Audi a4 b6 - Strange knocks in the engine above 2000 rpm 1.9 TDI AVF

If under load it is a bushing or a piston pin, if, regardless of the load, it is rather a timing, right after firing until reaching the temperature or all the time?

Exactly as my colleague writes bolus11. I had this engine in the T5, it is a pity to talk about the armored 1.9 TDI is already a legend 130 km, in my opinion too much for this 90 horse unit I agree. I made almost 600,000 with the old 2.5D Transit and the compression died only in the summer, in the T5 only 480,000 and the timing flew. As the mechanic told me, the bushings lost pressure first, then there was no pressure on the top of the engine and its end. Currently, I am targeting the Opel Vivaro 3.0 TDCI from across the Oder with a mileage of 231,000, of course, I estimate that it has 431 Buddy, pospiech8, can check if you have an authentic mileage
