The second generation of the Cayenne (958) cemented it’s top selling place in the Porsche lineup with enhanced refinement and sophistication. Porsche Cayenne maintenance schedules remained relatively unchanged until the introduction of the Hybrid model. Typically, time elapsed is now exceeding mileage intervals for the early 958 models, so it’s important to understand what maintenance items should be addressed at specific intervals regardless of mileage recorded.
For inspection based maintenance on your Porsche Cayenne, you’ll need the experience and knowledge-based recommendations from a shop with specific Porsche expertise.
Porsche Cayenne Recommended Maintenance Intervals
To keep your second generation Porsche Cayenne healthy, we recommend you inspect the car and change the engine oil and filter annually or every 10K miles. The original Porsche Cayenne 958 maintenance schedule (included below) called for a minor service at 20K or two years and a major service at 4 year or 40K mile intervals. Additional maintenance items are also required at the six year and 16 year interval, as shown below. The original service schedule called for air filter replacement every 80K miles – we recommend you shorten this interval significantly.
Many people become confused by Porsche maintenance schedules. The intervals and maintenance items are cumulative – so for clarity, a 4 year service includes all the maintenance items recommended at the 4 year interval, plus all maintenance items from the 2 year and annual maintenance interval as well.
Porsche Cayenne Transmission Maintenance
The original Porsche schedule for transmission fluid change was almost neglected and posted as a foot note on the documentation. The fluid was supposed to be “lifetime” and it was assumed it didn’t need to be replaced regularly. In practice, many Porsche Cayenne owners have experienced degraded performance or failure of the transmission because of this. As you can see below, we recommend you service the transmission fluid and filter at 80K mile or 8 year intervals at a minimum.
Safety and Maintenance Inspection
Every annual service should include a rigorous safety and maintenance inspection. It’s essential this is carried out by a skilled technician who knows the likely wear characteristics of your Porsche and can identify issues of concern at an early stage. A good inspection will help to identify those maintenance items that have been influenced by local environmental conditions.
Some maintenance items are described as “lifetime,” such as coolant, for example. It’s important during the inspection to discover the health of these “lifetime” items. If you need cold weather protection from your coolant, you’ll find the “lifetime” is considerably shorter than you might expect! Identifying mechanical problems at an early stage allows planning and budgeting for the necessary work.
