If your aftermarket tool “used to do it” and now it can’t, it’s probably not the update.
It’s the car.
More brands are moving everyday functions behind security gateways, so the menu still shows the option, but the vehicle won’t authorise it.
That’s why you can still:
✅ read and clear basic OBD faults
✅ view live data
But you can’t:
🚫 run AdBlue resets
🚫 complete EGR functions
🚫 do protected calibrations
When you’re comparing tools, don’t ask “what does it cover?” first. Ask “what does it unlock?” and whether the unlock is included, pay-per-use, or not supported.
We filmed a short walkthrough on how to spot a gateway block, and how to future-proof your setup.
Comment “GATEWAY” and we’ll send it directly.
