    This was the fastest SUV in the world when it was released; the BMW X6m twin turbo powered by the same engine as the F10 M5. I found this at an auction as a Lemon Law Buyback from BMW and then Repossessed by its last owner. It was dirt cheap, but for a good reason. Like all other cheap auction cars, this might just be a big mistake...

Turned out he took it to Best Buy to have some huge sub box installed in the trunk, and they took power from somewhere that they managed it to get into the rear canbus.

    Hello Sam, too bad you live on the other side of the continent as an electrical engineer could identify the source of your problem. I have some comments based on my observations. Since the center display goes on and stays on when the relay is removed, but appears to be resetting due to apparent power drop when the relay is installed, I would be looking for a module that is pulling too much current when it is activated. Now on the canbus system. Canbus is a multidrop system meaning that all the modules share the same pair of wires for communication and they each have a unique communication address. Mario is correct in that the canbus signal could have a problem. Canbus is a differential pair twisted wire which means both the wires have the same impedance to ground or +12v as this gives the signal better common mode noise immunity. The canbus also has a 124 ohm termination resistor at each physical end of the bus (one is at the master device). You can verify the presence of these resistors on any location in the canbus network across CAN_L and CAN_H - make sure power is off or disconnect the battery. The measured resistance should be about 62 ohms. If the termination is present, the next thing I would do is put an oscilloscope on the operating canbus to make sure the canbus signals are the correct amplitude (about 4V peak to peak). If the canbus checks out, then you can start pulling fuses to find out which module is loading down the +12V distribution bus. If you need more advice, just reach out to me.

    • @a20axf
      @a20axf 2 ปีที่แล้ว +10

      This reminds me of a video I've seen recently regarding canbus... It turned out to be a faulty reverse camera was the issue and was indeed detected by using an oscilloscope. I can't remember the correct terminology but, there is a large main fuse that can often cause similar issues if it's fully broken or potentially cracked enough to make contact sometimes.

    • @russellhltn1396
      @russellhltn1396 2 ปีที่แล้ว +7

      I was thinking CANBUS as well. All it takes is a pinched wire, or a break before the termination and the signals will start bouncing off that "disjoint" and cause all kinds of problems. Normal "chatter" is interpreted as something else causing the car to behave in strange ways. Yet, the problem may not be visible with a regular meter. (But it's a good start.)

    • @zxggwrt

    Hey Sam, I had the same issue as this on my 2008 BMW E70 X5 (same platform). Water was pooling behind the engine partition/cowling near the brake booster and on the other side near the blower motor. It seems to be a common issue with these. You need to make sure those drains are clean (they fill with dirt and leaves) replace the partitions (such a poor design for waterproofing). Anyway, there is a ground cable inside one of those compartments and if it has been sitting outside and filling with water, the cable will corrode. On the other side there is the engine fuse box (another great design). Mine was doing the same headunit flash and no cluster. Hope this helps!

    Sam that rear junction where you pulled that relay from needs to be taken out, opened up and inspected. That relay shows signs of water getting to it and if water got to it then it got in that box and I suspect it is moving around inside of there shorting out various things. I bet you if you open up that rear box and inspect the internals you will find corrosion.

    I had a similar problem when I was an Audi tech. I used an oscilloscope to view CAN bus communications. It should be a clean square waveform mirrored across the X axis, CAN-HI and CAN-LOW. What I saw looked more like an analog signal with no symmetry or pattern. I just started disconnecting and reconnecting all the modules until the waveform cleared up. It turned out to be the convince control module which was located under the driver's seat in that model. No visible sign of damage but I found out later the car was flooded at one point.

  • @knavekid

    Driving with the relay removed shouldn't hurt anything. The systems affected are powered through the relay and are simply not active with it removed. My guess is that one of those systems is causing the problem when powered. I would pull all the fuses downstream of the relay and plug it back in. It probably won't chatter. Then, plug the fuses in one at a time to isolate the problem.

      I agree. Something which that relay is powering is causing the issues. Pulling the relay robs that thing of power and the problems go away. In fact I bet if you pull all of the fuses that power things after that relay then the relay will stop chattering. Probably the central module sends a CAN signal to switch the relay on, this powers the bad module which trashes the CANbus, so the relay goes off. Now the CANbus is ok so the relay comes on again. The situation will just oscillate between the two states and you have a chattering relay.

    I've had a German car develop a similar problem and we traced it down to the CAN wired being fed 12v from the battery. The fine folks at the dealer had sliced through the main harness wires to install a lowjack device and allowed corrosion to set in and eventually bridge a 12v wire to the canbus wires. It would be interesting to see what voltage you have on the CAN wires...

      Yes, this sounds like an issue with the CAN bus itself. (stuff not turning on/off because it hasn't been told to, K-CAN Errors because the modules cannot be reached...). It could be a broken module as well, which can affect the bus, but that failure mode is very unlikely.
      Checking the voltages on CAN-H and CAN-L is a good start, maybe a more sophisticated instrument, like a scope, will give you a better insight on what the bus is doing exactly.

    The CanBus is a network with a plurality of subordinate microcomputers below. All the modules in the car talk to a master module and share segments of that network. One bad module can clobber the messaging of all the other good modules randomly. There are CanBus analyzers that will report when messages get corrupted and even say who was involved. Ideally the modules will identify their failure and just nicely code out but if something is really wrong (broken pin etc) then it can do this. IE: It can clobber a message if it does not detect the message is in progress.
    If the module you replaced is oscillating the cutoff relay then some stimulus to it specifically is making is do so. So I'd focus on errors coming specifically out of it. Of course if its the master the errors may be a subordinate. Okay - so what is coming from the subordinates that is of a magnitude that a cutoff would be necessitated? Since the relay is chattering ( which would heat it up ) then is it possible to pull easy to access subordinate modules and just see if the chattering stops? I'm surprised the shop manual does not have a flow chart.

I would do this even though it's reading fine, just so I didn't run around pulling everything out of the car to fix a slightly bad relay, even though it is likely fine.

  • @thetechgenie7374

    I have that car it likely going to be the central CAN bus module, or other module on bus, or corrosion in harness, as had similar issue. Thankfully got it cheap for very reason and did trace it down and fixed it. You have the right idea process of elimination pretty much? Find what circuits those relay are on and trace it out. Look at schematics it help you break down the individual systems and you can trace easier and find the fault or bad module quicker. That relay being melted something likely drawing excessive current, or from kicking on and off so may times as for cutoff?
    Yep costly and unreliable but smooth when it works. Had to put 4K in parts as had other issues as well and many days of labor to get it right. Pretty sure something else will break like any BMW I owned over the years? I would inspect that rear junction as well for signs of corrosion?

There is a guy that lives not far from me and he has 4 BMW SUV's. He has a metallic green X6M that was designed to look like the Green Goblin from the Tobey McGuire Spider-Man. Another X6GT that is done in stealth black ceramic and chrome black highlights with oversized wheels and rear spoilers. The inside is black leather with yellow piping. It looks like a Batman vehicle. He has an X2 in pearl white and chrome metallic blue that resembles R2D2 and an X5 that is painted by hand in varying shades of tan, green, black, brown and cream. Has giant tires, winch, roof rack with spare gas cans, water cans, sand ramps, shovels, axes, tent and stove. Inside is a custom gun rack, 4 full plate carriers and ammo cans plus magazines. He's totally nuts and you can see him in his driveway yelling at his cars. Cursing at them for not working. Then he gets in his Ferrari 488 Speciale and leaves. I tell him all the time to start a TH-cam channel or TikTok. But he won't.

    The relay clicking on/off rapudly in a DC system sounds like a loose connection maybe shaking with the engine. Rev the rmps and see if it flickers faster. An oscilloscope is great for this.

    You can purchase a DC clamp on amp meter. We had automation systems that had dozens of sensors on one fused circuit so finding a short was a problem. Checking the current to a single group at a time would quickly narrow down where the fault current was going. I really think you will eventually find a damaged harness or corroded ground connection.
