How you'll learn
The programme is 100% online on the SEIUM campus, with downloadable material, recorded classes and an assigned technical tutor. There are no fixed timetables: you progress at your own pace within the intake, so you can combine it with your job.
Each module combines theory, guided reading of the original standard and applied exercises. The working software is Bosch ESI[tronic], PicoScope, Innovate LogWorks and Microsoft Excel, in free, academic or evaluation versions. Testing is studied through real procedures: pressure measurements on K-Jetronic systems, injector flow tests and oscilloscope diagnosis of analogue sensors. Assessment is continuous by module, plus the final Master's Thesis.
Standards covered: EN 228, Directive 70/220/EEC, Real Decreto 892/2013, Directive 2014/45/EU, Directive 91/441/EEC, UN Regulation No. 83, SAE J1349, Directive 2009/30/EC.
