Cayenne Maintenance & Repair Articles
2003 - 2007 (955 series)
2008 - 2010 (957 series)
2011 - 2018 (958 series)

For 2011, Porsche introduced an all-new Cayenne model.  Internally, Porsche refers to this model as the “958” series.  As with most models of vehicles nowadays, a “facelift” typically occurs midway through the life cycle of the model.   The 958.1 is from 2011-2014, with the 958.2 from 2015-2018.   The Cayenne continues to be a success story for Porsche with overall sales increasing significantly to 300,000+ for the 958.1 model alone.  The sleek new design of the 958 series looks smaller than the outgoing 957 Cayenne produced from 2003-2010, however it is actually 5cm (2 inches) longer, and with a wheelbase that stretches out an additional 4cm (1.5 inches).   The biggest news for the 2011-2018 Cayenne is it’s weight loss.   With almost 180kg (400lbs) less weight to haul around, and engines with more power and an 8 speed automatic transmission, you can expect increased all around performance and improved fuel economy.   The 958.1 (2011-2014) is available with 6 cylinder engines (Gas, Diesel, or Hybrid power), or a 4.8 litre 8 cylinder with or without turbo’s.   For the facelift model 958.2 (2015-2018), the Cayenne S dropped the 8 cylinder non-turbo engine in favour of the new Porsche engineered 3.6 litre V6 twin turbo, also found in the Macan.  All engines have proven to be excellent performers.  As with maintaining any vehicle, Riegel Tuning highly recommends an Oil Service and Riegel Inspection report every 8,000 km’s.  We only use Porsche Warranty-Approved parts such as oil, oil filter, air filter, and any other items recommended for your Cayenne’s service intervals.  See below for maintenance, repair and pre-purchase inpsection tips for this series of Cayenne:

• Check for outstanding recalls (we will do this for you) – Example: NHTSA Campaign Number 17V368000, Camshaft Controllers may loosen and fail inside the engine.  Up to 17,000 Porsche vehicles affected, including: 2011 Cayenne S and 2011 Cayenne Turbo
•  Transfer Case service.  We highly recommend transfer case fluid changes every 50,000 km’s.   It is cheap insurance against the cost of transfer case failure and replacement.   Transfer case issues are often misdiagnosed as a transmission or engine hesitation.   The issue is most noticeable as a hesitation when gently accelerating from 1st gear, and into 2nd, and 3rd gear
• Coolant Leaks are not as common on the 2011-2018 Cayenne as compared to the previous model, however, close inspection (often with a bore scope camera) may reveal sweating or existing leaks.   The glued in fitting at the rear of the engine connects the cooling bridge between the cylinder heads on early 2011 Cayenne’s with the V8 engine.    Additionally 2011-2014 V8 engines may have a failure where the two larger coolant pipes at the front of the engine are glued in to the thermostat housing.  The updated “bolt-in” style pipes are fairly inexpensive, but labour-intensive to install.   2015-2018 V8 Cayenne engines use the updated style pipes
• Water leaks inside the cabin of the Cayenne can be avoided with regular cleaning of the Cowl drains, along with removal/cleaning/reinstall of the drain inside the vehicle at the HVAC box
• Cayenne models with the V6 twin turbo require close inspection of the timing cover at the front of the engine for oil leaks and sweating.  If your Cayenne still has factory, extended, or aftermarket warranty, have use provide you with a detailed inspection report to avoid future costly repairs
• All Cayenne’s from 2011-2018 have Direct Injection, and experience varying degrees of carbon build-up on the intake valves and the intact tract.   This is oftern 
• If the vehicle is over 120,000 km’s without Service History, we recommend close inspection or replacement of the Water pump + thermostat
• Brake Pads and Rotors are a common maintenance item on Porsche Cayenne’s.  Front brakes often last 50-80,000 km’s, and rear brakes 80,000+ km’s.  Riegel provides an accurate brake measurement including pictures and/or video on our Riegel Service Inspection Report.  Trust the experts at Riegel for an accurate brake measurement should you Brake Light come on
