Hi, I have a 2.0 TDI (BKD), which has a timing belt, ran about 30k miles. (The car ran over 200k miles) I were at a mechanic, who said, that the car seems ok, but he thinks that the timing belt is misplaced. I do have a little high mpg, so I first checked the torsion value with VCDS. It's -1.0, but with the original belt it was -2.0, as I remember well. This shouldn't be a problem as far as I know. Then I removed the upper cover of the timing belt and I've seen that the left toothed belt sprocket's fixing screws have a ~7mm gap on the right (so retard), and the right toothed belt sprocket's fixing screws have a ~2mm gap on the right (so also retard). I marked the left toothed belt sprocket, so I can set back the original position later. Then I set the same position as on the right toothed belt sprocket, and turned over the crankshaft four times, just to be sure... Then I tried to start the car, and it did not started... After this I slowly moved back to the original position, and when the car first started, it started hard with higher idle rev (1100), high idle consumption (2,1l/h) and high idle stabilization values (1,2+) in VCDS (group 13). Then as I moved toward the original position, idle consumption and stabilization values decreased, until I reached the original position, where it started normally and with the usual values (0,7-0,8l/h idle consumption and below 0,7 idle stabilization values). Based on this test, I think, that the left toothed belt sprocket is misplaced with one or two teeth in clockwise direction (so should be turned back one or two teeth), and the talented mechanic made a compensation with the torsion value on the left toothed belt sprocket. Is it possible? How can I check, that I'm right or not? Thanks in advance!
