Founded in 1994, South Bay Autohaus in Chula Vista is an independent Mercedes-Benz sales, parts, and service facility on Trousdale Drive just off Highway 54. Factory-trained technicians use Mercedes-Benz XENTRY diagnostic systems and Star Diagnosis multiplexers for fault-code interrogation across every series from the W124 to the W213, with the same OE-spec tire and wheel fitments available at Evans Tire. The in-house parts department stocks genuine Mercedes-Benz oil filters, brake pads, and transmission fluid for same-day turnaround on scheduled A-Service and B-Service intervals. South Bay Autohaus services new Mercedes-Benz vehicles still under factory warranty, performing manufacturer-required maintenance without voiding coverage under federal Magnuson-Moss protections. Post-collision mechanical restoration pairs Autohaus drivetrain and suspension work with the structural and refinish repairs at Caliber Collision. The shop's highest-complexity work includes 722.9 seven-speed automatic transmission valve-body replacements and M278 biturbo V-8 charge-air-cooler overhauls using factory torque sequences.
