ECU Tune and Vault code
I had my DPF removed on a D3 5pot, about 3 years ago, due to it going bad.
So software DPF removal was done, and with that I had a tune done, as per my own specs. Did not want to go over the max nm allowed for the gearbox.
Now my question is, seeing that when a tune is done you get the errors:
CEM-U030100 - Software incompatinility with ECM/PCM
ECM-U032700 - Software incompatibility with vehicle security control module.
Will these fault codes influence the tune? As they do go from yellow warning to red in vida.
