RPI is a mobile-first independent specialist, focused on diagnostic investigation and technical evaluation. We review the concern and location before discussing a suitable appointment.
01 / Advanced diagnostics
Find the cause, not just the code.
Warning lights, intermittent drivability faults, starting concerns and recurring issues demand more than clearing codes. The goal is systematic testing and evidence-backed recommendations.
- Fault tracing and verification
- Scan-data interpretation and directed testing
- Non-start and intermittent condition assessment

Answers, before appointments
A clearer way forward.
The right specialist experience begins with knowing what to expect. Here are a few practical answers before a visit is discussed.
Explore an assessment requestWhich vehicles can RPI assess?
We focus on Jaguar, Land Rover and Range Rover vehicles. Suitability depends on the model, the fault, available diagnostic access and where the vehicle is located. We review those details before agreeing to a visit.
Is this the same as booking a repair?
No. Our mobile focus is diagnostics, electrical and network fault tracing, and technical assessments. Repairs needing a lift, major disassembly or an equipped workshop are outside the mobile scope.
What if another shop has already worked on it?
Existing repair notes, fault codes and test results can be useful. A second opinion starts with the evidence already gathered, then identifies what still needs to be checked.
Do I need a fault code to request an assessment?
No. Intermittent concerns, unusual operation, warning messages and no-start symptoms can be described in your own words. The initial conversation establishes whether a mobile assessment makes sense.
Is Rover Performance Institute an authorized JLR dealer?
No. RPI is an independent specialist business. Factory certification refers to the individual technician’s qualifications, not manufacturer authorization or endorsement of the business.
