I would recommend you a friend 2.4 D, but it's hard to find a well-kept copy and the engine itself is definitely not worse than 1.9 D or 1.9 TD and will burn the same and certainly has no worse acceleration despite the lack of a turbine. And one more thread or sometimes in the T4 the 2.4D engine did not have four cylinders anymore, because probably the older engine installed in the VW LT had five cylinders, no one will tell you exactly what it is like. A friend has been driving the VW T4 2.4D for five years and only parts are replaced, such as pads, tips, filters and oil. And yet such a curiosity for you, during this winter 27 degrees of his Audi A6 2.5 TDI 2001. it did not ignite and good old VW from the very first time, even in winter, is reliable. As for the 1.9 TD engines, I have one myself in my Passat B3 and I am not complaining, but the turbines are falling, I have already bought such a car, unfortunately, but it can be overcome because during normal driving, a lot of oil does not take up and you do not need to refill it so often. When it comes to overheating the 2.4D engine, this has never happened to a friend, so I recommend the 2.4D engine if you search well, maybe you will find a copy with a well-kept engine.
