Hi and welcome. Unfortunately Jaguar have removed access to build sheets for unpaid subscriptions in Topix. I don't know whether this is by design or a technical issue or whether by having a subscription the feature returns. Sorry.
If you have the VIN (I can get the VIN from a reg if you need it) then you could sign up and purchase access to Topix. Prices for a single model start from £25 an hour, up to £1000 for the entire year.
