Scania AUS4 Basic radio – front panel, no-power repair at OEMatic

The Scania AUS4 Basic radio is increasingly coming to us with a complete loss of power — the unit does not respond, it will not switch on. This is a common fault with this model, and at OEMatic we know how to remove it effectively.

How do you identify the AUS4 Basic model?

The easiest way: compare your unit with this photo:

Also check the sticker with the numbers on the casing — it should include:

  • Manufacturer name: Harman Becker
  • Model: AUS4 Basic or AUS4 Basic DAB
  • Scania logo: under the barcode
  • Vehicle it fits: Scania R, S, NGS

If you’re still not sure — send us a photo of your radio – we will confirm the model free of charge before repair.

Typical fault symptoms

The behaviour of the Scania AUS4 Basic radio with this fault is:

  • Will not switch on at all (may draw 0.6A)
  • No sound from the speakers, not even hiss
  • No illumination of the buttons or screen
  • The ammeter shows that it responds to manually pressing the power knob, yet there is no response on the screen.

Is your radio freezing on the start-up logo? That is a different fault — read how we repair it here.
