Did any of the issues get resolved?
Im having the same limpmode issue on my '08 W221 it has the check engine code P2725 for pressure control Sol E.

I have a 2006 C230 got the same code P2725 Pressure control Sol E, I changed that and fluid and filter. Cleared the code. Ran great for couple days. Then in the morning back into Limp mode again.Now it says code 2725 but this time it says Internal Electrical Component Y3/8y6(B2 Brake Control Solenoid valve(VGS)) Has Failed. Code 1749 Fault present in control module transmission. So goodluck. Make sure you do everything the first time, because it will cost more everytime you put it back together and have to take it back apart a 2nd or 3rd time. A waste of money and alot of time.

I didn't know much about these transmissions when i first posted here but now i save data from original conductor plate, virginize donor plate, write data VIN and coding to donor, install and perform adaptations. PROBLEM SOLVED. THE PROBLEM IS THE CONDUCTOR PLATE. Now i look for Mercedes with. 722.9 electrical codes in conductor plate. I have replaced several of them since and solved each of them with plate swap except one which was CAN block under passenger front seat was corroded from water damage. CHANGE YOUR CONDUCTOR PLATE LADIES AND GENTLEMEN...SAVE SEARCH TIME AND $$$.

Question though.... How did you virginize the conductor plate?

I have Xentry with special functions . vediamo and several different programs came with the computer. There are also several aftermarket tools vvdi, arbrites, cdgi, mb magic eraser and more. I can virginize and rewrite data and coding if needed. When i secure a safe mailing address to ensure safe transfer of these delicate parts i will be able to help.

I have a few of those tools myself. Didn't think you could do it with Xentry though.

Well I'm not sure about the process or if it's even possible with (Xentry) or DAS but there it's a selection under SPECIAL FUNCTIONS that says something about vgs2 swap. I don't know how to use 80% of the additional software that came with it. I'm sure it can be done with Vediamo and those after market tools though. Can also find donor plate with same numbers and send them both to someone who clones or copy original info to donor. Once installed you might have to relearn range selector or something but might be plug and play.
