Dear Khun Richard.
Let’s me discuss to our Head Technician and Service Agent for your case again because I don’t understand as well about the car,
I’m just be interpret between you and service agent and I will do my best and will hurry up to follow the case as soon as I can.
Or maybe I will ask our Head Technician and Khun Gary answer back to you for more information.
Sorry for this inconvenience.
