View Full Version : Question 2018 S3 - Anti hijack

09-04-2018, 11:42 AM
I have fitted an aftermarket immobilizer to my S3 which works great. unfortunately I'm not able to get the anti hijack feature to work.

I can't discuss brands of makes on here because I'm pretty sure the UK re seller has some sort of deal with the manufacturer. I purchased it for a much more reasonable price from the manufacturer.

The fundamentals are pretty simple, while active it blocks startup and has an anti hijack feature (activated if the drivers door is opened with the gearbox in drive) which needs to be able to stall the engine.

The system has an analog output which sends out a 12v feed when anti hijack is activated and I need help with finding the best place to use this to stall the engine.

Any advice would be appreciated or is this even possible or a good idea.

Does anyone have any knowledge on how to electronically stall the engine on a 2018 S3 and can guide me in the correct direction on this?
