Unhappy Some problems.......

Hey guys, I'm at a loss here with my car. The Supercharger feels like it just shuts off at 3800 rpm and it is running off just the motor. Also I'm having a intermittent antifreeze leak coming from the back of the engine block......I have looked and can't find where it is coming from.

Could the supercharger clutch shims need to be redone, or do I have another problem going on?

Is there a coolant line that runs to the back of the intercooler that I 'm not seeing?

Any help is appreciated. I'm half temped to sell it like it is and cut my losses.

Hmmm...Good question. I wish I could be of help. Mine hasn't gave me much problems so I haven't had to tear into it much.

How many miles do you have? I would personally think it wouldn't be leaking from this area, but I haven't heard either way if this is a common problem or not.

I just put mine on cars.com today so I know how it is.

It may just be your intercooler pump, as that is a very commom loss of power.

Any codes, can you feel it engage and then it shuts off?

You have two coolant lines running to the intercooler. Do you have good power when cold engine?

I don't have a code reader.......I can feel it engage right off the bat, then at about 3800-4000 it just stops pulling, feels like all boost pressure is lost.

Speedriven1, it happens even on a cold engine.

No updates.....been working too much to save some money to fix it. I just want to sell it not do to the fact that it's broke, it was an impulse buy for me. Just ready to move on.

Same for me..I get bored of cars way too easily. I'm thinking something other than Mercedes this time. I'm thinking it's time for an Audi
