Diploma in Off-Road Semi-Active Suspension Systems
Online postgraduate diploma of 800 hours in off-road semi-active suspension systems, structured in 8 modules covering off-road vehicle dynamics, variable damping dampers, sensors and data acquisition, control strategies, simulation and validation, integration in off-road competition and functional safety, with an assigned technical tutor.
Diploma in Off-Road Semi-Active Suspension Systems — studying from Ireland
Ireland has an active heritage vehicle and classic machinery community, supported by clubs, restoration workshops and specialist suppliers serving classic cars, motorcycles and agricultural equipment. Engineering skills in this area combine historical knowledge with modern techniques in fabrication, materials and diagnostics. Restoration work is often linked to heritage conservation and museum collections, and classic vehicles operate under national roadworthiness and vehicle registration rules. Professional bodies and enthusiast organisations help maintain standards and knowledge across the sector.
Fees for Ireland: €1,290 (Euro), with instalments and employer sponsorship available.

Questions from Ireland
Is there a recognised professional body in Ireland for classic vehicle restoration?
Classic vehicle restoration in Ireland is largely a craft and hobby sector, supported by enthusiast clubs and heritage bodies rather than a regulated professional title. SEIUM's qualifications are private and not accredited by any national body, so they do not confer membership or formal recognition. Check the requirements of any club or body you wish to join.
Would Irish restoration businesses or employers value this qualification?
Restoration businesses in Ireland often rely on hands-on skill, reputation and portfolio work. A private online qualification may add to your CV, but employers decide for themselves whether it is relevant. Your final project can help show your capability, though there is no guarantee of any outcome.
Can I study this part-time while keeping my current commitments?
Yes, the programme is 100% online and taught in English, so you can study from home around existing commitments. Durations are 300, 800 or 1,900 hours depending on the course, so plan your schedule accordingly. Fees can be paid in instalments, and each student has an assigned technical tutor.
Take the controls.
Run a real engineering trade-off from this field. Move the sliders, watch the model react in real time and beat the challenge.

How you'll learn
A 100% online programme 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 each intake, so it fits around your job.
Each module combines theory, guided reading of the original standard and applied exercises. The working software is MATLAB/Simulink, Adams Car, CarSim, MoTeC i2 and IPG CarMaker, in free, academic or evaluation versions. Testing is studied through real procedures: damper characterisation on a test rig, dune and rocky-track tests with telemetry, and hardware-in-the-loop testing of the control unit. Assessment is continuous by module, plus the final project.
Standards covered: ISO 2631-1, ISO 8608, ISO 26262, FIA Cross-Country Rally technical regulations (Appendix J, Articles 285 and 286), ISO 11898, ISO 8855.
Build it end to end
Your final project follows the real engineering workflow, step by step, reviewed by your tutor.
