Check Engine Light On?

Not All Diagnostics Are Created Equal

Cars are more electronic than ever these days. You need answers from professionals who are well-versed in the ins and outs of contemporary car systems when that check engine light appears, not just a simple code scan.

With our Advanced Diagnostic Services, we provide just that.

We Solve Issues, Not Just Read Codes

After reading a fault code and plugging in a scanner, some auto shops let you leave. Diagnostics at our shop go far deeper. We take the time to thoroughly examine the systems in your car, identify the underlying issues, and offer precise, understandable fixes.

Regardless of what you’re dealing with:

• An unresponsive check engine light
• Sensor problems or electrical gremlins
• Complex trouble codes for European or BMW vehicles

BMW In-House Programming and Coding

You are likely well aware of how erratic diagnostics may be if you own a BMW. At K&M Automotive of Woodinville, we do all of the module or ECU programming in-house, unlike many shops that would contract with a third party.

• BMW coding and system reconfiguration
• Complete module and ECU programming 
• Factory-level diagnostic tools and software

Because your car will never leave our facility, you will benefit from a quicker turnaround, more accuracy, and increased peace of mind.
