A DUI stays permanently on your driving record in California... there is no "diversion program" that relates to a DUI. Perhaps you are doing a diversion program in order to avoid being convicted of a drug offense. The completion of such a drug diversion program will result the drug offense being dismissed, but not the DUI.
The DUI stays on your record forever. It will last 10 years on the DMV record. There is no diversion for a DUI in California.
