Leon door lock

Hi, I noticed something while working on my Leon. The small LED in the driver's door isn't blinking anymore when I lock the car remotely. Also, the anti-theft alarm system seems to be out of order. Unfortunately, I couldn't get any further with VCDS. Could the driver's lock be the problem?

Please check all locks/microswitches for plausibility using the Multi-Wire Balancing (MWB) method.

Sure, no problem, I'll do it again.

The interior monitoring and alarm system is working again; it can be deactivated or activated via the driver's door lock cylinder. I read about this in the channel adaptation section and in the owner's manual . However, the indicator light in the door panel remains off .

Check if it works using actuator diagnostics.

No, that's not possible.

It's either the LED, the cable, or the door control unit that's defective. Just build them and apply some voltage.

Measure beforehand to see if and what arrives. Honestly, I'm not sure right now whether 12V is coming out of the control unit or just 1.8V.

The VCDS software includes a diagnostic function for the indicator light, which can be helpful in identifying the problem. This means the fault is likely located either on the wiring between the control unit (TSG) and the light, or within the light itself. The SSP 193 document can also be useful. However, I can't determine the voltage at which the light is operating from this information. Tomorrow, we'll start by working on the clutch, and then we'll remove the door panel.

17€ for such a small diode with a piece of plastic, that's quite expensive.

Was were you referring to?

I don't know. Expansion.
It should arrive sometime this weekend or so.
