Mat Armstrong’s Bugatti Veyron Refuses to Start, and Bugatti Won’t Even Answer the Phone

• Mat Armstrong’s Bugatti Veyron starts for two seconds then dies, leaving the team stranded and searching for answers
• After hours of diagnosis, the fault is traced to a recalled fuel pump control module that Bugatti knew about
• When Mat tries to call Bugatti for help, not a single dealership picks up the phone, but the repair bill is staggering

A million-pound car, a $4500 part, and nobody to call

The Bugatti Veyron is supposed to be the car that justifies its price tag with engineering perfection. Mat Armstrong’s example is doing the opposite. Fresh off a failed top speed attempt on his main channel, the Veyron has developed a new and crippling fault. It starts, runs for roughly two seconds, then shuts itself off as though someone has pulled the plug.

The symptoms point in two directions at once. It behaves exactly like an immobilizer fault, where the car starts on residual fuel in the lines and then cuts out when it fails to verify the key. But the diagnostic scan tells a different story. It reads “no communication with fuel pump control module,” which means the part responsible for regulating fuel delivery to the W16 engine has gone silent.

Mat and his team spend hours working through the possibilities. They strip the rear clam off the car at the Top Gear test track. They check every fuse on both sides of the engine bay. They call the tracker company to rule out an installation issue. They bring in a locksmith and diagnostics specialist to test the key and immobilizer system. The key reads fine. The immobilizer has no faults. Everything keeps pointing back to that one module.

Then comes the moment that changes the direction of the whole diagnosis. Mat unplugs the fuel pump control module entirely, and the car starts. It runs with a flashing engine light, zero fuel reading on the gauge, and almost no throttle response, but it runs. Without the faulty module telling the engine how to regulate fuel, the pumps default to a constant flow and the Veyron stays alive.

That confirmation leads to something even more telling. A search of the part number pulls up a recall document showing that 72 Bugatti Veyrons and Grand Sports were affected by this exact failure. The revised module, software version V3.03, was supposed to fix the problem. Mat’s car already has the updated version, and it has still failed.

What follows is one of the most painful sequences in the video, and it has nothing to do with the car itself. Mat calls Bugatti London. No answer. He calls the service centre directly. No answer. He calls Bugatti Paris, who claim to be open Monday to Saturday but do not pick up on a Monday at midday. He tries sales. They call him back within minutes. Service never does.

To prove the point, he calls Pagani in Manchester. They answer on the first ring.

By Tuesday, Bugatti Manchester finally responds. The fuel pump control module is in stock at their facility in Molsheim, France. The cost is $4500 for the part alone. The car must be transported to their workshop for them to fit it.

For anyone who has ever wondered what owning a Bugatti Veyron actually looks like when something goes wrong, this video answers that question in full. It is not the engineering that lets the ownership experience down. It is everything that comes after.
