VAG 2.0 TDI Engines and Haldex pump failures

The famous Volkswagen Group 2.0 TDI engine, coupled with the 4Motion (Haldex) transmission, equips millions of vehicles in Europe (Tiguan, Passat, Skoda Kodiaq, Seat Ateca).

The explosive cocktail of torque and weight

These heavy vehicles (SUVs) with high engine torque place an enormous strain on the Haldex multi-plate clutch during acceleration. Friction is intense, metallic sludge creation is accelerated. Without a filter (Gen 5) and with a recommended oil change only every 3 years or 40,000 miles, the precharge pump failure is inevitable.

Join VAG group victims to force a technical recall and a modification of the official maintenance plan.
