Workshop route
Planning a Cardiff visit to the Llandow workshop
Cardiff appointments take place at our single Llandow workshop in the Vale of Glamorgan, not at a city branch. The best route varies across Cardiff and with current conditions, so confirm the booking and check live directions before setting out. At Llandow, diagnostics, in-house calibration and dyno support can be planned around the actual vehicle.

A registration, vehicle specification, modifications and known faults help us discuss the appropriate booking before you travel.

Before you travel
Questions from Cardiff customers
Practical information about the workshop, booking and what happens before tuning.
Is there a Llandow Tuning branch in Cardiff?
No. This page describes coverage for Cardiff drivers. All appointments take place at the Llandow workshop in the Vale of Glamorgan.
What should I send before travelling from Cardiff?
Send the registration or full vehicle specification, relevant modifications, known faults and what you want to improve so we can discuss the appropriate booking first.
Can a warning light be checked before tuning?
Yes. Diagnostic investigation may be the right first step, and a calibration is not recommended simply because a vehicle has arrived for a tuning enquiry.
Does every Cardiff remap need a dyno session?
No single process suits every vehicle. On-site dyno testing and logging are available where they add useful measured information to the booking.
