2014 Porsche Cayenne Diesel – Preventive Maintenance Tips
Location: La Mesa, CA
Project Type: Residential
Duration: A few hours

Project Overview:
At Euro Auto Tech & Smog, we recently performed a Service A on a 2014 Porsche Cayenne Diesel—an impressive SUV known for its torque and performance. But keeping it running strong takes more than just the occasional oil change.

Common Issues in the 2014 Cayenne Diesel:
Many owners overlook key components that can lead to major problems if ignored:

• Clogged EGR coolers
• Failed NOx sensors
• Coolant leaks

Neglecting these can trigger limp mode, increase emissions, and reduce performance.

Our Preventive Maintenance Tips:
To keep your diesel Porsche running at its best, we recommend:

• Fuel Filter Replacement: Every 10–15k miles
• Oil Service: Every 5–7k miles (don’t fall for the 10k+ mile myth)
• Diesel System Cleaning: Regular intervals
• Transfer Case Inspection: Especially important at 80k+ miles

Why This Matters:

• Improved throttle response
• Better fuel economy
• Fewer warning lights and unexpected repairs

Products Used:

• 2014 Porsche Cayenne
• Liquid Moly Oils
• OEM Oil Filters
• Coolant
• Transfer Case Fluid

Estimated Costs:

• Service A (Oil, Filter, Inspection): $250–$350
• EGR/Intake Cleaning: $700+
• Transfer Case Fluid Service: $150–$250
