Proper Check Engine Light Diagnostics Can Save You Money!
Many drivers turn to auto parts stores for a quick scan when their check engine light comes on, often expecting a simple answer. These stores typically offer a free scan, but the results can be misleading. The code pulled from a scanner is just the beginning, and often, it’s only a guess about what the problem might be. Auto parts stores may suggest a part to replace based on this code, but this approach rarely addresses the root cause of the issue. Many times, it ends up costing more in the long-run!
The CAR Difference
At Certified Auto Repair of SLO, we are comprehensive with our diagnostics. We also offer free check engine light code scans, just like typical auto parts stores, but we can go a step further. If the problem is more complex or requires more diagnostics, we’ll advise you on further steps to ensure the correct repair is made, rather than just replacing parts based on an assumption.
