Diesel and the smog check

Diesel vehicles 1998 and newer with a GVWR under 14,000 lb need a smog in California. The test is different from a gas car — it’s an OBD and visual inspection, and a lit check engine light fails it just the same. If the light is on, book the diagnostic first.

Diesel repair and diesel smog questions

Do you smog diesels?

Yes — diesel smog testing is available here. Call ahead with the year and model so we can confirm the test type.

Why is the diesel diagnostic $250?

Diesel diagnostics take longer and use specialized equipment. The $250 fee is not credited toward the repair.

Do you work on lifted or dually trucks?

Yes. Duallies and heavier trucks may have different pricing for inspections like the VSSI; call for a quote.
