A Success Story

Porsche Cayanne 2011, Restored Performance


At Sauri Classics, every project is an opportunity to showcase our passion for Porsche vehicles and our ability to solve even the most challenging problems. Today, we’re excited to share a story that shows the impact of a professional, detailed, and dedicated approach.


The Challenge

A few months ago, a customer reached out with a persistent issue in their 2011 Porsche Cayenne. The vehicle was having recurring power loss and performance failures, significantly affecting its reliability. Despite multiple visits to official service centers and numerous repairs and part replacements, the problem kept returning, causing frustration.


A Complex Diagnosis with Multiple Variables

When this Porsche Cayenne came to our workshop, we quickly realized we were facing a technically complex challenge. Intermittent nature of the issues and the lack of clear diagnostic codes from the vehicle’s systems made identifying the root cause difficult.


At Sauri Classics, we understand that success lies in details. That’s why our team initiated a comprehensive review process, which included:


  1. Inspection of the electrical system and wiring: We analyzed each component related to energy distribution, searching for faulty connections, damaged wiring, or internal anomalies.
  2. Testing the Control Unit: We conducted an in depth analysis of the contro unit's behavior, ensuring it could accurately process engine signals.
  3. Temperature testing: We evaluated the engine’s performance under various thermal conditions to rule out issues related to overheating or fluctuations.
  4. Fluid analysis: We inspected all vehicle fluids, including fuel, oil, and coolant, for contaminants or irregularities that might affect engine performance.


The Solution: Identifying and Resolving the Issue

After hours of analysis and numerous cross checks, our technicians identified the root cause: a failure in the injectors caused by a short circuit in the electrical system. This particular fault was especially hard to detect, as it prevented the system from generating visible error codes in standard diagnostics.


Thanks to the expertise and technical knowledge of our specialized team at Sauri Classics, we not only detected this critical issue but implemented a definitive solution, ensuring the 2011 Porsche Cayenne recovered its optimal performance.


The Result: A Happy Customer and a Like New Vehicle

A few months after the repair, we followed up with our customer to learn about their experience. We’re pleased to report that the Cayenne 2011 not only exceeded expectations but now delivers impeccable performance, even in demanding conditions.


Our Commitment: More Than a Repair, an Experience

This success story is just one example of the high quality work we deliver as specialists in Porsche vehicles. It also reflects our philosophy: solving problems where others cannot.
