Hi to everyone,

I just purchased a 2003 s600tt with 94k miles on it from a dealer.
I test drove the car and fell in love with it. I took the car for about a good 20 min, let it rip a little just to fell the power, everything was fine no codes and so I purchased it.
On my way home all the sudden the car started to shake and the ESP malfunction came on. Took it to a local shop to connect to a computer and they told me it was the throttle body actuator.
I spoke with a service rep from Mercedes, he recommended that I should open the throttle body and try to clean with brake fluid.apparently they r known for this throttle body issue. Just was wondering if anyone had an issue like this and how did it get resolved?
Thanks

Clean it with brake cleaner, not brake fluid

Demon954

Correct Tusabes, brake cleaner not fluid. So I tried to clean and still same thing. Shaking at low rpms, ESP light and safe mode.
I have no more patients with this and decided to buy a used one since a newnone cost $1600. Will upstate when it comes

Is there any relation between ESP and throttle body actuator?

Demon954

Don't know myself, but what my local shop told me is that the car has a throttle body actuator problem and the computer is making the car go to ESP safe mode from improper throttle reading. How true is this I have no idea

Hi everyone again
Update on the issue

Just changed the throttle body actuator with same part # started the car, still same issues.

Went to my local shop to clear the codes, no luck there

Car symptoms= when starting car is shaking, press on the gas seems to be fine and 7 sec later the ESP light goes on with pre-safe inactive
Read the codes it was c1041-002 can message 47-5
Also showing me the exact throttle body actuator code also
I've changed the actuator so I know nothing is wrong with it

I've checked all the fuses, everything seems fine next step thinking about replacing the ESP module

Need help!!?

Thanks again

Was it checked on "a computer" or SDS?

Why can't you take back to dealer?

It was checked on star computer.
Bought the car as is
