Hello,
I am new to MB. I have a "hood warning " on board but the hood is closed. My MB asked for $700 to fix it. I d like to locate the hood sensor to stop the noise in the car( it is driving me Crazy )
Thx for your help
Welcome to MBWorld. Stupid question, but you tried slamming the hood shut right? w204 actually has two latches for the hood and we've had people come on before and ask similar questions as you have with regards to the hood sensor and they find out that it just wasn't latched properly. Gravity isn't enough with that hood.
Hello,
Yeah I have tried several time. When I Went to my dealer He claimed that the several peaces including the latches need to be changed ( but the Hood is shut And secure) then "taped" the sensor (where is it) to temporary stop the noise before I can bring back the car to change the latches. The noise stop for one day. Then restart. I guess the tape holding the sensor should be gone (weather) And I want to do before i can bring the car to repair. Problem where is the sensor ? Thank you for your help

Actually it is super easy to fix. The part costs about $20 on eBay. I fixed it myself on my 2008 C300.
The hood sensor is on the driver's side. It envelops the latch catch. But the whole thing is covered by a plastic panel. So this needs to be removed first. The plastic panel cover is held down by 2 pin fasteners, which can be pulled up by a pair of pliers. Then use a flat head to remove the rest of the fastener.
Use appropriate metric wrench to remove the 2 bolts holding the latch catch. At this point, the latch catch assembly can be taken into your hand. Gently pull and remove the sensor cable. The hood sensor is actually a cover for the latch catch. Using a flat head, pry open the hood sensor. The reason for the failure generally is a metal strip that goes soft. This wire pushes down the actual switch. When the metal strip goes soft, it does not push down the switch anymore.
When I got the new switch on eBay, it did not work on the first try. So I had to bend the metal strip a bit to get it to work. Pictures attached. Due to some weird reason, they get attached upside down.
Time taken: 40 mins. Cost of replacement part: $20
