Porsche Cayenne 955/957 (1st Generation)

20032010 · 955 · suv

First-gen Cayenne. 955 (2003-2007) and the 957 facelift (2008-2010). Engines from 3.2L V6 to twin-turbo 4.5L V8 (Turbo S). Shared platform with VW Touareg and (later) Audi Q7. Saved Porsche financially and bankrolled Cayman, Boxster, and modern 911 development.

Watch out: V8 cars: coolant pipes inside the engine valley are plastic — failure causes hidden coolant leaks and overheating. Aluminum-pipe retrofit is the standard fix. Air suspension compressor and accumulators wear with age. Both are expected expenses on a 15+ year-old V8 Cayenne.

Full clubhouse — owner Garage Lineage, common problems, year-by-year notes, and product picks — is on the build list.
