What happens: 🔌 Plug in cheap dongle 🚫 “Card not detected” 🔁 Wipers go crazy 💀 No start
This is a known issue with non-Renault approved dongles. The dongle has likely corrupted the communication. YouTube Video Script (60 seconds) Title: Renault Dongle
Still getting 'Card Not Detected'? The dongle may have corrupted the hands-free module. You’ll need a genuine Renault CLIP diagnostic tool to re-sync the UCH and injection computer.
Close up of a flashing red/green OBD dongle, then a Renault dashboard with warning lights.
Never re-insert that dongle. Bring your key cards and the dongle itself for inspection.
Why: Renault’s CAN bus expects specific timing . Cheap dongles send garbage data → UCH crashes.
Unplug the dongle immediately. Step 2: Lock and unlock the car with the key blade. Leave it for 10 minutes. Step 3: If the UCH (body computer) is frozen, disconnect the battery negative terminal for 15 minutes.
