Review on 🚗 iCarsoft POR-II Porsche OBD-II Scanner Tool: Advanced Multi-systems ABS SRS Diagnostic Solution by Phil Kuebler

Uses POR-II to reset the "Service Now" warning that appears at ignition for an oil change on a 2008 Cayenne. The UI is slow and it's not entirely clear whether each item is checking, listing, or writing data - so it's important to read the manual before selecting an item. You sit and wait for the POR-II to go through a 30 minute procedure every time you make a mistake. It's not Durametric, but the POR-II can do a lot of things that a regular OBD scanner can't. Definitely worth it if you own more than one Porsche. One note - you cannot write to the ECU while the engine is running. You need to start the engine to power the OBD port and then just before doing the ECU write, turn off the engine but leave the car in the ACC position - that's a left click for Entry&Drive -Cars. After the process is complete, turn the key to the OFF position and then turn on the ignition.
