I folks are suppose to be "zombies" but in MY opinion, you are working on one of the hardest vehicles. That transmission alone, proves my point. Glad to see you maintain the transmission, but I was "cringing" because of all the parts. But you guys did an excellent job. 👍
Although I've never used one there are bluetooth-based OBD readers that basically turn your phone, tablet or laptop into an OBD scan tool. In theory this could give you way more features and capabilities than a proprietary scan tool, with regular updates and bug fixes and the ability to connect online to OBD databases that could give you a lot more and more current information about your vehicle and any codes that come up, keep up with new vehicle models, computers and parts as they come out, and store an unlimited amount of historical data. Only one of our cars uses OBD II and I'll probably sell it soon, so I've no need for such a tool, but you might want to look into it.
I'm just an amateur, but I'd start with a good cleaning of the battery posts/clamps back in the trunk there. Maybe check the battery's health with an impedance tester. I do know that on some modern BMW's with rear-mounted batteries, an aging battery can make all sorts of weird fault codes crop up. If it comes down to hunting for a short in a wiring harness, good luck! This could be a fun/frustrating series.
You are more than an amateur, and you should watch the next video that we hope to get out by Friday that shows the actual problem. Hint, it has to do with the many sporadic fault codes on the transmission...just like you suggested, but it wasn't the battery. Paul & Diane
Check the cabling it's probably corrosion somewhere.. multi system failure means the module is bad or something is bad with cable but it see's the trans module and was able to talk to it so probably not the wire to ECU to trans cable but something after..... FYI you should of looked at freeze frame data and see what the car was doing at the time when it send the code.. to know what is really wrong you might have to back problem it with a external scope.. so see what the data the sensors are actually seeing
Thanks, another great analysis. We hope to release the video with the answer on Friday and you will see how right you are then...or you will tell us what we misinterpreted 😎. Paul
@@carzombies if corrosion ... they sell electrical contact cleaner its a spray.. and I would use that a couple of times... spray it let is sit for 20 sec's so it breaks it down,, and wipe it off and spray it again.. and you can use air to blow away dirt and contact cleaner... put the connector together a few times in and out and re-clean it... then when your done use some die-electric and put it on female side of plug... and push it in/out a few times... and you should be good... there is tools to remove the pins out if you really need to get a deep cleaning... but that's more in-depth I wouldn't bother unless its necessary.. they are normally held in with a flower shape clip that expands when installed.. similar to an electrical outlet back port that you can just force a wire in... now corrosion can go up the wire underneath the insulation.. not really common but something to look at..

The transmission is the hardest? I didn't know that...Thanks for the support and kind words.

I've been in limp mode lately, too! That's why I ice my knees at night.😃
I've been icing my neck every night. Paul can really be a pain...😜
Diane
Both of u are amazing
Thanks. We really appreciate the support. 😊

FYI CAN is a communication standard is basically OBDII fast communication
Thanks! That solves that question.

@@robrocco5420 This looks like exactly what we need to do. Thanks for the tips on how to do it.
