Our mission is proceeding as planed, aftermarket support for EV’s is in “3rd gear”. New German customer sent his Tesla P85+ from Tesla Service center to Zagreb Croatia, to try save the 9 years old battery. All battery defects are received over the line, waiting time is zero because in situation where is internal isolation or cell imbalance defect more you wait repair cost is increased.
This one had rotten fuse cover which leaked water inside fuse and fuse box. Owner responded on time, delivered vehicle and we repaired it same day.
Message to all owners to share this note:
All older Model s 2013 and 2014 if they never visited Tesla Service center to service any kind of battery issue, you probably have same problem waiting to happen (Tesla almost always change fuse cover if they remove battery for servicing).. Contact your service (Tesla or 3rd party) to make visual inspection and change the fuse cover.
There is one more preventive service what should be done is called “cleaning of umbrela valve cover and umbrela valves”
Errors: BMS_w123 and BMS_f123
Vehicle : Model S P85+ 2013

Tesla battery cost: 9200€ + tax

Hi my tesla has t been able to drive in months and I have been getting the same 2 codes but don’t see any issues what all do these codes mean could you text me at (309) 368-2125
You must check inside your battery pack it is likely to be some moisture in the fuse and/or contactors housing as well as the battery itself
I have the same errors on my Tesla Model S in Guatemala, I dismounted the battery pack, fuse cover looks OK, no rust, no moisture inside the housing. I looked at the front battery housing too, there’s no evidence of moisture there around, all looks new and dry…
I changed the fuse and proceed to mounted the battery pack again, the errors doesn’t disapeared… might the BMS be reseted? What else could be checked on the pack? Could you help me please? Thanks!
