For BMW electrical system diagnosis service may trust our trained technicians and advanced equipment to troubleshoot the highly complex BMW electrical system in your BMW. We will load test your BMW’s electrical system and measure it against factory standards. In addition to checking for corrosion and loose connections, we also measure circuit loads, drops, and conduct variable circuit load testing—the only way to fully ensure proper functioning of your electrical system.
Your BMW’s electrical system typically operates at 80-100% capacity, which means there is no room for even small voltage variations that could impact the performance of computerized controls. Most problems BMW owners see in day-to-day driving are caused by small voltage issues.
