Here we share a simple procedure to lower the ride height on air suspension Porsche (in this case Macans) using the height calibration procedure.

The height calibration method introduces unnecessary risks into the process, but now there is another method to accomplish the same thing using coding.
This procedure was tested successfully, and the good thing is that since you are coding, you can safely execute the procedure with PIWIS, with Launch X431 and with Autel/Otofix (If use OTOFIX, only OTOFIX D1 MAX and EvoScan Ultra can do Porsche online coding).
Started by re-doing a height calibration to return my Macan normal height, before attempting new process. If you want to use this procedure and have lowered your Macan using height calibration offset, you need to redo the calibration to return the Macan to normal height, then execute this procedure.
PROCEDURE:
1. Select Level Control/PASM in PIWIS, X431 or Autel/Otofix (In PIWIS, you need to change mode to Engineering before proceeding).
2. Select Coding without Rules
a. In PIWIS, you need to select Coding tab, then Coding without rules
b. In X431, you need to select Coding Brush
c. In Autel/Otofix, select Coding, then Coding without rules
3. Then you will have to select the following:
a. In PIWIS, select Korrekturwerte
b. In X431 and Autel/Otofix, select Correction Values
You’ll see the following screen…
NOTE: TAKE A PHOTO OF ALL YOUR ORIGINAL VALUES FOR FUTURE USE IN CASE YOU WANT TO GO BACK TO STOCK
PIWIS (the last 4 fields)… with original values
Otofix/Autel with corrected values:
4. Enter the value corresponding to the amount you want to lower as follows: NEW VALUE = ORIGINAL VALUE – LOWERING VALUE.
If you want to lower the car by 25mm, then you take all original values and subtract 25mm, enter corresponding values in the fields and press WRITE.
You can measure all wheels and introduce adjustment values as necessary.
The good thing about this procedure is that because is just coding, then is safe to do with PIWIS, Launch X431 and Autel/Otofix. It also avoids all the complications of entering the wrong values during calibration.
