Reconditioned Volkswagen Caddy 1.9 TDI Gearbox

Caddy 1.9 TDI (2004–2010): 5 or 6 speeds — two gearboxes for two engine codes, which one is yours?

On the Caddy 1.9 TDI produced between 2004 and 2010, two configurations exist side by side: a 5-speed manual and a 6-speed manual, allocated according to the engine code. The engine code — BJB or BLS — stamped on the block is the essential starting point, as the year alone is not enough to distinguish between the two families.

BJB and BLS: different profiles, different gearboxes

The BJB (105 hp, available from 2004) is generally paired with the 5-speed gearbox, whilst the BLS (105 hp, introduced from 2006 with improved exhaust gas recirculation) may be fitted with the 6-speed depending on the vehicle's configuration. Mixing up the two families leads to bell housing or final drive ratio incompatibility: the references GQN, JCY, LFZ, LBS, KRY, JCS, GQR cover the full range, but each one corresponds to a specific engine code / number of speeds pairing.

Commercial use and gearbox stress

The Caddy 1.9 TDI is frequently used as a light commercial vehicle carrying regular loads, which accelerates synchromesh wear — particularly on 2nd and 3rd gear in the 5-speed. The most common symptoms before complete failure are difficulty selecting gears when cold and a crunching noise when downshifting under load. The 6-speed, less common on this engine, shows more reported issues related to the differential in mixed urban/A-road use at high mileage.
