Today I had the privilege of being interviewed by the Devi Show camera crew regarding consumer-related motor industry matters. After 36 years in the automotive industry, thousands of assessments, courtrooms, workshops, and engine failures, I discovered something rather fascinating — there is apparently a massive difference between vast experience, real life experiences… and standing in front of professional cameras trying not to look terrified. Thank you Ruben for the guidance.

Fortunately, my wife later reassured me by saying I looked like “George Clooney ate Brad Pitt,” which I have chosen to accept as a compliment of the highest order.

On a more serious note, my fight for the consumer has intensified significantly over the past few years. I have been blessed to assist members of the public in numerous vehicle disputes, technical investigations, and dealer return matters, many of which have been successfully resolved through evidence-based forensic reporting.

I firmly believe the consumer remains the driving force of the economy and deserves fairness, transparency, and respect at all levels of the motor industry. It is both humbling and rewarding to be trusted by the public in matters that often carry major financial and emotional consequences.

Over the past few months, my silence on social media has not been due to inactivity, but rather due to intense focus behind the scenes.

I have been deeply involved in the development of three advanced EV training modules, two advanced engine failure programmes, and the ongoing refinement of assessor and estimator training material. The deeper I move into the worlds of electric vehicle architecture, thermodynamics, diagnostics, tribology, and modern engine failure analysis, the more I realise how rapidly our industry is evolving.

Life behind the PC has changed my thought process considerably. Long hours of research, technical analysis, module development, and continuous learning have expanded my appreciation for the complexity of modern vehicles and the responsibility carried by those who assess, diagnose, and repair them correctly.

What started as training development has become a personal journey of growth, humility, and renewed passion for this industry. The technology is advancing at a remarkable pace, and I believe those willing to keep learning will help shape the future of automotive assessment and repair.

Sometimes growth happens quietly — away from the noise, behind a screen, buried in diagrams, failures, calculations, and late-night notes. But that quiet work often builds the strongest foundations.

Looking forward to sharing more soon.

Downstream Failures vs. Workmanship: Understanding Modern Engine Complexity

In recent years, a recurring pattern has emerged during post-repair assessments: once a repair has been completed and the vehicle returned to service, subsequent faults are often attributed directly to the repairing workshop. While workmanship must always withstand scrutiny, it is technically inaccurate to assume that every post-repair failure originates from the repair itself.

Modern engines operate within exceptionally tight tolerances, governed by a dense network of sensors, control modules, and emissions systems. When a primary failure occurs—such as a turbocharger malfunction—it seldom exists in isolation. The failure event often initiates a cascade of secondary effects within the system.

A practical example illustrates this clearly. Following a turbocharger replacement, a vehicle may initially present as fully restored. However, over time, issues may arise with the Diesel Particulate Filter (DPF) or catalytic converter. This is not necessarily indicative of incorrect installation or defective workmanship. Rather, it reflects the delayed consequences of the original failure. Oil contamination, incomplete combustion, or excessive exhaust particulates introduced prior to the repair may only manifest once the engine is operating again at optimal efficiency. The newly installed turbocharger, functioning correctly, can effectively “unmask” the next weakest component in the system.

This phenomenon extends beyond mechanical components. Sensors and actuators—integral to modern engine management—may also degrade or fail independently. A marginal sensor, previously operating within tolerance, may fall outside acceptable parameters once system pressures, temperatures, or flow rates are restored to specification. Diagnostic fault codes generated in such cases can misleadingly implicate recent repair work, when in fact they reflect pre-existing or unrelated deterioration.

The underlying issue is a misalignment between expectation and technical reality. Repairs address identified faults based on available evidence at the time of inspection. They do not, and cannot, pre-emptively renew every component that may have been compromised indirectly.

The industry is transitioning into a space where traditional repair logic is no longer sufficient. Accurate fault diagnosis now requires a forensic understanding of failure chains, system interactions, and delayed symptom development. Without this depth of insight, there is a risk of misattributing responsibility and undermining technically sound repairs.

In conclusion, not all downstream failures are a consequence of poor workmanship. Many are the natural progression of complex systems recovering from an initial failure. Recognising this distinction is essential—for repairers, insurers, and consumers alike—if we are to maintain fairness, technical integrity, and trust within the repair process.

Repair Feasibility Approach – Electric Vehicles

Repair feasibility on electric vehicles is fundamentally driven by the disproportionate cost and sensitivity of high-voltage and electronic systems when compared to conventional internal combustion vehicles. The economic threshold is therefore reached far earlier, requiring a disciplined, reverse-engineered quotation methodology that prioritises high-value components first.

The assessment should commence with the high-voltage battery pack, as this represents the single most expensive and safety-critical component. Even in the absence of visible damage, the battery must be evaluated for structural integrity, internal cell stability, and potential isolation faults. If the battery is confirmed serviceable, attention should then shift to the inverter and electric drive unit (motor), both of which are precision-controlled components highly susceptible to impact-induced internal damage.

Thereafter, the evaluation progresses through the vehicle’s electronic control architecture, including all relevant control modules responsible for power management, safety systems, and communication networks. These systems are interdependent, and failure in one unit may cascade across the entire network. Following this, all high-voltage cabling (orange-coded systems) must be inspected for insulation compromise, continuity integrity, and connector damage, with replacement typically mandated where any defect is identified.

Only once the electrical and high-voltage systems are cleared should the assessment transition to the structural platform, including chassis alignment, underbody integrity, and mounting points for critical components such as the battery housing. Thereafter, conventional repair items—namely body panels, trim components, lighting systems, doors, and exterior mouldings—can be evaluated.

In contrast to internal combustion vehicles, where repair costing often begins with visible structural or cosmetic damage, electric vehicle assessment requires a “quote-back” methodology, prioritising high-cost electronic and energy systems first. This approach reflects the reality that even minor compromise within these systems can render the vehicle economically unviable to repair.

Accordingly, the repair strategy for electric vehicles must be both technically sequenced and economically informed, recognising that electronic component pricing and system complexity significantly elevate the probability of total loss when compared to conventional vehicles.

Credential integrity is becoming an increasingly relevant risk factor in technical investigations, yet it is often overlooked until something goes wrong, like a defective workmanship claim.

In the course of my engine failure assessments and forensic evaluations, I have encountered a growing number of cases where the underlying issue was not purely mechanical, but procedural—specifically, the presence of falsified or misrepresented credentials. These have included questionable technician qualifications, unverifiable training claims, and in some instances, irregular or invalid driver licensing linked to vehicle handling and testing.

Modern engines operate within extremely tight tolerances. The margin for error is minimal. When individuals without the appropriate skillset, training, or verified competency are involved in diagnostics, repairs, or testing, the risk of catastrophic failure increases significantly. What may initially present as a mechanical defect often traces back to a competency gap masked by inaccurate documentation.

From an employer and operational standpoint, this introduces several layers of exposure:

Technical risk (incorrect repairs or diagnostics)
Financial risk (repeat failures, warranty disputes, insurer rejection)
Legal risk (liability arising from negligent workmanship)
Reputational risk (loss of client trust and credibility)

It is therefore no longer sufficient to rely on submitted documentation at face value. A more structured approach is required.

Practical measures should include:

Independent verification of qualifications with issuing institutions
Background and employment history checks
Validation of driver licences through official channels
Ongoing competency assessments, particularly for high-risk mechanical work
Clear procedural controls and supervision within the workshop environment

The objective is not to create unnecessary administrative burden, but to ensure that the individual entrusted with complex mechanical systems is demonstrably competent to do so.

In my experience, many of the most severe and costly failures could have been prevented at the recruitment or verification stage. As vehicle technology continues to advance, the industry must respond by tightening its standards—not only in tools and processes, but in the people who apply them.

Credential verification is no longer a formality. It is a fundamental control in preventing technical failure and protecting all parties involved.
