After just having my C230K sedan for a week, the supercharger is acting up.

It is working intermittantly (not all the time). When the car is turned on in the mornings it makes strange noises which I was told is normal and the kompressor is spinning. Aswell when revving the engine up, it does kick in and spool up.

Now when driving its a different story. When you floor it from one stoplight it may or may not create the boost and give you that "kick".....if it doesnt it reaches redline slower than normal and basically is normally aspirated like a non kompressor 230.

Once you pull over and restart it will work for the first few times then not work anymore.

I thought it would be a possible MAS sensor but no check engine light is on or hesitation from the engine. So something is telling it the S/C not to come on....if the S/C was cooked then I dont think it would ever come on.

Where should I start looking? I dont race the car but I still want everything to work as should.

Please help.

did a search and read another posting similar....it read:

"took out the "Relay Module" box. Mostly all of the relays are contained in this box and soldered to a circuit board. Then I had to open it up and find were the K40 Relay was on the circuit board. Wasn't hard to find because there were two BAD solder joints for the K40. I re-soldered the connections and I haven't had a problem since."

Could this be my problem?

No need to use that on me when even newer cars like yours come with problems, too. Sorry I can't help, I have no SC input to share. Good luck, hopefully its nothing major

LOL Snibble....I guess we're even
