OK - 13K Miles 2011 and I have one big issue plus a one off event...

1. At low speed, shifts from 1-2 or 2-3 are rough - Happens when the van is warm and jerk is pretty significant.

2. Bad start where engine started and appeared to be running on less than 6 cylinders - very rough but happened once. Shutdown and restarted and all ok.

Vehicle is at the shop and absolutely no fault codes for either the transmission or engine thus they cannot find any issue. I plan to take a drive with a mechanic at lunch today but what else can I do other than set up a camera? Is there a process to hook up diagnostics to the van while I drive around??

MB need to have better diagnostics because they put the onus on me to prove.

...and its the EGR Valve!! After saying they could not reproduce the issue, I was able to demonstrate on a test drive. Sad about no codes - Puts the onus on us as if we make this stuff up.

Also - Whats with 10 years of EGR valve issues?
