JERKING!!!!! very annoying.
I own aN E320/2003,have had the same problem,the dealer changed the electronic module with no improvement,they are now changing the TORQUE CONVERTER,hopefully this will fix the problem.
On the receipt it shows that they updated the control software. The transmission hasn't shuddered since...I'm knocking on wood.

I had jerking transmission , noisy wipers, sizzling stereo, stuck sun roof, dead side mirror, over-sensitive parktronic, failed gas pump (Twice in 1 year) and even brake failure( the fatalest one) , what a nice car!!!
BTW, I am from Taiwan too but now living in HK.

I'll print out this thread and take it to my dealer the next time I go in.
i have just started getting a similar problem on my 03 CDI diesel. about 70km/h around 1200-1500 rpm and like you said more noticable cold engine conditions..
You'd notice it. Mine is like a yo-yo or pogo stick.
It really feels similar to someone who can't drive a manual transmission and gets that "bucking" action.The other tranny issue my car has is a weird hesistation if you floor it and have to back off the accelerator - it's as if the car has fuel starvation or something. Nothing happens at all.
Grrrr...

The hestitating to accelerate problem appears to have been fixed after replacing all fuel injectors, flushing the entire fuel system, and replacing the crankshaft sensor. When the problem was occuring I experienced two separate episodes of being at a stoplight, trying to accelerate and the car completely dying on me.
Unfortunately the "jerking" problem is still unresolved. Last fall I had the ETC control module replaced, but it did not completely fix the problem. The new module has changed the severity of the jerking - as if it has been somewhat dampened - but it is still definitely there and only on an intermittant basis. I will be taking my car in tomorrow for a schedule D service and will ask MB what else they can do to fix the problem.
I intentionally waited until right before the 2004 model year introduction before buying my vehicle - naively thinking that the first year production bugs would be worked out - obviously that did not happen.
Shame on MB for such a subpar engineering effort.




I went to lunch with a friend of mine and it was her first time seeing my E320. She said her dad had leased one and that it kept having this one problem where when the car was coming to a halt, it would jerk a little. Told her I had the same problem.
Btw, mine also does it when driving very slow in places like parking lots. It jerks back and forth.
Maybe we should all sign something that if we can get enough signatures and send it those geniuses at MBUSA, they'll have to come out with a recall campaign for it, just throwing that idea out there.
My advice: go to another dealer and insist (you guys are lucky in US. In Hong Kong we have no choice: there is only one exclusive distributor of MB).
Good luck!

when i brought the car into the dealer, they told me that they will replace the transmission module or something like that. after they replaced it, the car seems to be fine. the jerking only occur whenever i turn on the car for the first time during a day and started driving right away.
after 1month, the jerking is back. and what do you think i should do ? tell the dealership to change another transmission module?
