From the Workshop
The biggest difference between repairing a commercial vehicle and a passenger car is how the vehicle is used.
Most work vehicles spend every day carrying tools, stock or equipment, often covering high kilometres and operating in stop-start traffic.
Those operating conditions create different wear patterns and different repair priorities.
Understanding those differences is one of the reasons businesses choose Progressive Vans.
Commercial Vehicles Are Different
Work vehicles operate under conditions that passenger cars never experience. Higher loads, longer hours, multiple drivers, and less downtime between jobs all accelerate wear and create failure patterns that require specialist knowledge to diagnose correctly.

Common Commercial Repairs
The faults we see most often on commercial vehicles used for business.
Engine Warning Lights
High-kilometre commercial vehicles generate fault codes more frequently. Accurate diagnosis matters — replacing parts without identifying the root cause wastes time and money.
DPF Problems
Stop-start urban driving is the leading cause of DPF blockages in commercial vehicles. See our dedicated DPF cleaning page.
Brake Wear
Loaded commercial vehicles wear brakes faster than passenger cars. Regular inspection prevents costly rotor damage and keeps vehicles safe under load.
Suspension Wear
Carrying heavy loads accelerates suspension wear. Worn bushes, ball joints and shock absorbers affect handling, tyre wear and driver safety.
Turbocharger Faults
Turbo faults are common in high-mileage diesel commercial vehicles. Correct diagnosis is critical — many turbo failures are caused by oil supply or boost system issues rather than the turbo itself.
Cooling Problems
Overheating is a serious risk in heavily loaded commercial vehicles. Water pump failures, radiator leaks and thermostat faults need prompt attention.
Electrical Faults
Modern commercial vehicles rely heavily on electronic systems. Intermittent faults, sensor failures and wiring issues require proper diagnostic equipment to resolve correctly.
Oil Leaks
High-mileage commercial engines develop leaks from gaskets and seals. Left unaddressed, oil leaks lead to engine damage and costly repairs.

Recent Workshop Repair
A courier company booked in a Mercedes Sprinter after another workshop had replaced a boost pressure sensor without fixing the intermittent limp mode.
After carrying out a full diagnostic assessment we identified a split intercooler hose causing incorrect boost readings under load.
Replacing the hose solved the issue immediately and avoided unnecessary turbocharger replacement.
