I've had my low mileage 05 Roadster now for a few years...and love it. Recently though I have 3 warning lights that are frustrating. The low coolant light remains on. I replaced the sensor and it remains on. Coolant level is fine. Likewise, the tire pressure light stays on. All 4 sensors have been checked and are fine, as are tire pressures. Finally, the BAS/ESP warning light is intermittent. I read the owner's manual on how to turn it off. That didn't work. It does as it pleases!

The local Chrysler dealership wants a $120 to diagnose these issues. Service manager admitted they don't have a Mercedes analyzer. Should I take it to a Mercedes dealer (90 miles)? Any advice would be appreciated.
