Hello every one! I’m glad to share BMW i3 repair techniques

[Stevick]

I also just checked my L2 EVSE with a voltmeter to determine if the charging handle was leaking voltage when not plugged into the charging port and read 0.0 volts. My check was not performed immediately after using it for a charge, since I had just fully charged with the L1 EVSE successfully without the 22287E "AC charging: Network voltage exists in spite of charging unreadiness" code being set. I'm not sure what to try next to determine if the L2 EVSE is the culprit for that fault, but now I at least know its not a safety hazard (though it may still potentially a hazard to the on-board charger).

Do you know if both on-board chargers are AC?

Yes

Is one for 120v (L1) with the other kicking in for the other 120v leg on a 240v L2 charge? or is one for DC and/or REX generator output?

In U.S. i3's (AC charging is only single-phase), both on-board chargers are AC chargers with a maximum charging power of 3.7 kW each. In early i3's, one charger was in the KLE and the other, in the EME. In later i3's, the charger in the EME was moved to the KLE.

I believe that an EV on-board charger always accept AC input and produces DC output to charge the battery pack. There must be some electronic circuitry involved with DC charging, but I don't believe that this circuitry is described as a charger.

I've never owned a REx and am not very familiar with how they operate.

Knocks from front suspension?
Could be piping running from front reservoirs down bulkhead and into channels running length of car. Stuff channels with insulation.

Greetings from reading your update I think you have found your problem which is your home charger,which is good .
Unfortunately an unforeseen issue has forced me to suspend my investigation for a few days but will not forget the quest . The information I posted was from the dongle I think you are reading the information from a fault code reader???
I will get the general information and post it up within a few days.
The road noise has been a feature of the vehicle from new I contacted a well thought of dealer in London who agreed with me with regards the level of road noise,, but I have nothing to compare it with on a smooth road fantastic but on average roads awful.
