NZ: Gateway module replacement - is CP removal involved ?
Hi ... quick question - I replace Gateway module - is Component Protection removal involved ?
if NO, it's goooooood .... if Y :
-) only gateway module ?
-) gateway and other modules ?
-) other options ?
thank you for response.

thanks for your reply ... I have the same not sure thought ... well educated guess....
at this moment the only way for me is to do it and see what will happen .... disappointed with absents 100% sure info
I had chat with a Auckland dealer, with foreman of diagnostic team ... and guess what he said ... he sad EVERYTHING in MMi system after replacing Gateway module (incl Gateway module itself) needs to be process on CR removal ... I asked again everything? .. including radio unit? - he said YES. .... HOW CAN I TRUST a dealer if Radio unit doesn't have CP ... I do not have a choice ... dealer holds monopoly on Audi plant server information (I cannot pay for monthly subscription) ... they treat us as idiots. I try to be diplomatic when I describe my feeling about dealer service.

Ive got an indy guy with Audi ODIS here that only charges $65 for component protection removal, might call around to indy shops and ask em whom they use if they encounter component protection.. they might have a guy who they outsource that too, its how I found my dude.

My question is why are you trying to swap the 'gateway module' in the first place? Does it REALLY need to be replaced, or are you simply having some troubles you think it may help to resolve by replacing the gateway module? Audi most often replaces modules rather than troubleshooting them, but often you can simply use a Ross-Tech VCDS to go troubleshoot and do some maintenance inside the module to reconfigure and get it working correctly again. A lot of owners just start trying to replace stuff on the Q7 w/o actually knowing what the best course of action really is, and not realizing that a weak battery creates havoc on this car internally, and can result in some extremely weird symptoms, so do be sure you are headed down the correct pathway before jumping.

thanks for sharing thoughts .... initially a thought to replace GW module was an another step of solving battery management module message 01299 - Diagnostic Interface for Data Bus (J533). Battery could loose charge after 2 weeks of not driving or went down to 10% after 3 days ..
Battery is new (1 year old), internal resistance 3.2, full in charge now and I always use CTEK MX40 when work with the car ... and of course I have legitimate VCDS
After replacing programming 2nd working BM unit I had the same 01299.. Wiring can be a problem but to get to GW module to "ring" all wires I had to remove GW module. to remove GW module it is the whole STORY , because is it buried very deep under the dash. Since I have original GW module on my hand (replacement is coming) I decided to replace it and see how the system responds. If gateway module has it's own CP , I will be get stuck until CP is removed, if NOT, battery management has to respond ( I know the unit I bought is in good working condition ) .
... would be very helpful to have wire diagram to "ring" cable from BM socket to GW module socket while I'm waiting for delivery .... can somebody help me please with wiring diagram if it's possible?
... that is the plan ....

So, here's a thought; scan your car for door handle specific errors for the proximity sensor and/or exterior handle lock/unlock buttons...Q7s all get them, and they cause parasitic battery drains constantly. Once identified, follow the simple directions in 'Got Parasitic Drains' thread to snip the power wire lead at the external door pillar connection. Clear all errors; see what returns. Others have also reported disconnecting the small monitoring wire lead from the battery post itself, will allow the car to charge the battery at a higher overall amperage rate, and bypass the 'monitoring' feedback loop from that sensor wire. There are also a number of relays that get old & cranky, and possibly corroded, located under the seat next to battery, that are relatively inexpensive to swap out. You can also ensure your current battery has been coded into the car's BEM system properly, and update it if it hasn't been properly coded into the car.
None of that requires much time, effort, or cash, and you don't have to worry about security-coded modules.

very much appreciated for the collection of points to look at ... collection of experience and wisdom ( I'm serious) ... I have strong believe the whole idea to have a Forum it’s collection of experience and share.
ok ... my first scan after purchase showed handles sensors fault (all of them) ... I bought new handles ... they sit on the bench, waiting to be installed ... I have to admit after checking youtube video handles replacement, I am still a bit afraid to do this job ( it looks to me as “guess” job – nothing visible to manipulate with … or Am I overthinking? ) … found two video but they are in russia lang ... they look convincing ... will try to do job on weekend
… relays – Yes, bough 2 weeks ago some, still travelling somewhere – weird service during Covid time.
… thanks for the tip “small monitoring wire” will look into it deeper …
My life is very busy with work … only weekends are for cars … will report of my results after weekend.

The door handles are not worth the cost, nor the effort, IMHO; you can just snip one wire at the door pillar's exterior connection point to eliminate the parasitic drain issue. See my "Got Parasitic Drain" thread on exact steps. It takes all of 10 minutes to do all four doors, or less, and problem solved w/o tearing into the doors to get at the handles. Handles still retain their double-pull to unlock capability, which works flawlessly once you snip the wire to eliminate the interference/noise/grounding issue from the proximity sensor and/or handle button.
You will find out that those constant parasitic drains take a heavy toll on the battery over time, which leads to all sorts of bad behavior in this highly voltage-sensitive car, which is networked from end-to-end. Fix the parasitic drains, clear the errors, get your battery voltage and amp hour capacity/internal resistance #'s back up to where they should be, (replace those old relays) and re-assess.
