FM Radio Reception - where is the booster/amplifier and what part#?

[Addie]

I have a 2007 A4 Avant, the FM radio reception is very poor outside of built up areas (GPS is fine) so I figure the booster must be at fault.

Could anyone tell me where it is located on the Avant and the replacement part? Is it same on the Saloon/Avant? I understand there are a couple of different part numbers to look at - is 8E5035225D what I need to be looking for?

Thanks in advance

I could be wrong but I think it’s in the boot. Behind the trim panels on the passengers side. I found a couple of pictures from when I was doing my audio install which might help...
