Specialists In Porsche Service for the Phoenix Area
Finding a mechanic who truly understands the intricacies of German engineering can be difficult. In a sprawling metropolis like ours, many shops claim to handle European cars, but few possess the specific factory training required to properly maintain a Porsche.
At McIlvain Motors, we are more than just a repair shop; we are enthusiast-driven specialists. Located centrally in Tempe, we serve as the go-to Porsche Mechanic in Phoenix for drivers who demand dealership-quality care without the dealership premium. From vintage air-cooled classics to the modern water-cooled 911 and Macan, your vehicle is in expert hands.
The Difference Between a Generalist and a Specialist
Modern Porsches require proprietary tools and specialized knowledge. A general mechanic might be able to change your oil, but they often lack the depth of knowledge to diagnose complex issues like PDK transmission faults or air-suspension failures.
As a dedicated Porsche Mechanic in Phoenix, we bridge that gap. We invest in the same technology used by the factory to ensure your car is treated exactly as the engineers in Stuttgart intended.
1. Factory-Trained Expertise
Our founder, Scott McIlvain, is not just an experienced technician; he is a graduate of the elite Porsche Technology Apprentice Program (PTAP).
- Select Company: Scott was one of only a handful of technicians nationwide selected for this intensive factory training in Atlanta.
- Deep Knowledge: This training covers everything from engine theory to complex electronics, ensuring we don’t just “swap parts”—we understand how the systems work together.
- PCA Involvement: Scott is a former Technical Chair and Chief Driving Instructor for the Arizona Region of the Porsche Club of America (PCA). When you leave your car with us, it is being serviced by a true brand authority.
2. Dealer-Level Diagnostics (PIWIS)
We utilize the Porsche Integrated Workshop Information System (PIWIS). This is the official factory diagnostic tool that allows us to:
- Read and interpret detailed fault codes that generic scanners miss.
- Code and program new control modules.
- Perform precise calibrations on systems like the PDK transmission and air suspension.
Our Specialized Porsche Services
We cover the full spectrum of maintenance and repair, but we are best known for solving the specific issues that plague these vehicles in the Arizona climate.
IMS Bearing Solutions
For owners of the 996 911 and 986 Boxster, the Intermediate Shaft (IMS) bearing is a critical concern. We offer proven IMS Retrofit services to prevent catastrophic engine failure, giving you peace of mind every time you turn the key.
Coolant System Upgrades
The Phoenix heat is brutal on plastic cooling components. We specialize in “pinning” coolant lines for GT engines (preventing sudden coolant loss on track or street) and upgrading plastic coolant pipes to aluminum on Cayenne and Panamera models to prevent cracking.
PDK Transmission Service
Many shops will tell you a PDK transmission is “non-serviceable” and must be replaced if it fails. As a specialized Porsche Mechanic in Phoenix, we can often repair specific components within the transmission or perform fluid services that extend its life, saving you thousands of dollars over a full replacement.

Conveniently Serving the Entire Valley
While our shop is located in Tempe, our reputation attracts drivers from all over the Valley. We are the preferred alternative for owners seeking a Porsche Mechanic in Phoenix, Scottsdale, Chandler, and Mesa.
- Honest Pricing: We offer the lowest labor rates among qualified independent Porsche shops in the state.
- Warranty: We stand behind our craftsmanship with a 2-Year / 24,000-Mile Warranty on services and repairs.
- Personal Touch: You speak directly with experts who know your car, not a service advisor reading from a script.
