As I mentioned prior, the 'customer support' folks at my original vendor (via email, cause they are in China), told me I needed to download the updated firmware version file and load that into my brand new, nonfunctional (dead-dead) Carplay unit per their troubleshooting steps. I said "how am I supposed to load new firmware when it does not boot up at all, and what's the point, since the control unit is obviously defective?"

Just sayin... You win some, you lose some. I'm hoping the third kit will be the charm for my '10, as I really want my Carplay back in the Q7.

Good luck!

 

Can you not press (and hold) your lock and unlock buttons on your key to achieve the same in the US? Saves you having to hold the key in the door...?

Curious about this... what does this entail and result in? (And I'm referring the the Cayenne shift map please).

 

the update seemed to fix the memory retention and pairing issue.
Still shuts off when I kill the ignition and doesn't remain on until i open the door, like the radio, etc. does., but I can live with that.

 

Well, because this is a TDI (both our Q7s are TDI), the 'dieselgate' detuning 'fix' to achieve emissions standards affected both the ECU and TCU programming. On the TCU it made the car upshift rapidly and not want to kick-down like it should, and it 'hangs' onto lower gears during warm-up phase only, etc; all about trying to reduce the emissions. So, now you can go buy a TCU tune from the aftermarket on several year (Gen 2 TDI) models with the 8spd tranny, but TCU tunes have only recently come available, and are not offered (yet) on the older cars like my '10 TDI w/6spd tranny. They are kinda expensive too, costing as much or more than tuning the ECU to purge the 'dieselgate detune' from it.

That said, the old-school trick was to swap the shift map in the TCU (Ross-Tech VCDS VAGCOM) from the 'dieselgate profile' to a standard, unadulterated shift profile from a different (shared platform) car, such as the T-Reg or Cayenne map, etc. It's far from perfect, as the overarching TCU emissions supporting program still applies, but feels better than the Audi/emissions tune map profile, which, btw, is actually labeled as an emissions fix Q7 shift map profile in the TCU. The idea is to switch to a shift map that is tight rather than the poor performing one that is dedicated to emissions reduction/poor performance. It's not a fix, but just something to make a slight improvement in transmission feel/action. By far the best option is simply to use the sport mode on the transmission, which is night/day better than the normal D-mode on an emissions-fixed TDI. Whenever I get to a stoplight/intersection, or turning in front of traffic etc., I pull it down into S-mode to get rid of the tranny/throttle hesitation and let it rip if needed to safely get across the intersection...works wonders, then if I want sedate, I move the selector back to D-mode.
