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.
