  • Purpose: Checks for engine health by measuring the compression in each cylinder, which can help diagnose issues such as worn piston rings, valve problems, or head gasket failure.
  • Tools Used: Compression gauge or tester.
  • Purpose: Used to diagnose and clean carbon deposits from intake valves, which can affect performance, especially in BMW models with direct fuel injection systems.
  • Tools Used: Specialized walnut blasting equipment or cleaning tools.
  • Purpose: Evaluates the suspension and steering systems, including checks on shocks, struts, bushings, and ball joints, to identify wear and damage.
  • Tools Used: Diagnostic lift, suspension testers, and steering alignment machines.
  • Purpose: Assesses the health of the battery and the functionality of the alternator, ensuring proper charging and preventing electrical failures.
  • Tools Used: Battery tester, alternator tester, or multimeter.
  • Purpose: Checks for issues within the ABS system, including sensors, pump, and ECU, often by reading ABS-specific error codes.
  • Tools Used: ABS-specific diagnostic tools, such as the BMW diagnostic scanner.
  • Purpose: Identifies issues with the transmission, such as slipping, rough shifting, or fluid leaks, by scanning for fault codes and testing fluid levels and quality.
  • Tools Used: Transmission diagnostic tool, BMW-specific scanners
  • Purpose: Checks the fuel injectors, fuel pump, and fuel pressure regulators to ensure the fuel system is working correctly.
  • Tools Used: Fuel pressure gauges, injector testing equipment, and diagnostic software.

  • Tools Used: TPMS reset tool or specialized diagnostic equipment.
  • Purpose: Diagnoses issues related to the exhaust system, including the catalytic converter, oxygen sensors, and overall emissions system health.
  • Tools Used: Exhaust gas analyzer, O2 sensor tester, and smoke machines.
  • Purpose: Examines the car's electrical system, including lighting, wiring, fuses, and modules, to identify faults like short circuits or power failure.
  • Tools Used: Multimeter, circuit testers, and wiring diagrams.
  • Purpose: Inspects the climate control system, including refrigerant levels, compressor operation, and electrical components.
  • Tools Used: AC diagnostic machine, pressure gauges, and leak detectors.
  • Purpose: Reprogramming or coding of new or replaced modules (ECUs, sensors, etc.) to ensure they communicate properly with the vehicle's systems.
  • Tools Used: BMW coding tools like E-SYS, ISTA, or NCS Expert.
  • Purpose: Performs wheel alignment and tire balancing to ensure optimal vehicle handling and tire wear.
  • Tools Used: Alignment machine, tire balancer.
