So what is TSB 21-2091 about than? Any changes in the UI, functionality or is it all invisible for the user and is the noise gone?
EDIT: TSB 21-2091 is for the 12V battery drain issue. So how does this relate to the loud noise problem?
You better check if there are transport locks fitted that have not been removed as per my MME. Detected this after 1000 miles and a bouncy ride. Picture is from left front spring and damper.
The yellow thingies are the spring locks....and should not be there:mad::eek:
You can win back some time by increasing up to 14 Amps on the wallbox. WOrks fine with me without the roaring noises.
Getting a 1 phase charge cable from Ford to solve the problem made me LMAO. What kind of solution is that, seriously? I'd rather collect all the angry notes under my windshield...
I'm unaware of what type of 12V battery the MME has, but lead-acid batteries are dead when discharged below 10%=11.51V). AGM or Gell might possibly survive such a discharge when directly charged and topped of.
You must compare apples with apples, so if you take the phase shift of 120 degrees into account you also have to use the 400 Volt (the max amplitude between 2 shifted phases instead of 230V. So 3^1/2*400*16A=11kWh but in short you can take 3*230*16=11kWh. Either way around :-)
1st off all, downplaying this issue does not make it normal. Try to explain this to your complaining neighbours during the night.
This charging noise can be as loud as 76 dB which is not classified as normal. I'm suffering from the same problem and it seems that not all MME's have this issue in...
Hi, as a Dutch MME driver I experience we are not getting much support from Ford in solving issues that occur in the MME. Although we have a strong forum (at least at tweaker.net see here ) where one of the members has put a lot of effort in collecting issues with the MME see here ).
