Tuning Box for Wendland Vehicles

I bought a used tuning box for a 1.9 TDI 110hp Audi A4, manufactured in 1997.
The box has a hose connection; where should I connect it?
Thank you.
Alex.

Hello Sascha,

For the auxiliary box, this is the connection for the boost pressure. The box is activated (or deactivated) depending on the boost pressure.

I couldn't find a connection for the charging cable. (Everything is controlled using the under-pressure system.)

Hi.

The (VTG) supercharger is controlled with pressure to regulate the boosthttp://www.diesel-schrauber.de/forum/messages/135.html pressure.

Starting from the Authalbox, you need to tap into the boost pressure.

Depending on the version of the engine control unit, a thin hose runs from the intake manifold (behind the intercooler) to the engine control unit. This hose can be tapped into using a T-connector.
Alternatively, if the boost pressure sensor is located directly in the intake manifold, then the pressure tap needs to be created manually.
