My 2015 7R is throwing up tyre pressure light abs light and traction light, ACC and front assist not available, cornering light error, hill hold assist but when I got the car scanned it was saying all 4 wheel speed sensors and timing was over advanced I got the timing replaced and my mechanic checked the wheel speed sensor areas and said there was dirt and rust which he cleaned to the best of his ability and the issue was gone for maybe 100 miles but now it’s back and it’s also doing something new throwing up flashing traction sign and cutting power when I use the throttle sometimes, all the lights are intermittent aswell come and go sometimes stay for a while please this is doing my head in I need help I’ll attach some images
