I have a very loud whining noise in the engine that people can hear me coming home. I have had a automatic transmission specialist look at the trans and he said not the transmission. I have taken the serpentine belt off and and noise is still there. Has anyone had this problem before and if so found out what it was or is.

I think you might be confused, C230 has a straight 4, not a V6.

Also are there any other symptoms other than the noise?

My car is a 2006 C230. No other symptoms....Just the whinning when serpentine belt removed

C280 Sport

The C230 in 2006 and 2007 was a N/A V6 201bhp engine. The 4 Cylinder with the Supercharger was from 2002-2005.

I know my car is a 2006 C230 V6. I just did not know how this site listing worked. As I said I am new to this.
the noise is not from transmission and continues with the serpentine belt off. I am only wanting to know if anyone else has come across this problem and if it is worth spending money on repair or just wreck the car. The milage is just at 100,000kms.
