Understanding the high depreciation on Mercedes Cars in the Electronic Era.
A single Parking Sensor ...one of six in the front bumper of C Class W204... Over $300 from Mercedes, the only source, as no after Market Part is compatible with the Vehicle Electronics.
The labour cost also high, as either Front or Rear Bumper has to be removed to replace. I hope to get it sorted by a local Specialist..
"Adams Auto Accessories".. he is currently negotiating to buy costly Test Equipment, which promises to allow after Market Sensors to be accepted by the Cars System.
