Audi A4 Part Number Help.

[550Anniv]

..Can anyone help with this please. My friend has an issue with the DAB on his 2011 A4 TDI Black Edition Avant with the signal dropping.
He wants to change the DAB aerial amplifier, however it proving a tad difficult to find out the correct part number for replacement.
So if anyone can advise of the latest part number, I would be great full.
Thanks for all your help.

The single easiest way is going to be for him to call his local TPS, give them his registration, and ask for a quote on the part.

They'll then be able to tell him the latest revision of that part from Audi specific to his chassis number.

The DAB on both my A5's have been crap (constant lost signal in built up areas) so I'd be sure there is actually a fault before spending on replacement parts.
