SC Question
Happy Sunday fellas:
This morning (pouring rain, about 45-50F) I cold-started my car, drove about two hundreds yards to the end of my street and thought the car was not running as usual. I turned onto the main road and punched it and quickly realized the SC was not humming. I punched it a few times and thought to myself that I am glad i didn't buy a C320. After a half mile I pulled over, turned the car off and then restarted and everything was fine. I drove around, ran errands, shut the car off and on a number of times during the course of the day and the issue never resurfaced.
Has anyone experienced this type of isolated SC failure? I have read stories of intermittent SC engage-disengagement, etc., and know about SC pump failure. Any suggestions? Is there a simple way to troubleshoot the SC, pump, etc.?
Thanks

its the pump. the easiest way to diagnose the pump is the next time it shuts down reach inside the door in the pass fenderwell and feel the pump it should be running . if not its toast.
btw the c320 runs much better than a c32 without the s/c!!

Thanks for the feedback. That is exactly what I was thinking. I thought it was strange I had no SC on a cold start then drove .5 mi, stopped, restarted and everything was fine. I was wondering if it may have been a one time phenomenon??
So where is the IC pump located? Are we talking inside the passenger's side wheel well area or inside the engine bay?

my i/c pump was an electrical failure. the windings in the pump were burnt so contacts were being broken. pump would fail hot or cold
pump is under the fenderwell panel on pass side

Replaced my I/C pump and the S/C hasn't skipped a beat.

I guess I am the only one that would disagree with that problem being a intercooler pump. Starting a car up in 40 degree weather and driving it for 200 yards would not be long enough for a IC pump to be a problem. If it were 100 degree temps I don't think the intercooler water would be hot enough to shut down the SC after only 200 yards.
I would think that it might be some intermittent sensor or SC clutch issue if it reset itself after turning the car off then on.

just as an example within 1/4 mile the temps can go from 40*C to 80*C with a normal acceleration. s/c heats up very quickly
