ECU Fuse Keeps Blowing after Trackday - No CEL - TT

You have an intermittent short. Grab the schematic and see what that fuse runs. Then, start tracing from there. Is your grommit behind the battery that feeds the main engine

Then, start tracing from there. Is your grommit behind the battery that feeds the main engine harness into the interior in good shape. Wondering if you have a water intrusion issue where water has gotten to the ECU and damaged it. Check your ECU connectors for any signs of green corrosion. Rusty likes this.
