My S3 is 4 years old and they said it should be done evry 2-3 years to ensure maximum efficiency and avoid failures and reduce excess load on the system.
I have always replaced my cars after 2-3 years and never had this done in the past.
Anyone else had this done or have any advice if its really needed ?
