  1. I’m playing Tidal via a Bluetooth link. Works perfect. No need for any cables, mods etc. That is in 450h though.
  2. Not sure about this safety aspect. AGM is still not gel. It is going to leak just as the wet battery would in an event of a crash.
  3. I can confirm that my YBX5005 is doing a fine job. More than adequate to what is required of an auxiliary battery. The 65 Ah vs 51Ah (original) also helps.
  4. It only takes a call to Yuasa and they will send you the elbow adapter. I also noticed they have those in Halfords. They might be attached to actual batteries though ;).
  5. Vadim, If the tailgate motor/ECU unit is no good to you anymore and you are willing to ship it to Ireland, I can look at it myself and ask our technician to investigate. I work for an electronic RF manufacturing company - we don't deal with microchips as such but would know were to look for fault. If we are capable of fixing it, we will and I'll ship it back to you. Let me know if that is of interest.
  6. That is what i put my bet on. On the pictures you show, there does not seem to be a cover over the electronic board. That is odd. I would have thought that it should be encapsulated in a plastic cover with a gasket, or did you actually removed it?
  7. Steve, while I agree there seems to be a correlation between battery failures and issues with the tailgates, the latter might not necessarily be caused by the former. There could be another unknown factor that causes both i.e. an intermittent short on the ECU board draining the battery and ultimately causing the ECU failure. There also seems to be the possibility that moisture and aging effects take place and over time, especially when the boot and therefore tailgate is not in use, bad contact sets in. It has been raining almost every day for the past 2 weeks here and I did not use the ca
  8. Thanks steveledzep. It is lashing today so I cannot look into it right now. The tailgate motor itself is very pricey so solving this problem would save us all here thousands. My experience with it is that sometimes the tailgate ECU does not power on - gate does not lift or close and the boot lights are out too. This can be due to dry solder joints in a specific spot on the PCB or a failure of some relay. Wiring or connectors are most likely not at fault here but that is just a hypothesis. I’m hoping to look into this more when the weather improves.
  9. That is a strong possibility for sure. The power lift mechanism is right under the roof rail mounting. It’s ECU is however encapsulated and therefore unlikely to let the water in. Nevertheless this cannot be coincidence as there are too many vehicles of different age affected. last night I went out to the car to check it once. Unlocked the car and the tailgate would not open. Locked it and unlocked it again, it opened and closed fine 3 times.
  10. I had an issue with a battery 2 months ago. Replaced it, charged anew one in the car, and the fault only developed now. Highly unlikely that a battery is an issue here. If charging or low battery has caused this issue it would first of all be permanent not intermittent, and second of all it would surface right after.
  11. It seems to me that the issue is rather systematic and therefore can be fixed. The Techstream code results would certainly help in confirming that. I don’t have it so a multimeter will have to do. My initial angle on this is that it could something to do with a dry joint at the ECU board. Either the ground is floating (unlikely as the board should be grounded in multiple points) or lack of/intermittent power supply. My bet is on the latter. If this is somewhere at the input to the board it should be easy to fix, if it is at one of the ICs, it is a completely different game. Either way the t
  12. Hi @steveledzep , Same thing is happening to my car, intermittently at the moment. Did you fix the issue and if so how? Thanks.
  13. Thanks Herbie. Seems like a common issue with the RX. I would have thought that someone has found a solution to this already.
  14. Went to the car and unlocked it. The rear gate went up with a press of a button as it should, then 5 seconds later the lights in the boot went off and the gate would not close (other than manually). Went for a 10 minute drive, stoped and opened and closed the gate twice with the dash button. Came back open the gate once again and the lights in the boot went off and gate wouldn’t close. Intermittent for sure, but where to look for a fault? Looks like a dodgy ground to me.
  15. @Herbie, Same thing here boot does not open and no lights in there either, no two beeps etc. All was fine yesterday. Car started fine today too. Could you please send the info on how to diagnose the fault? Thank you.
