Volvo Engine Assessment in LA

I need an experienced mechanic to come to my location in downtown Los Angeles. My 2006 Volvo S40 has engine problems, with a "gargling" noise and a check engine light on. It broke down last week and will not start back up.

Ideal Skills and Experience:
- Experience with Volvo vehicles
- Expertise in diagnosing engine issues
- Ability to provide a detailed repair estimate and time frame
