no need to return it. I also bought the cheapest Galaxy tab for this sole purpose and run into the same issue in Google Play Store. You can go around this issue by sideloading the app.
In the tablet open Chrome and go to this link on Thinkdiag website.
https://mythinkcar.com/pages/software-download

Download the very last app in the list
Try to install it. You'll get a message that installing apps from unknown sources is prohibited. You'll have the option to allow it (allow Chrome) and it will work.

That's how I did in my case.

On a seperate note. Can someone explain how to do 2 things with Thinkdiag?
  • Program the key to get windows up/down
  • Access overrev report (think someone mentioned it was doable)

Thanks! That worked. Saved me a trip to FedEx. I was able to side load and it works fine now. The Android app has a lot of functionality the iOS app didn't have.

Ok so for the windows I enabled these four settings although I'm not 100% if you need the last two but I didn't bother to test without it. One of the last two may have already been enabled, I don't remember

1. System Selection -> Front-End Electronics -> Code/brush Hiding -> Rule Coding -> Coding value -> Coding value_2 -> "Coding value--Comfort functions--Window comfort open" Set to true
2. System Selection -> Front-End Electronics -> Code/brush Hiding -> Rule Coding -> Coding value -> Coding value_2 -> "Coding value--Comfort functions--Window comfort close" Set to true
3. System Selection -> Front-End Electronics -> Code/brush Hiding -> Rule Coding -> Coding value -> Coding value_1 -> "Coding value--Comfort functions--Comfort functions via door lock" (At the very bottom) Set to true
4. System Selection -> Front-End Electronics -> Code/brush Hiding -> Rule Coding -> Coding value -> Coding value_1 -> "Coding value--Comfort functions--Comfort functions via remote control" (At the very bottom) Set to true

I tried this last week, and the app failed to install/update the Porsche module internally.

For those who did the GT3 steering mod, is everyone still getting the CEL? Has anyone figured out a way to remove it?

Only the earliest 991s get an error warning. My 2015 C2S had no error warnings when I changed to the GT3 steering.

For those who changed steering software to GT3 with a Thinkdiag and getting warning on the dash (early 991s) I found the trick to silence the warning.
Keep in mind that this trick silences all warnings related to the Electric Steering but not failures (you still get messages about failures).

Instrument Cluster =>Code/Brush Hiding=>Rule coding => you get a list of Warning Configurations (0 to 5 if I remember correctly)
In one of those Warning Configurations (I think it was the 3rd) you'll need to look for item number 121 (Warning Configuration --EPS warnings--Power steering fault warning (121). You set that to 0.




btw I started a thread on Thinkdiag just to have all these tricks in one place. I learned most of these tricks on this forum (except the one above).

Just picked up a Samsung A7 Lite from Walmart. Ordering the module next.
DO we know what the yearly fee is for the tool once the first free year expires?

From the Mythinkcar website:
【Car Diagnostic Tool Subscription Fee】

Per reset service/$49.95/year works for multi cars. Per software for one car model/$39.95/year, $70/year with full software.

You can select any of the manufacturer software in ThinkStore, and you can use them for free for one year.
  • Manufacturer Software Price for Each: $39.95/year
  • Reset Software Price for Each: $49.95/year
  • All Software Price ( All car software and All Reset Software+free update): $70.00 for 1 Years
What's the difference Reset vs Manufacturer.

Hey all. I wanted to mention I bought this android tablet last year, opened the box but never ended up using it as I have a Google pixel. If anyone is wanting a basic android device to use your Thinkdiag, I will sell it for $60 shipped free to anywhere in the lower 48 states:

put the gt3 back and decided to live with the message. transformative, really.
I see that you kept the GT3 profile on early 991.1 so I'm just wondering if you are still using and and if you'd had any issues. I have same early 991.1S and tried this and really liked the feel but I'm hesitant to leave it in place with the error it throws.

Thanks

My 2015 had been happy as a clam since I updated the steering to GT3, ~1 month ago. Mine did not have an error messages for the record.

yes, i still have it set. i suppressed the warning with the procedure in this thread but the steering feel is so much better i would leave it even if i couldn't.

i have no fear that this is anything other than an upgrade.
