I'm back to the dealer next week on some other follow up, so I'm going to put it on them for a start. One more thing: does the tint effect both AM and FM? And would it completely eliminate AM reception. (the radio scans for am stations and comes up with nothing in either local or distant setting.)

It did on my car. I removed the tint and reception for AM and FM both came back.

I don't know about that - unless your metallic tint is in the line of sight of the radio signal (e.g. your antenna is inside the car). Seems a bit specious.

More than likely it's the antenna. VAG products use amplified antennae for AM and FM. When the amplifier (contained in the antenna base) goes out, this is exactly what happens - no AM reception and lousier FM reception. I've had it happen on three VWs.

Got my car back from the dealer yesterday. When I picked it up the rep. told me they ordered a new amp for the antena and I scheduled a retun visit. So I go out, start up my car, and bam, there's AM reception and better FM. I went back inside and basically said WTF to the service rep. He gave a deer in the headlights look, said "maybe there was a loose connections, but the amp needs to be replaced, and it's under warranty."

Not that I don't think a new amp is a good idea; but it kind of makes me wonder about what's going on when I drop my car off for service......

2002 A4 had fried amtenna booster with broken SMC. Audi diagnosed it as bad - rather than allow my dad to pay 500+ dollars, I had him buy one and I replaced it for him in 3 minutes. It immediately fixed the bad radio reception - for 9 seconds - then it goes back to like it was with the broken amp. I thought it was a heat problem, but it is always 9 seconds regardless of how many times i fire up the radio. Each time I fire up the radio - it works fine for 9 seconds then PPFFT! Anyone heard of this?? This is the updated board revision ending in "P."
Thanks!!

Can someone tell me where the antenna amp is located and how to get to it? I have no AM and FM is compromised. Thanks.

What is likely happening is that the antenna boost connection was loose. I found out about this little function when I installed an after-market radio on another car. If the power boost wire is not connected to battery voltage, FM is weak and AM is gone. Connect it and presto, great reception.
