Problem lowering suspension using vcds

[A8P]

Hi, hope someone may be able to help with this.

I invested in a Ross Tech VCDS. 1 reason among many was to lower my suspension. However on following the instructions for this I have not managed to get this to work. See link below.

I followed these instructions to the letter then test drove the car. Came back reconnected and then did it again but adding the mm values to the current values to lower it on each wheel.

Cut a long story short no matter what I did the values on each wheel measured manually were nothing like what we imputed and saved. And every time I go back to the vcds the values were just reset. But the car had changed when measured manually.



Am I doing something wrong?
