why not just post your original file and comment what youve tried and ask for help its mostlily easier then youd think...
Ok, here we go:
The DTC error is #12A2. I found the error, but it's a little different of a comparsion OLS I have from a Touareg (yes, it's suppose to be the same).
Attached, the OLS of touareg VR6 MED9.1, the original file and a OLS project I started. I assumed that this specific DTC lies at address 1DC354, but, as I'm not 100% sure, I'm asking for help.
