I took my E300TD Mercedes to Oswalt's Car Repair to diagnostic check engine light.Two weeks & $700.00 later and $300.00 more requested, no parts purchased : light still on. Professional jargon and experience of Mike Oswalt fooled even an old gear head like me. Mercedes diaqnostic of same problem $165.00. Do not leave your car with Mike Oswalt if you do not know exactly what the problem is. I sincerely urge you to take caution.
