Audi Repair & Diagnostics in Mount Prospect, IL

German Auto, LLC is an independent Audi specialist in Mount Prospect, Illinois, providing maintenance, diagnostics and repair. Audi vehicles pair turbocharged and supercharged engines with Quattro all-wheel drive, several transmission designs and extensive electronics, including the MMI system. Servicing them well means understanding how those systems work together, and testing before replacing parts.

Advanced Audi Diagnostics

We diagnose check-engine and EPC warnings, misfires, oil consumption and oil leaks, cooling-system faults, turbo and boost problems, electrical faults and battery drains, CAN-network communication issues, ABS and stability-control warnings, transmission electronics, Quattro faults, MMI and module problems, and emissions faults. A code tells us where to start; live data and circuit testing tell us what failed. Our diagnostic process →

Audi Engine Repair

Audi's 2.0T, 3.0T and other supported engines have well-documented service needs. We repair oil leaks, PCV and oil-separator faults, cooling-system problems, water pumps and thermostats, misfires and ignition faults, fuel-system issues, turbocharger problems, intake and boost leaks, timing faults, engine mounts, and sensor and actuator failures. Oil-consumption concerns are diagnosed properly rather than assumed. Engine services →

Audi Cooling Systems

Cooling faults are among the most common Audi repairs. We service water pumps and thermostats, coolant leaks, radiators, hoses, expansion tanks, cooling fans and the electronic cooling controls that manage engine temperature on modern Audi engines.
