Volkswagen Amarok – Oil leak in engine/transmission area
A customer mentioned that their 2013 VW Amarok 1.6L diesel had an oil leak. The leak is more noticeable on the engine oil sump area adjacent to transmission. We suspect a faulty transmission input shaft oil seal, but the customer doesn’t want us to remove the transmission to investigate. Could anything else be causing the leak?
This issue affects several VW models with 1.6/2.0L diesel engines. The oil leak is due to oil travelling along the retaining bolts for the flywheel or flexible drive plate. Remove the transmission assembly and the flywheel or flexible drive plate. Clean the threads in the crankshaft flange. For vehicles with a flexible drive plate, apply a small amount of sealing compound to the thread of the retaining bolts as indicated (Fig 2.1). For vehicles with a flywheel, apply a small amount of the sealing compound to the thread of the retaining bolts as indicated (Fig 2.2). Do not use an impact wrench to tighten retaining bolts. Ensure retaining bolts are tightened to the correct torque, and refit the transmission assembly.
