Supercharger Problem: Does not work in cold weather
My car is a 2002 C230 6 speed.

I've never felt it loosing boost. I just turn on the car and the supercharger is either producing boost or it isn't...on or off.
I'll see what I can find.

I looked into what these mean, I know, not good.
I then took the car to another mechanic in the spring when the temp was above 20 degrees c consistently and asked that the check engine light be cleared and sure enough, it didn't come back on until the fall when the temp dropped again. That being said, I didn't know what to make of this, got frustrasted and continued to drive the car thinking when it dies, I'll just replace it as I was sick of sinking money into it without any answers. Now I already have another daily driver and want to keep my c230 (still running well and passing emissions at 371,xxx km) and do a restoration/drive it summers only. I'd like to get everything fixed.
That being said, it's going in the garage and I'm going to start looking at everything in detail.
One final comment, regarding the supercharger, something has to be causing the bypass to remain open when the temp drops...
I'll keep everyone posted on what I find.

After changing IC pump and check the fuse #5 and relay in the rear SAM, the supercharager still didn't work.
The engineer assume the rear SAM or front SAM have some problem but no error code beside (M44 IC pump power short ground etc...). The engineer add a relay between front fuse box (fuse of key start position) and IC pump using the wire directly to battery.
When the key is on ,the IC pump is started with battery power without pass through SAMs.
But the supercharager still wasn't worked.
Thanks God!
Finally , acoording the fuse chart in this site, I rechecked front and rear fuse #5, #7 #51(looked normal and exchanged with #49 the same amps) and #18 (there is NO relay on C and D in the rear SAM) in the fuse box and found my #18 fuse was broken.
After replace #18 (exchange with #5 7.5A) and all function runs well and got lose power back!
This result shows the SAM and FUSEs are different from years!
Thank you for who provide fuse chart in this side.
