From 1997 to 2000, the company produced the 1.9-liter diesel VW AHF 1.9 TDI, which was fitted to popular German models like the Bora, Golf 4, and Audi A3 8L. A comparable ASV diesel engine with EURO 3 support replaced this engine in 2000.
1Z, AFN, AHF, AHU, ALH, AVG, AKU, and AEY are further models in the EA180 series.

Disadvantages of the VW AHF engine
Thrust failures are frequently caused by the turbine’s wedge geometry or the EGR valve’s damper;
Additionally, valve seats frequently burn out and compression decreases at high mileage;
This could result in a timing and overhaul due to a broken ribbed belt;
Start searching for leaks from the lower flange of the crankcase ventilation tube if your entire sump is filled with oil. A cracked cooling tee is typically the cause of this type of antifreeze leak.
