Same day car diagnostics with scanner (Ventura)

Mechanics are often days or weeks out, especially around the holidays.
I do same day diagnostics by plugging a scanner in, which gives a code and the severity of the problem.
I can drive to you and charge $20 per scanner reading.
Sometimes it’s as simple as a filter change or oil change, or it could be a bad sensor or pump.
It’s better to know then decide where to source the part and who to hire to repair it.
