JMG Maintenance Articles

In this section of the articles corner of the website you will find interesting and hopefully informative technical articles about all kinds of things Porsche, automotive and technology based, which are relevant to Porsche ownership and repair.

As the technical advisor to Porsche clubs, associations and publications around the world, Jon often writes articles not only for consumption by the general public, but also by independent and main dealer (OPC) Porsche technicians wishing to expand their knowledge.

The main purpose of this section is to assist in educating customers so that they may understand their Porsche in greater detail or to understand the diagnostic and repair processes we may be recommending for their Porsche.

Should there be an article you would like to see featured here, please feel free to contact us via our contact page, where we may be able to schedule that article to feature here in the near future.
