NW-KW-Versatz bei PD durch VAG-COM prüfen? | Posts 16+

If the fuel consumption is "OK" with regular diesel, then there is no misconfiguration.
It could also be due to the biodiesel, as there's a lot of questionable stuff being added to it right now due to the high prices.
I work for a company that develops biogas plants. This includes regularly taking and analyzing fuel samples. About 6 weeks ago, trace amounts of heating oil were even detected in one of the samples.
Try filling up the tank in a different city, if possible, and then test it again.

This "rubber damper" or, more accurately, the hub, comes in different versions depending on the motor. These versions include: a small hub only (where the ZR wheel is attached), a small hub with a sensor ring, or a version where a type of "vibration damper" is mounted around the small hub.
In all cases, however, the part that connects the inner wheel to the outer wheel is not made of rubber, but of metal, with a material similar to that of the inner wheel. Therefore, there should be no stretching or deformation in that area.
Quite the opposite - if it's successfully attached and the new one is improperly screwed on, it will break in the middle.

However, it's possible that in the latest version, the sensor ring is connected to the hub via the rubber of the "vibration damper." If this rubber were to soften and twist towards the axle, it could potentially cause the value detected by the sensor to deviate, while the actual position of the camshaft remains correct.
