● The 12 volt batteries, 48 volt batteries, any batteries used in mild hybrid vehicles and the high
voltage batteries used in hybrid vehicles are warranted against all defects in materials and
workmanship for 3 years from the date of handover to the first owner, or up to 60,000 miles,
whichever comes first.
Warranty against Battery Energy Content Degradation
...
● A gradual reduction in battery energy content over time is a normal feature of high voltage
battery and does not constitute a warrantable defect. However, high voltage batteries in
BEVs and PHEVs are warranted against excessive loss of net battery energy content as
detailed below. No degradation warranty exists for 12 volt batteries, 48 volt batteries, or any
batteries used in mild hybrid vehicle.
The repair will bring the performance of the high voltage battery back to the
following state, depending on the mileage / age of the vehicle at the time of
diagnosis:
■ Up to a maximum of 40,000 miles or three years after first registration
(whichever comes first), the energy content of the high voltage battery will
be repaired so that it measures a minimum of 78% of the starting value.
■ Up to a maximum of 60,000 miles or five years after first registration
(whichever comes first), the energy content of the high voltage battery will
be repaired so that it measures 74% of the starting value.
■ Up to a maximum of 100,000 miles or eight years after first registration
(whichever comes first), the energy content of the high voltage battery will
be repaired so that it measures 70% of the starting value.
...
For PHEVs, the battery energy content degradation warranty lasts for up to 5 years or up to
100,000 miles, whichever comes first, from the date of handover to first customer (or date of
first registration, whichever comes sooner) for the first vehicle owner only. This warranty is
not capable of assignment or transfer to subsequent vehicle owners. Where the battery
energy content of the high voltage battery is measured by a Volkswagen authorised repairer
and is found to be less than 70% during the warranty period, then it will be replaced or
repaired so that it measures a minimum of 70% of the starting value, or replaced under
warranty subject to the following:
