E350 CDI Avantgarde - 2010
Blind spot assist false warnings (red triangle)
Bought a W212 E350cdi - 2010 a few months ago and have had problems with the blind spot assistance a few months back.
On the passenger side, the radar sensor warns that there is something in the blind spot even though it is empty there.
Either a little sporadic flashing or persistent for a few seconds to work flawlessly for a period of time.
Does not seem to provoke the error in any way, nothing I have succeeded in.
EDIT: This past week the error have occured more frequently. Especially in the morning when the car havent been used over night.
What I have done is:
Take down the sensors from the rear spoiler, checked for dirty and mudd.
Switched side of the sensors to exclude if the fault occurs on the driver's side.
Checked for corrosion in the connectors on the sensor.
The error persists and always on the passenger side even though I switched sides on the sensors.
Have someone had the same problem and how did you solve it?

Did not have the problem yet (knock on the wood) but read a lot about corrosion on radars making lot of troubles.
In your case you already check it, so I think you will not go any farther without a scanner.

Is it possible to obtain part numbers on the wiering harness through a website
to the radarsensor.
I have a feeling that it is the cable harness itself that is causing trouble. Read a lot about problems with the cabel harness.

Depends on the scanner you will have different options.
When any MB-oriented scanner will show you pending code, who did not show in dashboard (yet) some scanners will let you check the connections and do adaptations.
I have iCarsoft MBII and MaxiEcu and between those 2 can do almost everything on chassis, but still waiting for more programs for OM651 engine.
