Hello All

Lovin my 'new to me' RX8 03 plate....she is in velocity red and called Scarlett.

Couple of issues that maybe y'all could help with please........

1. Today my visteon 41844 remote won't unlock the doors, but it will unlock the boot and will still lock the doors.

Can open the door with the actual key but then the hazards come on and a red light (car shaped with a key in it) flashes.

Do I need to reprogramme the remote...if so how? If not what?

2. The little disk showing the gears on top of the gear stick is missing, will I have to go to a dealer to order another or is there a cheaper option?

3. Two weeks ago an orange light (engine shape) came on on the dash. Car is running beautifully........what does this mean?

Thanks for reading, hope you can help
