We'll take you along on the troubleshooting journey – from diagnosing the ECU to uncovering the dark secrets this US import hides beneath its pristine exterior. What you can expect in this video: Troubleshooting to the extreme: Why simply replacing the recirculation flap wasn't enough. US imports & their pitfalls: We reveal what's really going on under the hood (keyword: accident repairs & wiring harness chaos).
