Check Engine Light & Diagnostics

Diagnostics for European Cars in Roswell

Reading a code is only the start. We trace the code to its cause, and we explain what we find before any repair begins.

Check Engine Light Diagnostics

A steady light is usually less urgent than a flashing one. Either way, the code points to a system, not always to the part that failed.

We diagnose:

Check engine and other warning lights
Engine performance and misfire concerns
Sensor and emissions system faults
Transmission faults

Diagnostic tablet connected to a European car

Technician using a diagnostic tablet on a Mercedes

Electrical and Warning Light Diagnostics

Modern European cars depend on electronics. We test the systems behind the warning before we recommend a repair.

Electrical and battery drain problems
Suspension, steering and brake warnings
Drivetrain warning lights
Fuel system issues

 Trustindex verifies that the original source of the review is Google. Allen and the staff at Solo Motorsports completed a much needed overhaul of my BMW 335ci.  They always communicate clearly on the repair work they perform and go the extra mile. I highly recommend them!

 Trustindex verifies that the original source of the review is Google. Just had a stage 2 tune, TCM tune and downpipe install done to my 2024 M440i. First impressions car is a totally different animal. Car is pushing more power, better acceleration, and the transmission tune is chefs kiss. I dealt with Alen Muratovic in setting up the appointment, any questions I had were answered and then some. I was worried about over stress to components and I was assured they had my vehicles safety and longevity in mind. I’ll be back for a cooling system upgrade in the near future.
Edit: after a week with the car OH WOW!! Thanks Solo for making my already amazing car just that much better!!
