cause could be simple a poor quality antenna, some manufacturers are going cheap on the antennas since most people don't listen to the radio anymore. You could try to screw an antenna off of a different car onto the base on this one and see if that clears up the problem, they are a some-what universal thread.

No radio reception on 2003 Audi A-4 Cabriolet Convertible


After reviewing the feedback on these postings I identified the problem them took it to my local car stereo shop. I showed them how by raising and lowering the trunk the signal went in and out. They fixed it for $60 by splicing in some new coax cable. It works great.
