Welcome to the forum Emmax_B,

I've moved your question from Jaguar Forums Feedback & Suggestion Centre to S-Type forum. Members here with the same model will be able to help.

Please follow this link New Member Area - Intro a MUST - Jaguar Forums - Jaguar Enthusiasts Forum to the New Member Area - Intro a MUST forum and post some information about yourself and your vehicle for all members to see. In return you'll get a proper welcome and some useful advice about posting to the forum.

Use the OBD port to determine what DTCs are stored and post them here. DTCs are typically in the format of P0301, for example.
