Our Technicians Have Recommended Diagnostic Testing To Accurately Identify The Cause Of Your Vehicle's Concern. You Have Chosen To Decline This Testing. Please Understand: Without Proper Diagnosis, Any Repair Performed Is Based On Best-Guess Or Your Direction Rather Than Confirmed Findings. This Means The Repair May Not Resolve Your Concern, Additional Parts And Labor May Be Required Once The True Cause Is Found, And Parts Installed Based On A Guess Are Not Refundable. Gearhead Automotive Services Ltd. Is Not Responsible For Misdiagnosis Or Unresolved Concerns Resulting From Declined Diagnostic Testing.
