2018 Tiguan (STD KEY) with THAR-VW6 sending constant voltage to ignition switch

0 votes
I have a 2018 Tiguan MK2 with a standard key and automatic trans.

I had installed the THAR-VW6 and had my EVO-ALL on firmware 64.10.

With the T-harness installed, even without the EVO-ALL connected, the car's switch is receiving a constant high voltage and the vehicle will start with the key in the on position and pressing the break without turning the key.

This is also an issue with the vehicle's auto stop-start feature.

Because there is a constant voltage being sent from the ignition switch, the car will send an EPC error and the engine will not auto stop-start due to error.

I've tried turning on Push-to-Start; no change. in fact, this option turned on makes it so the car doesn't even try to start with the LOCK-LOCK-LOCK command.

Hello,

What connector did you use from the t-harness? A or B?

Also if possible please provide a picture of where the t-harness has been connected to on the vehicle.

Best regards
