Reconditioned Volkswagen Tiguan 2.0 TDI Gearbox

Six engine codes over eleven years: how the Tiguan 2.0 TDI gearbox evolved from 2007 to 2018

The Tiguan 2.0 TDI didn't make do with a single engine or a single transmission across its first generation. Between 2007 and 2018, six engine codes came and went — CBAB, CFFB, CFGB, CUVC, DFG and DFGA — and the gearbox fitted varies depending on the year of first registration. The earlier years (CBAB, CFFB, CFGB) correspond to 6-speed manual gearboxes; the more recent codes, notably CUVC, DFG and DFGA, can be paired with a DSG 7. Mixing up the two families when placing an order is the most common pitfall in this area.

6-speed manual or DSG 7: two distinct identification approaches

The 6-speed manual and the DSG 7 share neither the same architecture nor the same failure symptoms. On the wet-clutch DSG 7 (DQ500, used on high-torque 2.0 TDI variants), juddering in town driving or hesitation on cold starts are well-known signs of dual-clutch wear. The gearbox is supplied with a new dual clutch, without mechatronic unit: this point determines the diagnosis required before ordering. For the manual, difficulty selecting 3rd or 5th gear and sump leaks are the usual warning signs on first-generation engine codes.

Check the engine code first and foremost

On the Tiguan 2.0 TDI, the same production year can correspond to different engine codes depending on the trim level or the target market. The engine code, stamped on the block and available in the vehicle's documents, is the only reliable criterion for selecting the correct reference. EDEN BOITES offers these gearboxes in two ways: on an exchange basis, or as a full rebuild to 0 km of your own unit.
