Question Asked: Nothing happens when I turn the key in my E500 Wagon
November 18, 2010, 04:53 PM
Noticed this a few days ago... After sitting overnight, I got in and turned the key... Everything lit up fine (dash, display, etc.) but the car didn't make a sound. Turned it off and back on and it started.
I parked at the office and came out at 5pm and the same thing happened.
Over the next couple of days, I noticed it was more likely to happen when the car was cold or had been sitting for 6-7 hours.. A few times I had to try 3-4 times before it started. When the car's been running, it seems fine - no problems.
This leads me to believe I have a weak battery, but I get NO battery warning lights, no "consumer" messages, no dim lights - no other signs/symptoms
I replaced the battery today with a Bosch - simple swap and hope this resolves the problem.
If anyone thinks it might be something different, please let me know (hope not, the extended warranty just expired)
