Audi A6 C4 ESP Diagram: 2.5 TDI, 140PS, AEL Engine

Hi everyone,

Please, experts, could you provide a diagram/image or links showing the exact screws I need to loosen to be able to rotate the fuel injection pump?

I've already adjusted the basic fuel injection timing for the diesel injection pump, and the VCD reading is 110-120 (too early), so I need to adjust the ESP a bit more to fine-tune the fuel injection timing dynamically.

I would appreciate any help you can offer.

Thank you in advance.

Roberts.

Hi.

You can actually see it best on the VP37, with three pieces in the area of the pulley, and a support screw at the back near the fuel injection lines.

Hello Ruedi,

Thank you for your message!

Also, genau was ich vermutete, war aber nicht ganz sicher. I'll check that.

Have a nice day!

Roberts.
