Both Blind Spot Sensors
Replacement parts from MB (I beleive # 0009050110) are crazy expensive.
Has anyone tried to fix these sensors?
Any cheaper after market parts which will do the job?
Thanks




I'm in Canada, where they use a lot of abrasive products on the road during winter.




aftermarket unlikely available...

You'll need a new "bumper harness" either front or rear.
Everybody else.... SILICONE RTV all your electrical connectors before water soaks passed defective harness seals.
Many available candidates:
- All 5x radar modules !!
- (Bumper parking sensors ? - Don't have)
- ISM selector $$$$
- Steering rack $$$$
- Ambient temp sensor !
- Rear bumber trunk kick sensor !
- (ABS sensors are A-OK!)
- A/C Compressor hookups !!
- Condenser Pressure sensor !!
When it poors... no problem.

I had to replace mine on the passenger side and I first ordered one from eBay but it did not work. Then ordered one from a dealer for the crazy price and it is plug-and-play working as new.




I recommend everyone buy a Mercedes specific OBD scanner so they can try and look for the issues themselves. I'm interested in what the scanner is showing for faults with the sensors.
The inexpensive Launch creader obd scanner seems to be capable for most.

Theres alot on ebay being sold as refurbished/remanufactured. Wonder if thats true or just selling clones.
I would give a shot at fixing them. Remove and inspect them for water getting in. May even be a bad connection.

Absolutely smart computer stunt over CAN-Bus.
It doesn't "just beeps"... car actively reacts to preserve distances front / sides / back.
OMG - Feature pays for itself.

These bumper modules are setup to get swamped by rain projections...The enclosure seam is two hot-melted half-shells.
Harness connector is too cheap!!

I doubt any scanner can connect with a ghosted module.
New harness necessary as shown in eBay listing.
