Servicing, Repairs & Cambelts

SEAT Cupra TSi Engine Servicing

At TC Garage, we provide the full range of SEAT and CUPRA dealer-level services without affecting your manufacturer’s warranty. From annual servicing, MOTs, and air conditioning regas, to repairs, wheel alignment, cambelt or timing chain replacement, ADAS calibration, and inlet port cleaning, we tailor every service to your vehicle’s exact requirements. All work is recorded to maintain your vehicle’s service history — in the service book for older models, or updated directly with SEAT or CUPRA digital records for newer vehicles.

We use genuine SEAT and CUPRA parts and carry out thorough inspections to spot potential issues before they become costly problems. Our meticulous approach helps improve reliability, maintain service history, and reduce the risk of long-term damage.

When it comes time for your MOT, you’ll benefit from our careful maintenance regime — well-serviced SEAT and CUPRA vehicles have a higher pass rate, helping you avoid common failures such as emissions issues, worn brakes, and suspension bushes.

Fault Finding & Diagnostics

The advantage of SEAT and CUPRA being part of the Volkswagen Audi Group is that they share the same diagnostic systems. At TC Garage, we use official ODIS (Offboard Diagnostic Information System) equipment, along with VAG-COM and other specialist tools, backed by years of hands-on experience to pinpoint faults quickly and accurately.

We focus on accurate diagnosis rather than the trial-and-error approach used by some garages. This expertise has earned us a strong reputation for solving problems efficiently. Many customers travel from across Surrey, East Sussex, South London, and the South Coast to have their SEAT or CUPRA diagnosed and repaired by our specialists.
