Schedule a computer diagnostic at the first sign of a dashboard warning light, unusual noise, or drop in performance—catching issues early can prevent costly repairs later.

Schedule a diagnostic check if you notice:

• Check-engine, ABS, TPMS, or other warning lights illuminated
• Decrease in fuel efficiency or engine power
• Emissions test or inspection failure
• Rough idling, stalling, or slow acceleration
• Difficulty starting or unexpected battery drain
• Unusual knocks, rattles, or squeaks from under the hood or chassis

Wilhelm Automotive recommends a full diagnostic scan at least once a year during routine maintenance or whenever a new warning light appears.
