Hey fella's

Just got a 04 E55 5 days ago and need to take it back to the dealer. Anyone have any idea what this could be? So bummed right now. Love the car and better not have to pay for this fix. No warranty on the car, but just got it and feel the dealer should take care of this problem.

Any idea's?
Thank

slipping in 2nd = tranny issue
my S/C makes the whistling sound also.

Can someone describe what it feels like to "slip in 2nd"?

FYI, in NY and, I believe, a lot of other states, it is mandatory for every used car dealer to provide a short term (usually 1 month/3,000mi) warranty on every vehicle sold. Check the laws in your state, but even if the law doesn't apply, a reputable car dealer should work with you, especially if it was within 2 days of taking delivery of the car.

what do u mean by slipping ? like chorking ?
or like

power comes and goes, comes and goes in a fast way that you feel like you have a plugs problem ?

explain more please

that happens sometimes there is no need to take it in to the dealer, but since you just bought it take it back, and make sure they pay for it. But all you need to do is reset the ecu, if you search the forums you can find posts on how to do this simple reset it will definitely fix ur problem.

I believe it's the supercharger clutch engaging. Is it a whistling or a chirping sound?

that is what I think too. Mine does chirp and jerk and this is totally normal as that is the blower engaging

now if the car revs up and you are going now where, that would be a slipping issue.

It's probably the s/c clutch mine was doing the same thing, a chirp/whistle sound when going into 2nd with my foot into it. MB told me there was a bulletin or something about the noise. That's why i had that loaner when i came by.

engine jerk is not slipping.. just SC engaging.

if you upgrade pulley.. you will feel even bigger jolts.

Start by changing the belt and if the its still very loud.. then do the idler pulley. Since you are new.. search for the write ups.

Don't worry.. your car is fine.. don't need to switch to the new pulley if you don't have warranty.

BTW: I have the new pulley since I got it replaced by the dealer.. and i still have the chirp, but not as jerky as the original one.

quick question on this. if the power comes and goes in a fast way, do you think it's a plug problem?

mine does this in third/forth/fifth gear pulls on the highway during aggressive throttle

Agree with the guys above. Supercharger engage can be quite rough and not what people are expecting when in a Mercedes.

You should try it with a few mods, you can feel your organs moving around.

Thanks guys, for all your reply's. I will be taking the car back to have them look at it. This gives me something to show the dealer. It was not a Benz dealership, So I hope they will take care of it for me...
