Blind Spot Detection Inoperative
Our 2013 GLK 250 has this as its only problem. It seems that there is a intermittant problem to a degree as it seems to pass the check on start up sometimes and then goes to fail mode where the yellow triangles stay lit in the mirrors after a short distance. I have turned it off for now but has anyone had this issue and what generally had been the cause and rectification. My wife called the dealer and was told that it is a 1.5 hr diagnostic plus 4 to 5 hours to fix. This seems extreme when the diagnostics have been done and it is either of 2 transducers / radar buds in the back bumper that need to be replaced. Is there a separate radar unit in the rear bumper area as well as the backup sensor buds? Any past experience as to cause and fi would be appreciated. I am in Canada with lots of cold and snow/salt and slush but I washed up the vehicle yesterday and that did not improve things.
Thanks GLKers

So there are two radar sensor modules in the rear bumper. The module part number is 000-905-01-10, see if it got damaged or unpluged. The wiring could also have been damaged.

Blind Spot Radar Sensors Replaced
It would seem that there is am unofficial recall in Canada. The radar detectors on each side of the rear bumper and the wiring harness between all the sensors was replaced at no charge. Thank goodness for Mercedes standing behind their designs which in this case involved corrosion in the connectors due to the heavy use of salt during winter. They also put in a cover of sorts to prevent salt and snow from packing into this area where the radar detectors are located. Thus a known problem in Canada due to design defficiency.. Vehicle is 2013 and off warrenty..

They did replace both radar sensors and the wiring harness between all the bumper units including the rear parktronic sensors.as the particular diagnosis was corrosion at the pins.
Good luck with your repair.

There is no number for a recall on my receipt. In fact it is a repair oder piece of paper and not the usual one that you get when the service intervals are completed which list manhours etc. The service manager advised me that Mercedes will make the call but it is likely that this will be free. I doubt that he would have made this statement if he was not sure of the outcome from Mercedes. They kept the car overnight and the next day it was done and free even though the car is off warrenty. It has low mileage but I do not know what the criteria is other than being in Canada with all the corrosion from salt.

I had the same repair done last winter. Yesterday it broke again. I've been really happy with the vehicle, but i'm getting worried now. The extended warranty runs out in 20,000km and if this is a yearly event it'll drive me nuts. Maybe some dialectic grease will help. I guess i'd better book it back in.

Are you the original owner of your vehicle?

Hello, I am located in Western Canada, own a 2015 GLK350 with the blind spot assist issue, but I am not the original owner, not sure if MB will be very generous. I removed the sensors from the brackets today, and cleaned the white surface, I guess I should have removed the harness, and checked for corrosion at the connections. Warning lights are still on at this time.

I had the dealer replace these for me. There is no recall. Mercedes Canada has been approving request to replace them in kind. There is a manufacturing defect in the original sensor. Apparently the adhesive that holds it together fails and lets water in causing the sensor to fail. The new sensors use a different adhesive, an updated gasket and they submerge the internals in Gel. You would have to go to your local dealer and ask them to apply to Mercedes Canada to have them replaced. I think they look for customer loyalty to approve request (not sure about this). I quoted all the Mercedes i owned in the past and my regular use of the dealer service department. They asked me for the car mileage as well. It was approved in 24 hours. The cost to replace them is roughly 2500 dollars Canadian. I paid 0 dollars.

Great outcome. A little worried on why the front wheel bearings needed changing.

I also live in Edmonton and my 2013 GLK 350 is having the same issue with radar sensor. Please can you tell me how should I handle this issue with Mercedes? What should I tell them?
I really want to repair that free of charge as I don't really want to spend $2,500.
Thanks in advance.

Hi Wespart
If you look at my original comment above. It tells you exactly what to say to the dealership.
" You would have to go to your local dealer and ask them to apply to Mercedes Canada to have them replaced. I think they look for customer loyalty to approve request (not sure about this).

Hi Ramo80,
Thank you very much for your reply. I called the dealership today and they said they need to diagnostic the vehicle first before they can make a statement saying that it will be covered by Mercedes. However in case Mercedes won't cover it, I will need to pay for the diagnostic fee, which can cost up to $400. I'm bringing the vehicle in on Thursday and I'm crossing my fingers that is a manufacturing defect, so they won't charge me.

Be forewarned that it’s not likely to be a manufacturer defect, and that you’ll likely have to pay.
#23
I brought the vehicle to the dealership this morning and 2 hours later they sent me a quote of about $2,500. On the quote it is mentioned that both blindspot sensors and wiring harness are corroded. This should be covered by MB, but they want to charge me for that. I read many posts where people are saying that the reason of the free replacement by MB was the corrosion. I'm waiting to talk to the service department.
Any advice?

Got my blind spot sensors fixed free
Just had my sensors replaced and s/w upgraded along with 2 recalls (steering wheel bolts and airbag ground wire) for free on a used 2013 GLK 350. It’s a known corrosion issue and MB stands behind it. Road salt really does a job here in Ontario. Had the same issue on a 2013 C300. Fixed for free too.
Can’t believe the top level of service I always receive at Star Motors of Ottawa. They are the reason this is my 6th MB! That’s why I’m a lifetime customer now
