2004 Mercedes E320 Station Wagon RWD

This 2004 Black Mercedes E320 Wagon is my daily driver.
It has been recently serviced by Mercedes Benz of Buffalo. It received a rear parking brake adjustment and a new fuel tank under an extended warranty.
Recent repairs/work completed:
- New engine air filter- Front lower control arms and bushings- Engine Mounts- Transmission Mount- New Headlamps and bulbs- 8 Quarts of Mobile European Oil changed in August 2016- NewAuxiliaryand Main Battery in July and August respectively- Crankshaft Position Sensor
The driver-side door panel has a slight crease in it from apreviousowner'swife rubbing it in a garage, but it follows thecurvatureof the door so closely it's barelynoticeable. The rear driver-side quarter panel has beenrepairedby a previous owner. This does not appear in Carfax, and I didn't realize it myself until I hand washed it and felt and heard the bondo.
Currently, even after a a full brake job last year, the "Brake, Service Workshop" message appears.
The brakes operate normally but I can hear the SBC pump coming on more often recently. I don't have a star multiplexer, so I can't check the SBC status.
The mileage might change a bit as it's my daily driver. This vehicle has been parked during winters and started it's life in California. There is virtually no rust on the body or chassis.
it still rides verycomfortablyand quietly, and the AC stills blows cold.
Any questions regarding the vehicle, just message me.
