2002 C230 coupe, 95,000 miles
Check engine light came on.
Local mechanic told my daughter she needs a new supercharger.
I don't have any other details right now.
I'll look into it to be sure that this is truly the case.

My question is can this be a DIY?
I'm pretty good around the garage and if it's just a matter of unbolting and rebolting things I could certainly do it.

Thanks, Dan

MB supercharger failures are extremely rare. What fault codes were found?

Not quite the same, but when the turbo on the wife's Volvo blew a seal and sent oil everywhere, out independent who is a good personal friend told me that it was do-able, but a little finicky to get it just right. Suggested that he do the job rather than I, and I let him go at it. Not cheap.

But as the previous poster noted, I'd want a careful reasonable discussion that convinced ME that the blower was indeed, in fact, and really actually the problem.

Thanks for the inputs.
I don't have the codes yet. I'll post them when my daughter brings them over.
I won't procede with this repair unless I am certain the supercharger is the culprit.

I talked to the mechanic.
He didn't have the code numbers but the descriptions were:
"Secondary air malfunction" and "Secondary air too low".
On the estimate is written, "Found supercharger has insufficient performance and is loud".

Could be a leaky gasket somewhere?
Can I tell anything by pulling the belt and turning the SC pulley by hand?

The supercharger does double-duty on this car, in addition to being used in the standard fashion as a supercharger it is also used as an air pump for the secondary air-injection system. There are a series of diverter-flaps and switchover valves that accomplish this task, a malfunction in any of these devices can cause the codes your mechanic reported.

In addition a weak O2 sensor or a plugged line in the air injection tubing has also been know to trigger this code.

I'd like to know a whole lot more about exactly what was done to determine the supercharger is at fault, there are a whole lot of other things that are more likely to cause this code (P0410 I think?)

Do a search for 'P0410 + C230' for more info.

There's always the option of putting black tape over the Check Engine light.
