vehicle diagnostics
​At Kreskas Automotive, we specialise in diagnosing modern vehicles with dealership-level accuracy. Today’s cars use advanced electronic systems and complex mechanical components, which means that finding the root cause of a fault requires more than just experience — it requires the right diagnostic equipment and technical knowledge.
We invest in factory-level scan tools, testing equipment, and continuous training so we can provide fast, accurate, and cost-effective diagnostics for European, performance, and everyday vehicles.
​
Engine Diagnostics
Modern engines feature direct injection systems, turbocharging, and electronic valve timing. When problems occur, symptoms can range from poor performance to warning lights on the dashboard.
Our workshop is equipped to perform:
​
ECU Scan & Live Data Analysis – Accessing manufacturer-specific fault codes and monitoring real-time engine data.
Actuator Testing – Directly controlling injectors, solenoids, and throttle bodies to verify performance.
Compression & Leak-Down Testing – Identifying mechanical issues such as worn piston rings, valves, or gaskets.
Oscilloscope Testing – Checking ignition patterns and sensor signals with pinpoint accuracy.
​
Transmission Diagnostics
Automatic, DSG/DCT, and CVT transmissions rely on both hydraulic systems and electronic control modules. A small fault can cause slipping, harsh shifts, or complete failure.
​
We carry out:
Transmission Scan Tool Testing – Reading data for solenoids, clutch packs, and valve bodies.
Adaptation Resets & Coding – Ensuring the TCM relearns after repairs or servicing.
Mechatronic Unit & Valve Body Testing – Identifying hydraulic or electronic faults.
Live Data Monitoring – Checking pressures, shift times, and gear engagement.
​
Cooling System Diagnostics
Cooling systems in modern vehicles are electronically controlled and vital for engine health. Overheating can cause severe damage if not diagnosed correctly.
​
Our testing includes:
Pressure Testing – Detecting leaks in radiators, hoses, and seals.
Electronic Thermostat & Pump Testing – Using scan tools to command components on/off.
Temperature Monitoring – Confirming correct ECU-controlled cooling performance.
Battery & Electrical System Testing
Today’s vehicles rely on stable electrical power for everything from engine control to infotainment. Weak batteries or wiring faults can cause unpredictable issues.
​
We provide:
Battery Load Testing – Measuring real-world capacity and cold-crank performance.
Charging System Testing – Checking alternator output and regulator function.
Wiring & Module Communication Testing – Tracing faults in CAN bus and control modules.
