So a few times today my car has been immobilized. The ignition lights up and engine turns over but wont start. When I remote lock the car and then re-enter a while later it will start. One time it left me stranded down the street. When I got home the engine stopped again. I then changed the battery in the Smart Key and hours later I got the car running. Hours after that it's not starting again. It’s been a frustrating day so far.
How do I cure this? Is there a specific procedure?

A few days ago, my 2001 E430 started doing exactly the same thing. The only thing that I can see is that our temperature and humidity has been extremely high over the last 4 days. I wonder if this is weather related. I am taking my Benz in to a dealership tomorrow and will kiip you posted as to what they find. If you could keep me in the loop as well that would be appreciated.

ok thanks Kirill. I appreciate the response and will also let you know what I find out. I wondered too if its temperature related but figured since it's always been a Texas car then it would have shown up before. New Smart Key arrives today hopefully and I'll see what difference that makes.

Can anyone tell me the following?

With the engine randomly cutting out several minutes from the house (IE sometimes I can make several small trips from the house with no problems), does this eliminate a smart key transponder problem since once the engine is started the transponder isn’t used? Or is this still a car security issue that comes into play?

I don't have a master key yet, but if I did would it still start the engine? Wondering if this test would eliminate it being a transponder problem or ECU type related problem.

 

Well, its solved.
Last night I changed the Crank Shaft Position Sensor (CPS) and now the car has been behaving properly. No more random "won't start". It appeared that the Texas heat after a shutdown the car would cause the failure in the sender. No OBDII code set as others have also said in the forums. $97 from the stealership for the part. 20 mins to change the part at home.

why are there so many Mercedes Forums? Time to combine them?? Searching all three is a pain
