Hi, first I realize this post is 2 years old but, I’m trying to help your future lol. I hope you didn’t buy it? It’s going to cost more than you realize. It’s only good as a track car and it’s got the 2litre so it’s underpowered. Also, it looks like it’s no longer straight so, it will never drive proper on track or street. I have owned an early 85 944 an 88 turbo 944 a 92 928S4 and a 76 911S track car. If you have any questions, feel free to ask me!

If your control panel looks like this, I pushed and held each button for 10 seconds starting with the top left and working to my right bottom. On mine it was the ‘End of Cycle Signal” button. How I did this was, to first unplug it for 5 min (didn’t work) Then, push a single button at 1 time for 10 seconds and hit the pink cancel button 1 time between each new button. until it works or if it hadn’t , My plan was to begin pushing 2 at a time in a logical order. It won’t let me post the pictures, sorry.
