Service Descriptions
Comprehensive Audi oil and filter change using OEM-approved synthetic oil and filter. This service restores proper lubrication, protects turbochargers and timing components, and maintains long-term engine health.
Audi engines of all variety (e.g. TFSI, TDI, or performance S/RS variants) operate under high heat and pressure that quickly degrade engine oil. Regular oil service is essential to protect turbochargers, timing chains, and internal seals from wear and sludge buildup. Our service 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 cartridge or spin-on filter, and clean the housing for a proper seal. Fresh Audi-approved synthetic oil (VW 502/504/507 spec as required) is filled to the exact capacity and viscosity for your model. The drain plug and housing are tightened to specification, and the engine is run through warm-up cycles before rechecking for leaks. Finally, we reset the service reminder in Audi’s MMI system and confirm oil pressure and temperature stability. Regular service every 5,000 miles or 6–12 months ensures smooth performance and long-term reliability.
Service Milestones
Perform first oil change at 1,000 miles to remove break-in debris.
Repeat every 5,000 miles or 6–12 months to protect turbochargers and timing components.
In severe use (short trips, heavy stop-and-go, extreme heat/cold, towing), shorten interval to 3,000–4,000 miles.

Service Descriptions
Comprehensive Audi brake fluid flush using VW/Audi-approved DOT 4 or DOT 4 LV fluid. This service restores boiling point, protects ABS/ESC valves, and ensures consistent braking performance.
Audi braking systems rely on clean hydraulic fluid to deliver precise stopping power. Over time, brake fluid absorbs moisture, lowering its boiling point and risking internal corrosion in ABS pumps, master cylinders, and calipers. This can lead to brake fade, spongy pedal feel, or compromised safety. Our service includes a full inspection of the reservoir and fluid condition, complete evacuation of old fluid, and flushing with Audi-approved DOT 4 or DOT 4 LV fluid. Each wheel is bled in the correct factory sequence, and the ABS/ESC unit is cycled with ODIS diagnostics to ensure complete fluid exchange. We finish by verifying firm pedal feel and consistent braking response. Regular service every 20,000 miles or 2 years helps maintain confidence in all driving conditions.
Service Milestones
If service history is unknown, begin with a full flush to establish baseline fluid quality.
Every 2 years or 20,000 miles to maintain ABS/ESC performance.
For track driving, mountain roads, or humid climates, shorten interval to 12–18 months.
Flush if moisture test strip fails or fluid appears dark/contaminated.
Always flush after replacing calipers, lines, or master cylinder.
Possible Symptoms

Follow Audi’s factory bleed order for proper service.
Inspect hoses, lines, and unions for leaks or cracks during every flush.
What You'll Leave With
A detailed report confirming fluid type, bleed sequence, ABS cycling, and before/after condition. Includes photos at reservoir and bleeders, leak inspection notes, and the next recommended interval.
Service Descriptions
Comprehensive Audi engine air filter replacement using OEM-approved filters. A fresh filter restores clean airflow, protects turbochargers and sensors, and helps maintain fuel efficiency and performance.
Audi engines, whether TFSI, TDI, or high-performance S/RS models, require precise airflow for proper combustion. Over time, the air filter becomes clogged with dirt, dust, and pollen, restricting intake airflow. This can cause reduced fuel economy, sluggish performance, and added stress on turbochargers and MAF sensors. Our service begins with an inspection of the airbox and filter element. We replace the filter with an Audi-approved part that meets OEM specifications, ensuring a proper seal to keep unfiltered air out. The housing is cleaned of debris, and intake connections are checked for cracks or leaks. Finally, we reset the service interval in Audi’s MMI system if required. Regular replacement every 15,000–30,000 miles or 12–24 months keeps your engine breathing clean, efficient, and strong.
Service Milestones
Replace around 15,000–20,000 miles to establish a clean baseline.
Every 20,000–30,000 miles or 12–24 months to maintain efficiency.
In dusty, urban, or high-pollution areas, shorten interval to 10,000–15,000 miles.
Always replace after intake housing, turbo, or MAF sensor repairs to ensure clean airflow.
Possible Symptoms

Turbocharged engines are more sensitive to airflow restrictions. Having fresh filters is essential.
What You'll Leave With
A detailed report documenting filter condition, part numbers installed, inspection notes on the intake housing, and the next recommended interval. Includes before/after photos of the filter.
Service Descriptions
Comprehensive Audi cabin air filter replacement using OEM particle or activated charcoal microfilters. Fresh filters improve airflow, trap dust and pollen, and enhance interior comfort by keeping the cabin air clean.
Audi vehicles use advanced HVAC systems that rely on clean cabin air filters to provide fresh, filtered air and protect blower motors and evaporators from dust and debris. Over time, these filters become clogged with pollutants, pollen, and moisture, reducing airflow, straining the fan motor, and causing odors inside the vehicle. Our service includes inspection of the HVAC housing, replacement with an Audi-approved filter that meets OEM specifications, and cleaning of the housing to ensure a proper seal. Activated charcoal microfilters may be used for enhanced odor and pollutant absorption. Regular replacement every 15,000–20,000 miles or 12–24 months ensures clean cabin air, protects HVAC components, and supports a comfortable driving environment.
Service Milestones
Replace around 15,000 miles to establish clean baseline.
Every 15,000–20,000 miles or 12–24 months to maintain fresh cabin air.
In dusty or urban environments, shorten interval to 10,000–12,000 miles.
