Toy are a true legend!

Have you checked out the electric A/C compressor or have you noticed any issues with the A/C? Those pumps are pretty notorious for breaking down internally, causing aluminum to get pushed through with the refrigerant and the high voltage shorting/bleeding into the low voltage 12v system. The insulation, also called the isolation, is a system that monitors and ensures the isolation between the 12v low voltage system and the high voltage system. If it detects high voltage on the 12v system, it will throw an isolation fault. There is a braided mesh wire (12v) within the insulation of the high voltage wires that is monitored throughout the system and common chassis ground. If a wire gets pinched, wire insulation breaks down, or a component (such as the electric A/C compressor) shorts internally, the system will measure higher voltage on the 12v system and throw said fault. You can usually narrow it down by disconnecting or isolating components and HV wires, then monitoring the isolation test values to see if the high voltage is still present on the 12v system. That requires the BMW diagnostic software though... just be careful and don’t work on a live hv system.

great job

How do you change the kls and do you have the program the whole entire car?

How did you test the cables before investigating pal? Did you do anything when refitting like contact cleaner or grease?

Hi Shaun, I'm having the same problem with my car and I finally found the EME module online but after watching your video, maybe it can be fixed without me having to replace it. I was just wondering, do you know what coding tool you need to have if the EME has been replaced or anything changes with it? I'm not sure which scanner tool I should be looking for and I cant move forward without it. Thank you!

Hi. I just got the same message and after talking to bmw, it seems it may be due to a software problem in external charging stations!? Any new insights on this?

I got this error and then my ac went out. I’m assuming it’s related. Do you think if I replace the ac compressor I’ll be back to normal?

Its always the heater if this problem occurs

I want to know how to change the k l e

You shouldnt touch any part of the high voltage system without wearing insolating gloves, for your own safety

How to unlock battery after accident ?

How did you fix it? My 03 18k miles says same thing but will not drive.

Hi. What is the car mileage now you have o your i3 ? Thx. In your videos there are many problems with i3 i don't understand why. My i3 2014 is only 30K kilometers and no problems.

how can you switch off the HV system to touch all those cables ?

Cant say i would want to own an I3 after all the problems you've had
