What's the issue when the gear indicator light flashes on a Golf 6?

[ElijahFitz]

It is likely that there is a gear malfunction, triggering a self-protection measure. It is recommended to restart the vehicle. If the issue persists, you should take it to a 4S shop or repair shop for inspection tomorrow. Other possible causes: There may be a malfunction or poor contact with the gear sensor; there could be an issue with the transmission; or the light wiring may have poor contact. Solutions for a flashing gear indicator light: Open the engine compartment and check if the wiring is aged or if rodents have damaged the wires; try shifting into each gear to see if it engages normally—if it does, the gear switch might not be properly installed; there could be an issue with the wiring from the gear switch to the computer, such as looseness or rust; problems with the transmission or battery can also cause the gear indicator light to flash. Remove the gear switch, disassemble it, and check if the copper contacts inside have excessive grease. Clean off the grease and reinstall the gear switch.
