The 1.9 TDI is arguably one of the best diesel engines ever made by the VW Group if we’re talking reliability. It powered millions and millions of cars sold by VW, Audi, Skoda, and SEAT, including the B6 generation of the A4. This particular example is a high-mileage 2003 Audi A4 Avant with nearly 370,000 kilometers (229,907 miles) on the clock still going strong while doing a top speed run on the Autobahn.
The author of this video, No Limit Autobahn / YouTube, says the 17-year-old wagon is still running on the original engine, clutch, and five-speed gearbox. The A4 Avant B6 (eventually) got up to 137 mph (220 km/h) and looked impressively stable and refined while doing its thing. Needless to say, the top speed run was conducted on one of the remaining unrestricted sections of Germany’s famous highway. In other words, no speed limits were broken.
Judging by the condition of the interior, the 2003 Audi A4 Avant has been in good hands as the car isn’t really showing its age. We could say the same thing about the exterior, flaunting glorious OEM hub caps we frankly haven’t seen on an Audi in quite a while.
It would be interesting to find out how much power the 1.9 TDI fitted to this 2003 Audi A4 Avant still delivers by putting the oil-burner on a dyno. Back in the day, the engine was good for 101 horsepower and 250 Newton-meters (184 pound-feet) of torque – respectable numbers for the early 2000s.
It’s impressive when you think about how far diesel engines have come in the last couple of decades considering the base A4 diesel with its 2.0 TDI produces 136 hp and 320 Nm (236 lb-ft). You also get the power much sooner, with the full horsepower kicking in at 3,000 rpm whereas the 1.9 TDI had it at 4,000 rpm. Torque arrives from as low as 1,500 rpm in the latest A4 diesel as opposed to 1,900 rpm in the B6-gen model.
Despite the costly Dieselgate, the TDI still has a future at the VW Group during this transitional period from combustion engines to the EV era.
