Which tool is good to disable Auto start/stop on 2019 Porsche Cayenne?

Both Launch X431 CRP919E BT/CRP919X BT diagnostic scanner and Autel MaxiCOM MK906BT can do this perfectly. Other Autel Maxisys tablets also support this function as well. MK906 is cheaper.

1.Launch CRP919EBT Serial disable Auto start/stop on 2019 Porsche Cayenne Turbo

You can set the start/stop to activate to last setting on restart via X431. This eliminates the need to press the button on every start up.

We got stop-start disabled with a CRP919E BT scanner or a none-Bluetooth version CRP919E!

Need to go into “SYSTEM SELECTION” from the diagnostic report.

Menu function path:

Porsche>> Cayenne 9YA>> System Selection>> DME (Digital Engine Electronics)>> Coding value- Block07 (1)-Start_stop>> Write Code

Enter the keyword

Coding is successful.

2.Autel MK906BT disable start/stop feature on 2019 Porsche Cayenne S

Auto start stop Deactivation Procedure:

1. Selected Porsche
2. Use Auto-Bin to automatically process VIN (Needs to have key in second position, with engine off)
3. Diagnosis
4. Auto-Scan
5. DME (Engine Electronics)
6. Coding
7. Coding without rules
8. Coding
9. Modify values below
10. Write values
11. Exit to home screen

After 8, and there was some waiting to do, I was presented with a table of fields.

There were two important fields that needed to change.

Original Field Names Values

• “Block07 start stop” “Present”
• “Block 08 start stop last mode” “Default On”

New Field Names Values

“Block07 start stop” “Not available/coding…”

“Block 08 start stop last mode” “Last Mode”

I first set the fields “Block 08 start stop lastmode” to “Last Mode” and it gave me an error message saying to check on conditions when I tried to write it.

Then, I set the “Block07 start stop” to “Not available/coding…” and it was successful when I tried to write it down.

I used to have the “Start/Stop” icon on my main home screen to be able to manually disable it, but after the updates, it is not there anymore, and the “Start/Stop” feature is not active any more.

It worked for me, but you are on your own, since too many things can happen.

I really despise the auto “Start/Stop” feature, to the point that I will not buy another Porsche if that feature is not remembered, or disabled, after a restart.

Start/Stop feature disable and removed from main screen

I also coded windows/sunroof open and close with key fob, and Autel MK906BT disabled some of the annoying chimes as well.
