We are aware of a number of aftermarket companies offering modifications or alterations to your vehicle's specification. Whilst these can look an appealing way of changing an aspect of your car for a reasonable fee, these modifications (such as engine tuning, head unit alterations such as Apple Car Play or Android Auto) often modify the vehicle's software from the manufacturer's standard.

Invariably, these modifications will invalidate the Warranty on any components associated with the alterations, and you may be left to cover the cost of any repairs required. Many companies may promise that the modifications can not be detected by BMW diagnostic equipment, but this is not the case.

Please be advised that any changes to the vehicle specification may also affect your car's trade-in value, and any vehicles purchased on finance require prior authorisation from the finance company for any such alterations. If you have had your vehicle modified in any way, could you please advise your Service or Sales Advisor at your next visit to avoid any unnecessary issues arising as a result of any repairs required.

Should you have any questions please get in touch with our Aftersales Teams, they will be will be happy to assist.
