2.0 TDI: No Power? Troubleshooting Guide

Hello,
I drive an A3 Sportback 2.0 TDI MJ '05 with the engine code BKD.
"Since yesterday, the car has had no power. It was parked outside overnight, and the problem started when I got back in. Absolutely no power. I've already replaced the mass airflow sensor (MAF), but it didn't help. Since there's no smoke, I'm also ruling out the turbo. Could it be damage from a rodent? Also, there's no sign of fluid leakage..."

Does anyone have any ideas about what might be causing this?

Warm regards,

We're probably not going to get very far without a VAG-COM diagnostic tool. It could be a lot of things. A faulty vacuum hose is definitely a possibility. You could check the vacuum lines for the VTG adjustment.
