Our Workshop

Servicing & MOT

J&P Autos is more than a car dealer. Our fully equipped workshop handles everything from MOT testing and routine servicing to complex diagnostics and major repairs.

MOT Testing

We're a fully approved Class 4 MOT testing station for cars and light vans up to 3,000kg. Our experienced testers have been carrying out MOTs for decades. We'll give you an honest assessment — no upselling, no unnecessary work. If your vehicle needs attention, we'll explain everything clearly and give you a fair quote.

Vehicle Servicing

Regular servicing keeps your car running reliably, safely and efficiently, and helps it hold its value. We offer a range of service packages to suit your car and your budget, from a minor service with an oil and filter change and essential safety checks, right up to a comprehensive major service. We use quality parts and follow manufacturer schedules on all makes and models, and we'll always tell you honestly what your car needs, and what it doesn't.

Engine diagnostic testing at J&P Autos Cardiff

Diagnostics

Modern vehicles rely on complex electronics. Our diagnostic equipment reads fault codes from your engine management, ABS, airbag, and other systems. We can accurately pinpoint problems and fix them right — saving you time and money compared to trial-and-error repairs.

Car battery and electrical fault testing at J&P Autos Cardiff

Electrical Repairs

Today's cars rely on electrics for almost everything, and a small fault can cause big headaches. From flat batteries and failing alternators to starter motors, wiring faults, lighting, central locking and electric windows, our technicians track down the root cause and fix it properly. No guesswork, no replacing parts that aren't needed. Warning light on the dash? Bring it in and we'll find out why.
