I took my s55 for a drive today and from a complete stop without traction control and with traction control I get the same results, it will not spin the tires! I've tried it in drive sport and in 1st manual! I've done ecu reset and still same result! I floor it and it doesn't rev, it just pulls off sluggishly. Don't know how long it's been that way but before I could smokem pretty good! What could this be?

Is the intercooler system full of coolant?
is the intercooler pump working?
Is the supercharger clutch engaging?
Is the transmission nproperly topped-up?

Sounds to me like no power from the supercharger, so it's acting like a basic V8. I'd start with the supercharger clutch, since that's a known item.

Intercooler pump is working great!How do you check to see if clutch is engaging? Transmission topped off?

Have you scanned the car for codes? If not, you should start there. Otherwise, with the car in park and running with the hood up, have a friend bring up the rpm and see if the supercharger pulley spins any faster than with low rpm.

Depending upon the mileage of the car, the transmission fluid should be changed; not simply topped off. Consider this an every 5 year, 50k mile service, more frequently if you drive it hard (which, if you're TRYING to spin the tires, I suspect you do).

Or, you can take it to an experienced indy and let them deal smartly with it.

The clutch assembly is barely moving, it moves a little faster at higher rpm! Where can I find a replacement clutch assembly?
