The 1.9-liter VW AFN 1.9 TDI diesel engine was produced by the company from 1996 to 2000 and installed on the most popular models, and is most known for the Passat B5. In fact, such a diesel engine differs from the AHU unit by the presence of a turbine with variable geometry.
The EA180 series also includes: 1Z, AFN, AHF, AHU, ALH, AVG, AKU, AEY.

Disadvantages of the VW AFN engine
- This engine is very reliable and the problems described below happen on a big run;
- Quite often there is a gesture of the saddles of the valves and, as a result, the loss of compression;
- The fault of the failures in traction is usually the jammed geometry of the turbine and the EGR valve;
- Often, the lower flange of the crankcase ventilation tube bursts and the lubricant begins to oozes through the pallet;
- The breakthrough of the auxiliary belt is very dangerous here, as it can get into the timing.
