Service Details
European Vehicle Electrical Diagnostics in Medford, Oregon
European cars have some of the most complex electrical systems on the road. A single BMW 5 Series can have over 80 electronic control modules communicating on multiple data networks. When something goes wrong, a generic code reader from the parts store won't give you the full picture. You need manufacturer-specific tools and someone who knows how to interpret the data.
At NW Autohaus, we run full system scans that read every module in the vehicle, not just the engine. That means we can catch faults in your comfort module, gateway, body control unit, and other systems that generic scanners miss entirely. We also perform live data monitoring, actuator testing, and guided fault finding.
Electrical problems can cause everything from a check engine light to intermittent starting issues, phantom warning messages, and battery drain. If your car is acting strange and no one can figure out why, bring it to us.

“Audi owner here that always used the dealership for service. NW Autohaus gave my Audi amazing service and went over everything like the dealership would. Jason put the diagnostic machine on my Audi to find out what the idiot light on the dash was about. Very pleased with the service and the price.”

“I called BMW and they quoted me $2500 and told me all this stuff was wrong with the car. Brought it to Autohaus and these guys fixed it for a fraction of the cost in a fraction of the time. Honest, hardworking, and they genuinely care about their customers.”

“Chris is a really unique mechanic. Rarely do you find a guy who both truly loves cars and is detailed enough to tackle complicated repairs. He took on a project of doing the timing chain service for the infamous Audi 4.2L V8. I wouldn't trust anyone else with it.”
