Reconditioned Audi A3 1.8 TFSI Gearbox – S tronic 7 – Ref. PNC

Reconditioned Audi A3 1.8 TFSI Gearbox – Reference PNC

This reconditioned gearbox is specifically designed for Audi A3 models fitted with the 1.8 TFSI engine (1798 cm³), engine codes BYT, CDAA and CJSA, reference PNC. It is a 7-speed S tronic dual-clutch gearbox, whose internal operation relies on precision mechanics that wear over time with repeated use. The reconditioning process involves a full strip-down of the gearbox, followed by thorough cleaning and inspection of every internal component. Wear parts such as gears, synchros, bearings and seals are systematically replaced. The gearbox is then reassembled to manufacturer tolerances and bench-tested to verify correct operation before dispatch.

Signs that your S tronic 7 gearbox needs replacing

On an Audi A3 1.8 TFSI, several warning signs should not be ignored: juddering or jerking during gear changes, abnormally slow throttle response, vibrations felt through the clutch pedal, the gearbox warning light illuminated on the dashboard, or the gearbox stuck in limp mode. These symptoms typically indicate advanced internal wear of the dual-clutch mechanism or the gearbox's mechanical components.

Exchange basis: the fast, reliable solution

This reconditioned gearbox is sold on an exchange basis: the reconditioned unit is dispatched first, before the old unit is collected, so the garage is never left without a gearbox. The old gearbox, with its casing intact, is only collected after the reconditioned unit has been delivered and fitted, and its return is required in accordance with our Terms and Conditions. This gearbox is sold without the mechatronic unit: it is neither supplied nor included in the sale, it is neither reconditioned nor tested, and remains the vehicle's original unit, to be reused by the customer. The dual-clutch assembly, however, is included with this reference PNC.

Compatibility

This PNC gearbox is compatible with Audi A3 models fitted with engine codes BYT, CDAA and CJSA.

Warranty and payment

This gearbox is sold with a 12-month parts warranty, subject to fitting by a qualified professional. Payment can be spread over multiple instalments, in up to 10 instalments.

EDEN BOITES supports you every step of the way, from your initial quote through to collection of the old unit.
