Need advice please: Last service recorded by Jaguar - August 2020 - 25,000 (105,000/84months)

May 2022 - Oil service prior to acquisition

May 2023 - "Full service" by local independent

What is needed now and how often should plugs be replaced? 

Mileage: 38,100

Many thanks in advance for any suggestions.

Hi Andrew, the service regime on a Modern XK falls into 2 categories, A and B service options and are time or mileage dependent, whichever comes first. In the notes below it is time in months / mileage.

A Services: 12/15, 36/45, 60/75, 84/105, 108/135 and so on.

B Services: 24/30, 48/60, 72/90, 96/120, 120/150 and so on.

Some service items are time dependent and some are mileage dependent and it is quite difficult to be overly specific regarding a car that is not doing the mileage, but being serviced annually on the time element.

Spark plugs are listed to be renewed at the A Service for 105k miles.

Also at 105k miles, the Supercharger belt should be replaced - obviously only for the Supercharged cars.

At 150k miles, the front accessory belt should be renewed.

There is a caveat against the Service items above that these 3 items are specifically Mileage related and not defined by time.

Generally speaking, every annual Service should see the Renewal of the Oil and oil Filter, plus Renewal of the Pollen Filter. Every second Service, the B Service, then the Brake Fluid should be renewed.

Hope this helps.
