B153313 - GSM antenna 2 Open circuit static

[j0hnny5m]

Evening Everyone, I have a 2.0L A6 S-Line 2015. I've recently got a copy of VCDS to code Red LED Door Warning Lights and puddlelights. These work a treat.

Whilst scanning the car I have the following error B153313 - GSM antenna 2 Open circuit static. I'm trying to determine where the fault actually lies. I've taken the headlining down to check the shark fin, there are only 2 cables attached.. BLUE-GPS and one PURPLE one which I believe is for GSM antenna 1. Can anyone tell me where GSM antenna 2 is located? I'm trying to find the cable location to see if it's physically broken or disconnected.

Here's an extract of the error from ODB11:

I have the MIB 2 MMI installed with the dual SD cards slots and SIM slot.

*** Does anyone know where this module is located 4H0 035 456***... It appears to be the GSM amplifier module... Of if someone can attach a diagram of the MMI wiring I'd appreciate it

I had the same error, the GSM antenna's are located behind the rear bumper, burgandy little things, one each side.

The fakra connectors are ***** and break, as the male part is integrated into the antenna and degrade. Mine degraded and water and crud got in and led to an open circuit.

The antennas themselves are pitted with road rash, so not an ideal place for that kind of equipment. That module you mentioned above is located at the back of the rear boot passenger side cubby hole where the towbar bowden cable is accessed.
