2021 VW Tiguan: Blind Spot System Down
Since June, Jay’s Auto Repair in Wisconsin has turned to the IVS 360 Hotline 129 times — keeping tough jobs in-house and profit on the books.
1. THE CALL
At Prairie Autohaus Ltd. in Saskatoon, Canada, owner Yogi Thakore faced a tricky ADAS issue on a 2021 Volkswagen Tiguan. The shop reported that the lane change assistance warning lamps wouldn’t engage. Fault codes showed databus errors, open circuit warnings for the mirror lamp and a window regulator motor fault.
2. THE FIX
Our Master Tech, Anthony Khamly, connected with Yogi and walked through the diagnosis. He explained that when part of the blind spot monitoring system fails, it can bring down the entire ADAS system. Together, they reviewed the wiring diagram and isolated the suspect component: the two-pin connector behind the mirror glass. Anthony guided Yogi on performing an output test to verify signal voltage, and provided the step-by-step escalation if no signal was found — checking at the door connector, then at the blind spot module.
3. THE RESULT
Instead of chasing multiple fault codes across the vehicle, Prairie Autohaus narrowed the issue to a likely failed mirror glass or broken wire. The shop left with a precise diagnostic path, saving time, preventing unnecessary parts replacement and ensuring a confident repair plan.
🔧 MASTER TECH TIP
On Volkswagen Tiguan blind spot issues, remember: the system is only as strong as its weakest component. A single failed mirror glass or wiring break can take down the entire ADAS function — check the mirror glass connector first before replacing modules.
