Hello!
I have no idea how it is with the Beetle

. I only know that you absolutely cannot get to the turbocharger properly because it's located behind the splash guard in the Beetle. You can't even reach it with your hand if you just want to touch it, let alone take anything apart

.
What surprises me is... normally, the TDI runs fine if the injection timing is close to the limit. Does this only become noticeable during startup? I always thought that the TDI wouldn't run properly at all if the injection timing wasn't set correctly

.
Greetings.
