This factory manual for the 1998 Porsche Boxster is built around the 2.5L flat-six (engine code VIN A) as Porsche configured it that year, so the compression figures, torque values and diagnostic steps inside are the ones written for this specific engine and trim rather than a generic Boxster reference.

Known issues on the 1998 Boxster. Four recalls are on federal record for this model year. The first covers the Tiptronic automatic transmission: an incorrectly adjusted key-lock cable can let the selector lever move out of Park without the parking brake set, so the car is not secured against rolling away. The second covers an aftermarket child-seat air bag deactivation kit sold for Boxster and 911 models, whose contact buckle fails to deactivate the air bag, risking severe injury to a child occupant if the bag deploys in a crash. The third and fourth cover two separate aftermarket corner and bumper lamp assemblies, from SaberSport and from Dope, Inc., that were sold without the amber side reflectors required by federal lighting standards, reducing visibility to other drivers. Owners have filed 34 complaints for the year, and no technical service bulletins are logged. The factory diagnostic and repair procedures behind each of those systems are here.
Whether you're inspecting the shift interlock, checking a lighting installation, or working through a routine service interval, it keeps you on the OEM procedure and the correct specification for your specific 1998 Boxster.
