When your Porsche’s engine hits its scheduled service interval or begins to show early signs of wear, like muted throttle response, slight oil seepage, or rough idle, then our technicians at Bavarian Auto Repair perform a meticulous maintenance regimen designed to preserve performance and longevity. We start by swapping out the old oil for the exact synthetic grade your model requires and fitting a new OEM filter, then inspect spark plugs, ignition coils, air and fuel filters for wear or contamination. Belts and hoses are examined for cracks and proper tension, valve clearances and timing-chain tension are measured against factory benchmarks, and thermal imaging confirms even heat distribution across the cylinders. After topping off all fluids to manufacturer-specified levels, we carry out a final road-test to verify smooth idle, crisp acceleration, and leak-free operation. You’ll receive before-and-after photos, a clear service summary, and an upfront estimate so you know exactly where your investment goes.

Service Descriptions
Comprehensive Porsche oil and filter change using OEM-approved synthetic oil and filter. This service restores proper lubrication, protects turbochargers and timing components, and ensures long-term engine health.
Porsche engines, including flat-six, V8, and turbocharged variants operate under extreme heat and stress that accelerate oil degradation. Routine oil service is critical to protect turbochargers, timing chains, and internal seals from sludge, varnish, and premature wear. Our process begins with a full inspection of the oil pan, drain plug, and filter housing for leaks. We then drain the old oil, replace the OEM filter, and clean the housing for a proper seal. Fresh Porsche-approved synthetic oil (meeting A40, C30, or Mobil 1 factory specifications depending on model) is filled to exact capacity and viscosity. The drain plug and housing are torqued to spec, and the engine is warmed to confirm oil pressure and circulation. Finally, we reset service reminders in the PCM system and document the service. Regular oil changes every 5,000 miles or 6–12 months preserve engine longevity and peak performance.
Service Milestones
Perform first oil change at 1,000 miles to remove break-in debris.
Repeat every 5,000 miles or 6–12 months for optimal engine protection.
In severe use (track driving, short trips, extreme heat), shorten interval to 3,000–4,000 miles.

Service Descriptions
Porsche brake fluid flush restores safe braking response by replacing old, moisture-contaminated fluid with OEM-approved DOT 4 or Porsche-specified fluid. This prevents brake fade, corrosion, and ABS/PSM issues.
Brake fluid absorbs moisture over time, reducing its boiling point and increasing the risk of vapor lock or brake fade under heavy braking. For Porsche vehicles, especially high-performance 911, Cayman, Boxster, Panamera, and Cayenne models, maintaining fresh brake fluid is critical for both safety and track performance. During this service, our technicians flush the hydraulic system using Porsche-approved DOT 4 fluid (or high-temperature motorsport fluid if specified), bleed each caliper using PIWIS diagnostic-assisted procedures, and inspect lines, hoses, and calipers for leaks or wear. A road test verifies pedal feel and braking performance. Regular brake fluid replacement every 20,000 miles or 24 months ensures strong pedal response, protects ABS/PSM modules, and preserves stopping power.
Service Milestones
Perform first brake fluid flush at 20,000 miles or 2 years if history is unknown.
Flush every 20,000 miles or 24 months for safety.
In track, mountain, or severe conditions, shorten to 10,000–15,000 miles or 12–18 months.

Service Descriptions
Porsche engine air filter replacement ensures clean airflow for maximum performance. Our technicians install OEM-approved filters, inspect the housing, and remove debris to protect your engine and maintain power.
The engine air filter prevents dirt, dust, and debris from entering your Porsche’s intake system. Over time, filters clog and restrict airflow, leading to reduced performance, lower fuel efficiency, and increased engine wear. High-performance Porsche engines, such as flat-six or turbocharged variants, are particularly sensitive to airflow restrictions. During this service, we replace the air filter with a Porsche-approved part, inspect the housing for leaks or cracks, and document the condition of the removed filter. For vehicles driven in dusty or high-performance environments, earlier replacement may be necessary. This preventive service helps maintain horsepower, throttle response, and long-term reliability.
Service Milestones
Replace first air filter around 15,000–20,000 miles or 12–18 months.
Replace every 20,000–30,000 miles or 18–24 months.
In dusty climates or frequent high-performance driving, shorten interval to 10,000–15,000 miles.
Possible Symptoms
Severity
Medium
Description
Throttle response feels sluggish due to restricted airflow.
Action
Replace air filter to restore performance.
Severity
Medium
Description
Increased fuel consumption from reduced efficiency.
Action
Install a new OEM filter to improve efficiency.
Severity
High
Description

Check air filter condition during every oil change.
Replace cabin air filter at the same time for balanced maintenance.
Maintain records with photos to support warranty and resale value.
What You'll Leave With
A detailed report with photos of old vs. new filter, inspection notes on the housing and ductwork, confirmation of OEM filter installation, and documentation of the next recommended interval.
Service Descriptions
Porsche cabin air filter replacement improves interior air quality and HVAC performance. Our technicians install OEM-approved filters, inspect the housing, and confirm proper airflow for a clean, comfortable cabin.
The cabin air filter in your Porsche traps dust, pollen, and pollutants before they enter the HVAC system. Over time, the filter clogs and restricts airflow, straining the blower motor and allowing odors or allergens into the cabin. In dusty or urban environments, the filter may clog faster and require earlier replacement. During this service, we replace the filter with a Porsche-approved component, clean and inspect the housing, and confirm HVAC performance. This preventive maintenance keeps your interior fresh, reduces allergens, protects the HVAC system, and maintains the luxury comfort Porsche drivers expect.
Service Milestones
Replace cabin filter at 15,000–20,000 miles or 12–24 months.
Replace annually under normal use.
In dusty or urban environments, shorten interval to 10,000–12,000 miles.
Possible Symptoms

Combine cabin filter replacement with A/C service for efficiency.
Detailed records support warranty and resale value.
What You'll Leave With
A detailed report with photos of old vs. new filter, inspection notes of housing and seals, confirmation of OEM filter installation, and documentation of the next recommended interval.

This is our new favorite place to go to for our car maintenance. They are are really fast and helped us when we got our used car by looking it over to make sure everything was good
- Google ReviewI have been taking my Porsche here for awhile. I can’t find a better repair shop for my car, these guys are 100% the best in town.
- Google ReviewThe team in Boerne handled the 20K mile service on my 2023 Porsche 911 Carrera T with care. The pricing was fair, and the staff was incredibly friendly and personable. Derek and his crew did an excellent job taking care of both me and my car. He welcomed follow-up questions and responded quickly to ensure I was completely satisfied. I also spoke with the technician about the car once the service was finished. I’m definitely planning to return for my 30K mile service or whatever’s due next year. The snacks were pretty good while I waited for the service—really good stuff. Thanks! :-)
