Vehicle Diagnostics
A warning light on the dash means your car has logged a fault, and the sooner you know what it is, the less it's likely to cost. Our car diagnostics service at JTK Remapping in Dungarvan, Co. Waterford, reads that fault with dealer-level software, tracks it to its cause and gets you back on the road. We diagnose all makes and models.
Before the NCT, a service or a remap
A warning light is worth sorting before a pre-NCT inspection or your test. If you're booked in for general maintenance or car remapping, we can read the codes on the same visit, so the car starts from a clean bill of health.

How car diagnostics works
Every modern car has a network of computers watching its major systems, led by the engine control unit (ECU). When something goes wrong, they store a fault code. We plug in, read those codes and work back to the root cause, so you pay to fix the problem rather than one part after another. We specialise in warning light diagnostics and fault correction, airbag and ABS faults included.

Diagnostics questions
Enquire NowCar feels down on power?
Not every problem shows a light. If your car feels flat, a run on our dyno shows what it's making against what it should, and the fault codes usually point to why.
