Car would crank but wouldn't start intermittently. Beginning yesterday, the car (mind you a 1999 clk 320 with only 75k miles) engine would cut out whilst i was driving. First time, the car died in a busy parking lot and the second time, in the middle of the street! I had to get out and push it out of the way of traffic.

Not sure if the item below was the cause, but it sure is suspicious as it was the only change made recently...

"- You should have the defective sensors replaced. But in the interrim, follow these instructions to override the sensor. (Your A/C compressor has its own pressure switch, so overriding the 'EC' light will not compromise this safeguard.) Switch the ignition on (position 2). Set the left temperature to 'HI' and the right temperature to 'LO'. Switch the ignition off. While holding the 'REST' button, switch the ignition on (position 2). On the left side, 'P1' will flash and on the right side, a code will be displayed. Press the 'EC' button twice so that the left side flashes 'P2'. Using the right side red temperature increase button, add 16 to the value. Press the 'EC button again to store the updated code. Turn the ignition off. "

Code fixed my a/c fine, but if it comes at the risk of cutting out my engine, then maybe i'll just stick with the rolled down windows! Anyone have any thoughts on this, could my problem be related, or do I also have one of the fuel or OVP relays that they talk about elsewhere in the forum.

I rolled back the change and will see how it goes today, but it sure sucks to have to push your mercedes down the street!!!
