Our Vehicle Diagnostic Philosophy


Modern vehicles are defined as "computers on wheels" and probably typical passenger car can be equipped between 40 and 100 tiny computers controlling Engine, Brakes, Transmission, Airbags, Windows and Doors, Steering System, Climate Control, Instrument Cluster, Towbar etc. etc. few names. In time some of them may develop faults which would effect safety, fuel consumption and drivebility. If you have a problem what would you do?

Once upon a time when engines were pure mechanics which fuel and air meets in the combustion chamber and ignited at the right time with no emission regulations and cheap fuel. You would need strong muscles to turn the steering wheel and heavy foot to apply brake. When the fault happens than you would take it to "mechanic" friend or get a bit dirty and fix it yourself. at that time mechanics were dirty, low earners and usually they become "mechanic" due to lack of education. 

But now harsh emission regulations, safety requirements and comfort demands engines and vehicle systems become "sensors" and "actuators" controlled by computers. Each computer communicates with each other with very fast rates more than ever. Unfortunately our "poor mechanic" is now out of business or struggling with only limited amount of exhaust, tyre and suspension work which he can coop. So if you have a problem where to go? Fixing modern systems require "high skills", "extensive equipments" and "knowledge". Those makes today's mechanics highly skilled and educated engineers. 

I personally know quite few mechanical and electronic engineers working in Automotive industry, including myself. I have quite often asked the question, why an Computer Engineer with a BSc and MSc degree would work in repair garage. Answer is simple; without my extensive electronic knowledge at component level and without understanding how electronic units are working on the vehicle, it would be impossible to resolve problems which I am dealing day to day basis.

Knowledge and Accessing Information

At Autotech Car Service we are fully subscribers of ErWin Information system for All Volkswagen, Audi, Seat, Skoda Vehicles. This is the exactly same system used by VW main dealers wordwide. Obtaining undisputed right information, wiring diagrams, tightening torques etc. is our key for efficient diagnosis and repair. Without this knowledge it would take guesswork to get results which would involve replacing unnecessary parts and big diagnosis costs.

For non VW group vehicles and component test values for VW vehicles we also use Bosch ESI[tronic] system. Bearing in mind that many electronic components on variety of vehicles are manufactured by Bosch. Having individual component target values in hand, we can verify whether output limits and patterns are within tolerances using oscilloscope, this would make us more advanced than main dealers. In fact this is the secret key of finding intermittent faults even main dealers are unable to identify.
