Hi,

Got a 2018 Tiguan with no sound from AM?FM or DAD due to no signal.

Three fault entries for antenna amplifier 1,2 and DAB 1

Does anyone know if theres one that does all three ? On the boot lid under the trims there are 4 antenna amps but im struggling to find which one does what.

Having found this:


Two separate antenna's which i would bet go via two different looms into the car, unlikely to have broken wires in both rubber flex. I wonder if the screen is broken as that doubles as antenna.

Glass could indeed be broken. However, the center terminal of the FAKRA connector(s) on the back of the MIB unit can also break off quite easily if someone attempted to disconnect those recently without fully depressing the locking tab. But that would only be a potential cause to check if the MIB unit has recently been removed.

Seems to me that this issue or one similar to it came up here on the forum a few weeks ago ; check that roof antenna as a previous member opened his up and found a bunch of corrosion and "crustys" on the circuit board. (water ingress). Its worth a look.

Spent some time on this today.

The roof antenna does GPS only as far as i know. Could be wrong ??

The radio has two antenna's on the boot lid and a signal filter. I have since found out all three have been previously replaced to try and sort this.

I turned my attention to the rear screen as its not only heated but also the actual antenna. Heated screen working fine and no breakages in the elements. Both earth points are fine. The wiring from the antenna's is actually just a coax cable going through the right hand side boot flex and is intact with no issues.

The roof antenna doesn’t do FM or DAB reception. Whats stopping you from measuring the resistance of the antennas in the rear window?

The top left is FM1/DAB, and the top right one does AM/FM2. Or the other way around.

Do you mean the actual antenna in-bedded in the glass ?

Yes, It's still an electric trace with two ends.

Now like with wiring, you wouldn't be able to decisively conclude that it is okay by measuring whatever resistance it has, but you would be able to conclude that it is broken if the resistance is extremely high or unlimited.

It's part of the rear heat element though which is working so would that not rule that out ?

It would appear the radio cox cables go to the head unit in the glove box.

The screen is just a screen, glove box unit appears to be the control unit for it all. I'm going to pull it out and make sure the plugs aren't off at the back etc.

Yes, this is the case MQB platform vehicles. Only the lowest-spec radios have the "brain" attached to the screen and not as a seperate unit in the glovebox.

Also, FAKRA connector colors for AM/FM should be white and black for DAB. May help a bit to identify what you're looking at.

Dont think so !!

Erwin and Wiring Diagrams is your natural starting point.

Apologies for slow reply, been flat out in the workshop.

I found the problem, snapped Fakra connector on the rear of the unit in glovebox. I bought a repair kit and sorted it.

According to factory parts catalogue, a 2024 NAR model Tiguan has AM/FM in the rear windscreen. The sharkfin has the other things.
