The light is a symptom, not the answer
A dashboard warning on a Leicester delivery vehicle tells the driver that something has gone wrong. It rarely says what. The same lamp can come from a failed sensor, a chafed wire, a fuel problem or a fault in the exhaust after-treatment, and swapping parts until it goes out is an expensive way to find out which. We read what the vehicle's systems are reporting, test the circuit or component involved, and confirm the cause before anything is replaced.
Faults that depend on the route
Leicester vehicles often split their time between the city and the motorway, and some faults only appear on one of them. A unit that behaves itself around the ring roads might derate on a long, loaded run down the M69 towards Coventry. A van that does nothing but short hops between the garment district and the city's shops may never get hot enough to keep its emissions system happy. When you ring, tell us where the vehicle was and what it was doing when the problem started. That detail often points at the fault faster than any code.
Intermittent faults need patience. If a light comes on during a long run and has cleared by morning, we will want to know how often it happens, at what speed or load, and whether anything changed recently: a refuel, a repair, a different trailer. With that picture we can test under the right conditions instead of guessing.
Where the diagnosis happens
Our technicians carry diagnostic equipment in the vans, so a lot of fault finding happens at the roadside or in your Leicester yard. If a vehicle has gone into limp mode on the M1 near junction 21 or 22, ring 01332 916028; limp modes protect the engine, and nursing it onwards can turn a sensor fault into a mechanical one. When a fault needs the vehicle on lifts, longer testing or parts we don't carry, it comes to our workshop at Melbourne, which takes booked work Monday to Friday between 07:30 and 17:00.
Electrical problems in a city fleet
Vans and rigids that open their doors dozens of times a day around Leicester Market, Highcross and the city's shops take a toll on wiring, lighting and charging. Corroded connectors and tired batteries are behind a good share of the electrical faults we trace. Finding the actual break in a circuit, rather than fitting another lamp or another battery, is what stops the same job coming back next month.
What you get afterwards
You get a plain account of what failed, why it failed and what we did, plus anything else we noticed that should be looked at before the next inspection. If a repair is only temporary to get the vehicle home, the technician will say so before leaving.
