RE: Volkswagen Touran 1T - no start
have you checked the ignition switch yet? Read in measured values from the steering column control unit when the ignition is switched on and when starting.

Check the ECU's kl30 wire under the battery tray. Sometimes it tears apart. If you have a VIN I can tell the colour of the wire.

without a diagnostic protocol and the VIN for vehicle data SLP etc. I cannot help you. I guess terminal 15 error, control or relay.
