I have a 1998 E320 Mercedes Benz. It has been sitting for about 3 weeks. I went to take it out for a drive this morning and NO START!! I put the key in and it beeps and when I turn the key I just hear a click. I have lights, radio, windows go up and down, could this still be a battery problem?? What do you think???

 

Check battery voltage.

You can check it using the CCU to get a general feel for where it is at. Key to pos 2, press and hold REST for 5 secs, use AUTO buttons to toggle to screen 23.

 

You can have full headlights in a w210 and not have enough to start the car.
Start there.

10amps overnight,key out,use the charging post under the hood.

 

I'm having a similar problem with a 2000 E320 4Matic. I checked the battery and it is okay. Here's the problem...you can crank the car cold but after it has run a little it will
not restart. It will turn the starter just fine but not start. If you let it cool down for a while it will crank okay...Is this an oxygen sensor problem?

Hello, All
I have a 2000 E320 with over 205,000 miles in southern California. Car recently started hesitating and dying at stops. Now engine cranks, but won't start (it previously started if I let it sit overnight).

Codes shown are P010 (MAF-Mass Air Flow Sensor),*
P0306, P0305. P0304, P0300 (misfires),
P0110 (IAT-Intake Air Temp Sensor) and*
P0700 (Transmission).

Since earlier I was able to start using ether starting fluid, I replaced fuel filter. Ran fine for over 1,000 miles, then problem worsened.
I cleaned MAF (Thanks for DIY.) It started, ran better w/o hesitation about 10 min, then died again. (2nd ride home on tow truck.)

Suggestions appreciated (Crankshaft Position Sensor?)

Thanks for your response, Plutoe.
Codes I listed are total codes in the computer. I just bought the OBD2 CReaderV and have not yet reset any codes.
I have no idea how long codes have been in system. Check engine light just came on recently.

 

By the codes you have it sounds like a maf failure. Get oem or bosch , you can find a good used one on ebay

 

Thanks, MOTOJAE.

 

I have an e420. It's been sitting for 8 months. I bought a new battery and added 2.5 gallons of gas (the first time i tried starting I didn't realize the gas was empty) Still no start It sounds like it's about to start! I hear everything it just wont fully turn I tried stepping on the gas a little and still. What do you guys think is wrong? Should I add more gas?

 

Would my key fob be a problem? I think there's no battery inside. It fell apart a few weeks ago when I dropped it. I have the old box key with the flat blade. (one button) 97' e420

 

Hmm i'm going to try to put it into the almost on position and then off back and forth 10x then finally all the way on. Maybe that'll help? >.<

 

i got new key fob batteries, i tried cranking it 20 times! it doesn't want to turn on i don't get it. is my fuel pump dead?

 

freeze frame data? I just don't have time. Should I just call Mercedes roadside? Or is that a stupid stealership idea? ahahah. Man what happened to good battery, good starter, good gas and you're good to go? ahahaha

 

I was actually thinking about a c6 vette

 

but i have so many memories with this car I still want it =0(
