So after some mechanics worked on my car, I threw two codes.

One was the turbo waste gate solenoid, and the other was something about air injection.

I cleared them, and the supercharger started working for a bit, but then eventually the car always will throw the turbo waste gate solenoid code.

A member on here informed me to make sure everything was put back together correctly.

Sure enough, they had not put back a clip, but, after they got everything sealed correctly, the car keeps throwing this code, and now the supercharger does not shift on at all.

So, should I just replace the solenoid?

Any idea where it is?

I hope its just the solenoid that went out, and not some other crazy problem.

It really sucks driving without the top end power.

What year is the car?

The Supercharger on your car spins all the time & is not clutched like a C32. Boost pressure is controlled by the waste gate controller. It's obvious that the waste gate controller is not actuating. It is likely the solenoid.

Ok so replace do you think?

I have the cd and I can't find anything about this. I could find something about the limp home mode, and a few solenoids related to that, but nothing on this specific subject.

I'm guessing they only put some stuff on the cd, not all of it.

Ty for your responses.

You have the M111 right?

I'm 90% sure it's the actuator on the front of the engine. It's next to the air box attached to the oil catch can above the supercharger.

I replaced mine about 6 months ago.

First I would look up "recirculatory air flap" on this forum and find the thread on resetting it.

When you reset it, the flap should move. If it dosen't, you'll know for sure that's the problem.

OMG THank you!!! That worked and its fixed, AND it sounds better than ever before for some reason, LOLLLL!!!

Yea, mercedes calls it the recirculating air flap, not the name that the OBDII readers call it.

THANKS YALL!!!!!!

1) took off the manifold cover thing, 6 screws

2) vaccuumed out sand lol

3) looked in hole and pushed sprint loaded flap thing down twice until it stopped its self

4) started car for 15 seconds, off until car sounds like ti shuts down

5) started car 45 secods, off until it sounds like it shuts down

6) cleared P0243 code

7) drove around my block like a mad man woot woot!

M111

Edit: I wish it shifted faster though. I hate the hesitation.

Great news!

Okay I was just fooling myself into thinking it was fixed. I thought the power boost when it hit high RPM's was the supercharger, but it was not.

I do know that the actuator flap is working, because when I start the car, it closes for 20 seconds or so.

Also, when it gets to the point where the supercharger would kick in, it hesitates for a split second, and then resumes without the supercharger but otherwise no other hesitation.

The car has the code P0236 Turbo Waste Gate Solenoid

The car at first through the code P0140, but I think that might have been due to the mechanic not putting a clip on correctly. Once cleared, it never came back, however, the P0236 certainly happened right after the disconnected some stuff in order to take a look at my AC compressor, however, I'm fairly certain it is all connected correctly.

Anyway, where is the solenoid?
