Faults & System Testing

Problems happen...

Vehicle breakdowns are rare events these days and, generally speaking, modern cars are super-reliable. However, when a fault does occur, manufacturers are often heavily invested in making sure that you are not able to fix it yourself. Most people know they're going to need reliable diagnostics to find the problem and, ultimately, resolve it.

Trust Us to Help You

Reliable diagnostics...

Here at Diamond Motors we only work on Renault, Renaultsport, Dacia and Nissan vehicles. We use dealer-level diagnostic systems, technical services, process documentation and wiring schematics that are specific to your vehicle. This knowledge base and information allows us to make far more informed and accurate decisions, saving you money.

"We don't like guesswork and try to encourage our customers to prove the fault, before potentially wasting hundreds of pounds on work and parts that aren't required."

Vehicle Networks

CAN? K-Line? Help...

These multiplexed networks of machines, controllers and computers in our cars are supposed to make life easier for all involved - but that's not always the case. To make it even trickier, manufacturers like to keep customers on their toes by changing how things are done. Of course, no two manufacturers do things in exactly the same way either.

This makes buying equipment (that can reliably communicate with your vehicle) an expensive process that can cost thousands to buy and run each year. There is no such thing as a single piece of equipment that works well on all vehicles. Most aftermarket professional equipment will have strengths in some areas yet lack essential features elsewhere. As vehicles increase in complexity and cost it is imperative that you get the most reliable information and advice available to help identify the area of concern.

Live Data - Reading Between the Codes

Generic fault codes vs. live data and manufacturer specific codes

Fault codes can be a great asset, helping to identify an area specific to a problem. But here's the real question... are generic fault codes specific enough to tell you exactly where the fault lay?

The honest answer is simple - no, they are not.
If a component is declaring a fault then the issue could still be in one of three areas - the component itself, the wiring between the controller / component, or another related issue from elsewhere that is affecting the output of whatever the component is controlling or measuring.
