In addition to engine conversions, big turbo kits, Custom-Calibrated ECU tuning and general servicing, JBS has always had a great reputation for quickly resolving complex faults with all VAG vehicles


There is no aspect of your cars mechanics or electrical systems that we cannot diagnose and repair. We have been around for long enough to have experienced most faults at least once and if we haven't, we'll have a good idea where to start!

Fault Finding has been made easier by the installation of a state-of-the-art dyno (rolling road). Using computer diagnostics and the computer-controlled dyno, running problems can easily be pinpointed and repaired.

Our diagnostic charges start from £32.50 + VAT for half an hour. 

Call us on 01246 455005 to book your car in for investigation.

Engine and Drive-Train upgrades are of course what JBS is famous for.

All products used have been proven to give maximum benefit and reliability and have been through vigorous testing, quite simply we don't use any parts that either haven't or aren't being used in our own vehicles.

While specializing in more modern vehicles, JBS have not forgotten that many owners still cherish their older cars and so can work their magic on whatever VAG car you own, be it an 8v, 16v, VR6 or TDI.
