A4 B6 2.5 TDI Fuel Injector Pump Failure

Okay, here's the translation:

"Hey everyone, I'm having a problem with my Audi. It's not running properly anymore. I suspect the fuel injection pump is broken. What do you think?" It's an A4 2.5 TDI with a build motor.

But in the measurement data blocks, you can see if the pump is defective, right? And if there are many zeros, does that mean it's working properly???

Hello,

First, check the most obvious things: whether the fuel injection pump is receiving enough fuel and whether it's drawing in any air bubbles. Then, check the timing of the belt drive, specifically the drive for the electronic stability program (ESP).

Best regards, Rainer.
