P0909 — Gate Select Control Error

Don’t put off the repair

Open this code in the appDownload the app

A fault code doesn’t yet mean the unit or sensor itself is faulty: often it’s the plug and connector leading to it.

Possible causes

What you can do yourself

  1. Drive only to a service centre
  2. Shift actuator check and adaptation — by a technician

Stop and don’t drive on if:

  • The Check Engine light is flashing
  • The temperature gauge is in the red or the overheating light is on
  • The red oil pressure light is on
  • Smoke from under the bonnet, a burning or petrol smell
  • Strong jerking, knocking from the engine, or the car barely moves

The explanation comes from the error code reference in the AvtoElektrik PRO app.
