I am not a master tech but.....
I had the same limp mode problem due to a faulty speed sensor in my transmission.. I myself, opened my own transmission and changed the valve body that tells the transmission when to shift. My 430 was still in limp mode and actually shifted alot worse...
"HENCE" this is because once a faulty component is changed the computer is reading the "New settings of that component still as faulty.....
I took my car to a shop that tried to clear my cars codes with an odb but you cant clear "HARD" codes in this manor.
I took it to an independent Mercedes specialist and they hooked my car up to a machine and IBM notebook. They ran a diagnostic with the car and it failed every test!!!!!
They cleared every code in the ecu and tcu, and.................................
MY CAR SHIFTS LIKE A BUTTERFLY AND EXPLODES OFF THE LINE LIKE I NEVER SAW BEFORE...
Limp mode is a hard code that makes sure you get the "BUGGY" to the benz doctor before you kill her.
Have someone that "recognizes your knowlegde about your vehicle" clear the codes for you.... then see what comes back!!!!!!!
i hope this helps you out.... Please do let me know.......:thumbsup:
