My rework friend can do this in less than 10 minutes, professionally. This is child play :-) Even I can do it, but always leave to the professional.

I may create a fixture to read the data and program this simple EEprom so I can do this CP thing for $20 a shot?

Cheers,

Louis

1. We need to unplug the head unit, expose the AT24C64 8 pin IC. We will use the power from the USB programmer to read the data and save it.
2. Buy this USB programmer http://amzn.to/2vnRn7O
3. Buy this IC clip to clip on to the AT24C64 on board, make sure pin 1 is correct. http://amzn.to/2fu0ik5
4. Watch this video and download all the correct files for your computer.

Got to love technologies these days :-)

Whoever volunteers to be a guinea pig and tries this out, please report the results.

...which will do the job. Can think of any other way they would be able to do so.

Louis, you KNOW you want to be that rodent. Bite the bullet...

Thanks for the viddies, and (as usual) your understanding of this shiite never ceases to amaze me... Mad props to you, my friend the mad scientist!

Thank you for the vids, too, Scott! Welcome to AW (like I am some sort of amb***ador). I hope your Cramps get better soon. (Haven't you been here more than 162 posts? Or is that on another forum?).

May I suggest those of us dissatisfied with Audi customer service CALL AoA and TALK INCESSANTLY.
I am convinced that they are not allowed to initiate the close of conversation.
Their algorithms (VWAG is BIG on algorithms, in case you haven't heard) probably assign greater "weights" to longer calls, and, if I may speculate, calls which mention a particular competitor.

Mercedes-Benz has a "Classics Center" which can provide any part for any car Daimler-Benz EVER PRODUCED (at obscene prices, of course); but the point is that Audi seems to WANT to recycle its cars -- instead of building on the durability aspect (wonder why) and to recycle their (our) aluminum. (THE most recyclable metal on Earth, infinitely reusable - unlike other metals, which need to be analyzed, renewed, and analyzed again (no homo) for properties lost during recycling.

We need to rise up against The (Ger)man, and tell him this shiste don't fly in the US of A.

Got any friends with a 2004 Lexus? Ask them if you can drive their car in to their dealer for service. They practically blow you.

Audi doesn't seem to value its repeat customers, unless the "repeat" comes every year or so.
NOT a sustainable business model.

I think you mistaken me with someone who likes to break his/her own car. "If it works, why fix it" as I always tell myself. So, if for any reasons, my Head Unit is dead, and I have to replace with a new one and CP appears, then I'll try it.
I just got all my stuff ready for kick the trunk to get it open, haven't had time to do it, it will be amazing if it works.

Cheers,

Well....took the car to the indy shop that is Audi authorized to remove CP....the mechanic used to be the shop foreman for the Audi dealer. He tried for 2 hours and the CH would not respond to the Audi diagnostic equipment. Same thing the dealer told me earlier this week. His conclusion - the unit is defective. So out it comes, and back it goes, until I can get a replacement. All of this for a rear view camera....

ScottCNelson

...the dealer is right. Still, these dealers refusing to even try to remove CP are outta line.

Recently, I took my S8 in for bad rear footwell heaters blowing both fuses and throwing codes. They fixed the right but CND'd the left. Sometime during the drive home, the left blew its fuse again. First bring back, R&R fuse could not get it to blow again. Drove it for a week and VAG found "fault in left footwell electrical circuit" but did not blow fuse. Second bring back, tech calls me and says ODIS indicates the failure code is invalid and can be ignored. Huh? AUDIs throw specious OBDII 2 codes that can only be found as such by AUDI special sauce code scanner? Nice diag code and a business model that gets your most committed enthusiasts to bring mich Werkstette for no good reason.

There's a reason why my sig has an AUDI lemon pic!

ScottCNelson

Dealership treats her like a queen. But then, it's a Lexus, so all it's ever needed is regular maintenance and a battery. BTW, I pull codes on it monthly, I never found anything other than the bad bat.

Out of interest, did the Q7 Control Head have an A8 part number [4E0 ...] or a Q7 one? If not, maybe a 4E0 version might be a better bet.

And by the way, I replaced my original A8 'beeping' sensor system with the later ECU that gave the graphic display...

And I still look out the back window when I'm reversing

Yep, Q7 CH was 4E0 035 729A. Even came with 4610 firmware, same as I have in the car. My original was same part number, but without "A". I'm sure I'll keep looking out the back but the vision is limited, I know a RVC will help. The eBay outfit that sold me the CH is on the lookout for another "A" unit. Meanwhile I'll swap my old CH back in, at least I'll be able to listen to music again.
