The ABS module in the Porsche Boxster (986)

The 1997-2004 Porsche Boxster (986) uses this ABS unit: Bosch Bosch 5.7 (per a rebuilder); ABS/PSM module 996 355 955 xx. source ↗ The same listing covers the Boxster (986) and 911 (996) Carrera / Turbo. On our bench that puts it in the Bosch ABS / ESP 5.7 family, alongside 4 other vehicle lines on this site.

Its ABS module appears under 10 part numbers in the sources we checked, starting with 996-355-955-GX (A rebuilder's OEM number, ABS/PSM module, 1997-2004 Boxster and 1999-2004 911). source ↗ Different numbers usually separate model years, drivetrains and option packages — match the number on your own module label rather than the year alone. The control unit is mounted on the valve block. On many units it unbolts, so the brake lines stay on — send us a photo if you are not sure.
