When you spend your week covering miles across the Midlands between client boardrooms and networking events, a reliable car isn’t a luxury. It is a mobile office. So when our Audi had clocked over 200,000 miles doing exactly that, we had no intention of parting with it.
Then came a fault that baffled the trade.
Without warning, the car began refusing diesel at the pump. Worse still, the plastic fuel tank beneath the car had expanded like a balloon under extreme internal pressure, physically pushing the rear seat base upwards into the cabin.
We replaced the tank. A few hundred miles later, the replacement tank ballooned. We took it to a specialist, replaced the high-pressure pump, fitted a third tank, and invested heavily in keeping the car on the road.
Last month, the back seat rose again. Three tanks destroyed in just 3,000 miles. After investing over £5,000 into the vehicle since the spring, its final valuation from the salvage yard came in this week at a sobering £320.
When you have built, scaled, and exited businesses, you learn to look at expensive failures objectively. Stepping away from the wreckage of that car, it struck us that the exact sequence of events that killed our Audi happens in mid-market boardrooms every single week.
1. Dashboard Blindness vs First Principles
Why did three fuel tanks fail in the exact same way? Because modern workshops rely almost entirely on what the diagnostic laptop tells them. You plug the car into the computer, and if there is no electronic sensor inside a blocked plastic breather pipe, the screen flashes green: No Fault Code Found.
Instead of stepping away from the screen and using first-principles engineering to test if air could physically escape the tank, the technicians trusted the clean dashboard and simply swapped the broken part, transferring the blockage straight onto the next tank.
In business, I see leadership teams fall into this trap constantly. They stare at management accounts, CRM dashboards, and lagging KPIs that look healthy on paper, whilst ignoring a fundamental operational blockage on the shop floor. If you only manage what your software measures, you will keep replacing people, systems, and suppliers without ever fixing the underlying restriction that caused them to fail in the first place.
2. Polishing the Comforts Whilst the Core is Compromised
Just a couple of months before the final failure, I authorised over £2,000 for a major service, a new air conditioning compressor, and parking sensors. At the time, the logic seemed completely sound. When you are driving in summer suits and parking in tight city centres, you need the air conditioning to work and the sensors to beep.
Yet while we were investing in usability and comfort, an intermittent engine timing fault and oil dilution issue were quietly brewing underneath.
How often do businesses do the exact same thing? A company has a fatal flaw in its gross margin, its client retention, or its senior leadership alignment. Instead of halting everything to fix the engine, the board signs off tens of thousands of pounds on a shiny website rebrand, an office refurbishment, or a new piece of software to make day-to-day life more comfortable. Making a business more pleasant to operate means nothing if the core mechanics are out of time.
3. The Discipline to Walk Away for £320
The hardest decision in business is rarely how to start something. It is knowing when to call time.
When you have just spent £5,000 on an asset, every instinct in your body tells you that you cannot possibly let it go for £320. You convince yourself that you are just one more invoice, one more diagnostic session, or one more part away from unlocking the value of everything you have already spent.
Whether it is an underperforming product line, a commercial property that won’t stack up, a bad strategic hire, or a high-mileage diesel estate, the market does not care how much money or emotion you have already invested. The £5,000 is gone. The only commercial question that matters today is whether the next pound you spend will generate a return.
When the answer is no, true commercial discipline is taking the £320 salvage cheque, drawing a hard line under the asset, and putting your energy into a vehicle that will actually get you where you are going next.
Where in your business are you still paying to fix a symptom because you have already invested too much to walk away?
