c350 - slugish after tcu reset
I bought a used 2008 c350.
After reading a few posts about the car on this forum, I decided to try the following tcu reset procedure.
Steps to Reset the TCU. Resetting the TCU will reset transmission to factory shift points and the car will 'relearn' your driving style.
(1.) Turn the ignition key to the on (not start) position.
(2.) Press the gas pedal to the floor and hold for five seconds.
(3.) Turn the key to the "off" position (don't remove the key), then release the gas pedal.
(4.) Wait at least two minutes for TCU to reset.
After doing this my transmission became extremely sluggish. Before when I was in sport mode, the car would jerk (violently) from a dead stop when I slammed on the gas pedal. Now it seems to take its sweet time.
I'm wondering if this is normal, and if it will fix itself with time.
Thanks
Richard

Try waiting for a few more days. Could probably just be the learning process. Anyway if it still doesn't work I'll probably try doing the reset again or taking it to the dealer.

Why are you resetting the TCU yourself? Even if it is a 2008, it should still be under warranty. I had mine reflashed because my SA told me that my software wasn't exactly a perfect match with the ECU. I'll take his word for it because it complete fixed my sluggish, reverse lag issue.
