Thank you for your patience on the matter. We have asked our engineering team to re check based on today’s information I collected from your vehicle noting your remarks about the issue getting progressively more pronounced. From all previous information this should have been addressed with the most recent firmware update so I will be chasing this up with them.
Again I would like to thank you and extend our apologies for any inconvenience caused. Please feel free to contact us should you require any further assistance or have any other questions.
Kind Regards,
