Bridging the Gap Between Mechanics &Computer-Level Diagnostics
Modern vehicles are high-performance computing systems on wheels. We deliver main-dealer diagnostic accuracy and mechanical execution without the dealer prices.
Our Mission: Engineering Root-Cause Diagnostics
Standard garages frequently use code readers and simply swap components hoping to resolve issues, causing customers bloated diagnostic costs and repeated visits.
At S&R Engine & Diagnostics, we implement a strict scientific method. We analyze communication signals, verify physical parameters using digital oscilloscopes, and trace current drops across wiring looms. We change parts only when we have direct physical proof of component failure.
Dealer-Level Diagnostic Infrastructure
We invest heavily in official main-dealer diagnostic channels including BMW ISTA, Mercedes XENTRY, Audi/VW ODIS, and Ford IDS. This allows us to flash ECU firmware, register batteries, and configure modules identically to the main dealership.
Hassle-Free Video Proof Reports
Transparency is the foundation of S&R. If we discover a faulty wiring loom, corroded sensor, or mechanical wear, we record a high-definition video of the measurement parameters on our scopes and email it to you before performing any repairs.
IMI Certified Diagnostics Masters
Our technicians hold advanced Institute of the Motor Industry (IMI) certifications in vehicle diagnostics and high-voltage hybrid/EV system sweeps. We analyze electrical telemetry using logical engineering, not guesswork.
12-Month/12,000-Mile Guarantee
Every replacement sensor, harness section, module, or mechanical item we install is fully covered under our parts and labor guarantee. We use exclusively genuine OEM or matching high-grade components.
Our Diagnostic Lab Equipment
Advanced software telemetry diagnostics requires specialized hardware tools. Here is what we use daily on client vehicles:
Digital Oscilloscopes
PicoScope telemetry equipment to capture signals directly at the wiring pins, measuring microsecond-level voltage variations.
Diagnostic Smoke Testers
Pinpoints high-pressure air leaks inside intake systems, turbochargers, vacuums, and DPF exhaust routes.
Factory Key Programming
Authenticates keys directly to immobilizer modules (EWS/CAS, EIS) using secure programming bridges.
Insulation Testers
Evaluates high-voltage harness insulation resistance to ensure safety and precision on hybrid/EV systems.
