Mobile & Shop Diagnostics

Dealer-level diagnostics at your driveway. If it needs heavy surgery, we take it to our shop.

A Check Engine Light isn't just an annoyance; it's a warning. Instead of guessing with cheap parts or paying for a tow truck just to find out what's wrong, call 4W Solutions.

We bring dealer-level scanners and diagnostic tools directly to your vehicle. We pinpoint the issue—whether it's a complex electrical gremlin or a simple sensor failure—right where it sits. If the repair is too big for the driveway, we can transport your vehicle to our dedicated repair facility in Billings to get the job done right.

    Seamless Repair Process
