My AC stopped working when car was low on fuel
I haVe a 2001 S600 w/58K on the odometer. I was driving home this weekend when my AC just stopped working. The EC light stays on, and I can't get it to let the AC run. I took it to a shop today and had the pressure checked. He said there was plenty R-134 in the system.
I know the car goes into EC mode when it runs low on fuel. That's what happened to me; I wanted to get gas at a station I have an account with, so I let it run a little more than halfway down the reserve section. I read int he manual that the Climate Control goes into EC mode to conserve fuel, btu I thought it would reset iftself automatically. What else could I have done to cause this?
How do I get the AC to reset? Is there a trick that I couldn't find in the manual? I have an appointment at the Dealership, but I really don't want to have to pay for the dealer to service this, unless I have to.
Has this ever happened to anyone else.

I have never heard of these cars turning off the AC when it is low on fuel.. If that was the case mine would never work unless it's specific to the 600 which gives me yet another reason not to get one.
I think (hope ) you have something else wrong.. the dealer would know. Unless it's a benz shop with Star Diag., then you can get 100 wrong answers
about the functionality of the AC program on these cars..
My AC off light came on for no reason earlier this year and it took the dealer to hook up and reset it for me. I haven't had any issues since.
Imagine me living in Tx and running low on fuel in the middle of the day, and my AC goes off.. I'd NOT be driving this car for long that's for sure...

Once the AC fault code is set it must be cleared with the Star to get the compressor to run again and extinguish the EC led...
Probly a pound low on 134.. The system should be checked for leakes and the system evacuated and recharged to the correct charge after the fault code is cleared..
