Hey everyone,
So I have a 04 e55. When I go WOT my car will not upshift in any gear, even when I click the paddles on steering wheel or shifter, in video I click it around 5 times as you can see and won't shift untill rpms drop(I never let off the throttle in the video). When I'm not a wot it drives perfectly fine has no shifting issues, anyone have any ideas?

(I've changed the plug that goes bad and the conductor plate)

Anyone? Any input?

Denroll

Does it do the same thing in M mode? What's with the ESP warning?

Daarthvader

Does it in every mode, and esp came on because the delay in shift does it every time when it hangs in gear too long

ESP is throwing a code. Scan and see if there are any codes...active or pending. The car knows what's wrong.

Daarthvader

I did with STAR only code was for the esp due to gears not changing
This is the code

Is a speed sensor code being thrown?

Daarthvader

See previous post I just added in the code. This code only pops up on WOT. Never driving with 1/2 or even 3/4 throttle

Hulk

Check your bypass valve wires, hopfully it's that

I will check that out when I get home!

Dang, all wires are good with correct voltage

Do you have a Pedal Box or Sprint Booster that may be sending bad throttle position signals? Maybe the electronics in the gas pedal itself are bad?
