I’m looking for technical help or recommendations on: __boot release
Our boot opened several times today whilst driving with absolutely no interaction with the key fob button at the time. The rear underside button has stopped working too.
It also opened on turning off the ignition.
I’ve ordered a new bottom from mx5parts but I wondered if anyone else has had similar and what was the cure?
The fob button does open it.
Tried the spare fob and that opens the boot but the external button still doesn’t work when in close proximity etc.
I had that but also had A LOT more issues and found it was due to a fault ESU (Electrical Supply Unit - computer in the top left of the passenger footwell).
Hopefully yours isn’t related but might be worth a check of a few other aspects:
Thank you. I had a look at that esu a while back when I had window trouble that turned out to be sensors in the motor and I remember it being impossible to get to. How did you get to it? Was it a main dealer repair?
All I gotta do is find one. It’s worrying as I don’t want it to pop the boot when we’re away from the car, that may not happen but it is something I’ve thought about.
When you mentioned esu I thought it was the one that’s higher up under there, that one I can get to so it should be easy enough once sourced.
Did you have to do any clever resets afterwards.
Nope, I just replaced the unit, started the car and everything was fine, no coding needed or anything but it isn’t a cheap unit at ~£300 and that included a discount as I have a service plan.
I would check all the other aspects I mentioned in my thread when this occurs to see if it is definitely the ESU or something else.
Strangely today it seems to behave normally and everything is back to normal.
Maybe the sun being out yesterday helped warm up a damp spot and that cured it. Will provide updates if it reoccurs.
I love that this forum allows so much information exchange. It’s really helped me with several options and just having a post like this hanging around could help someone in the future.
Was this problem ever solved? Has anyone else here dealt with it? I have this exact same problem with my 2016 ND. Nine out of ten times, when I turn the engine off via the start/stop button the boot pops. Sometimes when I open a door the boot pops, sometimes when I close a door the boot pops. Sometimes when I unlock the car the boot pops.
I can leave the key on the passenger seat and sit in the car with the engine off, five minutes later…the boot randomly pops.
Its behaviour is completely different from one day to the next.
When the car is locked the boot never pops. Back at the start it would pop decelerating at a red light but that behaviour ceased and the boot has not popped since when the engine is running.
Sometimes I can just hear the boot release solenoid operating randomly. No, I am not pressing the button accidentally, and no, it is not the fob because I have tried two and also shut them in an RF blocking box and it still happens.
Currently I have to start the car and close the boot for it to not happen again.
Also, the external button at the back that releases the boot stopped working.
Has anyone got a similar experience? Did you fix it? What fixed it? This is driving me nuts.
If anyone has sorted it, I’d guess at it being water/moisture in the release button. Disconnecting it would prove the theory, probably worth pushing the boot latch with a screwdriver to test it rather than shutting the boot and risking it never opening again.
Mine stopped messing about once it had some sunshine and dried out, never happened again so I’ll be interested what the cooler weather with rain brings this season.
