Component Protection Query

**Boy** · 30-06-2014,09:51 PM

I shall also probably need CP removed from a DAB concert head unit which I have acquired for my A4 B8.
Does anyone know what it wold be reasonable for a dealer to charge for that?

I've tried the DAB Concert head in my car and although it seems to work, there is no sound.
Is that (1) component protection
(2) coding requirement
or (3) a need for me to tell my car with VCDS that it has a different head unit?
It has not shown any message asking for a code.

I'm pretty sure this is component protection. I had it when I had mine changed. Be aware you may need different extra wiring for the dab signal to be received as well

Thanks.
I appreciate that I shall need to connect a DAB aerial.
My car is it the dealer now and they say that they have removed CP
but that it still makes no sound! I am wondering if they did it properly.
It was asking me to switch on the ignition to overcome CP and when I did,
the screen would show stations etc, but I had no sound.
Does yours still ask for the ignition to be turned on?

Hmm that's strange. They removed the protection from mine and it worked straight away. This was around 3 years ago and not a single issue since

Thanks Greg,
Perhaps they have not done it properly!
I shall report after I get the car back on Monday.

Audi Doctor, that was exactly what I was hoping and as soon as I got to the car this morning I changed the wavelength and immediately had sound. The Audi tech had just not tried that.
So now my new head unit works and I just have to sort out an aerial. I am nervous about buying an aerial amplifier on ebay without
knowing what part number to go for. Does anyone have an advice?

Hi.
I have just installed a second hand Concert Headunit into my A4 (mainly for the 32gb SD functionality) and it needs the Component Protection removing.
My car is booked in with Audi tomorrow, however, I received a phone call from Audi yesterday saying they might not be able to take off the Component Protection because it is from another vehicle. Is this true?
I really hope not as I'd have to put my old headunit back in and only have 2Gb SDs :-(
