*Fix Solved* ML320 ML350 ML430 ML500 W163 starting issues or kill switch issue.

I have a 1999 ML320 that had a starting issue. It would start and then turn off after about 1 second. It would do this repeatedly. Sometimes it would never turn on. Thanks to 43SQD from benzworld, i found a solution. It is a bad key sensor on the ignition. It is not sending a proper reading of the key and kills ignition in the car.

I went to my junk yard and found a 1999 ML 320 and a 2003 ML430. Pulled the parts from both. The 2003 had a differe t part number and fit right in. I used the newer part even though it had a different part number because it was newer. My ML now starts like a charm.

It took about 15 minutes to complete. Thanks for watching

Thank-you for sharing, great help that save people money. Some dealerships charge thousands by coming up with different associated (fabricated faults).

Watching 4 years later and have almost the same mileage on an 03. About 20 miles apart.

Thank you for sharing. I have had this problem for a couple of years. And the dealer told me to scrap the car?
It would be nice to go out on the road again.

I have the same problem. In the past I changed keys and the problem got fixed. This time the key are in the back order and considering trying your method. Before you resolved it, did the security light on the dashboard blink while you had the key in the ignition? Did the security system recognize your key?

The correct name for the part is transponder immobilizer not kill switch or ignition switch they are different

Thank you!!!! I am having the exact same problem I have had it five different mechanics no not the Mercedes dealer I didn’t want to be left out for taking the 1999 into Mercedes 🤣🤦🏼‍♀️. No one could figure out what was wrong and help me 🤬

An absolute ridiculous question I’m sure 🤦🏼‍♀️. But I have sound that win the car temperature is at least 85° I have no issues with it starting. I have went as far as to buy a space heater and put it in front of the Mercedes in the garage to keep the car warm in the winter. Thank goodness I live in Phoenix and it’s warm enough about eight months of the year. When Alex at least 45° in the car starts no problem it’s only when the car is called that it will not start???

And when it doesn’t start what does exact same thing yours does. Starts up ones for two seconds and then dies.

Could this be the same problem you were having?

Does the immobilizer need to be programmed with the key fob? If so, how?

Hi, I have 2003 ML500. I open the door, car comes to life? All warning lights on dash, cabin fan motor on, start error on led odometer. I remove a relay under the hood, a bunch of times, maybe it goes back to “normal” or wait 1/2 hour and then normal. Start up & drive away. Works fine rest of the day. Then tomorrow maybe normal or maybe repeat.
I have $3K of dealer & independent Merc guy, can’t fix it? Any ideas? Thanks

Thanks for the great video. I was just wondering, I have a mb ml350 2004 and every time I start it..it always has a false start then I have to wait and start it again and it starts right up. If I stop for maybe 10 mins it doesn't have the false start. But for maybe over 30mins stops it will do that. Do you think it might be my key ignition sensor (key transponder immobilizer) or maybe the gas pump is not pulling enough gas to help it start on the 1st try? Thanks!

Did you change the invention tumbler? Did you get it program? Abou how much you paid for the parts?

[amarie_love]

Do you know what the piece you pulled is called? So I can order one..

[stevedelisle]

Does the original key work? Or did you have to get the key for the new part from the junkyard?

[catnap-y-sm]

so i have a ml 430 2001. my runs but then when i step on the accelerator it does get it so i have to turn it off and turn it back on so it to get the gas pedal do you know what could it be

[zeusollldd]

I replaced the sensor with another one and it’s doing the same the problem.
What else you think can be the problem ?

[dimopetrov]

Thank you very much! I hope my problem is the same. How much it cost that part from the junkyard, I found it on eBay for $95 free shipping. Do you think is good deal? Thanks!

[carlosbeltran]

Did you get any codes before you changed out the sensor?
