I went out for a drive earlier today and my active bonnet warning light came on and began flashing for the whole of my journey, I have not been in any incidents of any sort and the actual system didn’t activate, only the light… all I can think of is that I shut the bonnet too hard when topping up my windscreen washer fluid. I plan on calling Mazda tomorrow but in the meantime does anyone know if this is prohibitive to me driving it since it is my only way of getting to school. Any help would be much appreciated, my only real concern is that driving it will cause the sensors to activate and blow the bonnet off the car as it would in the event of a crash.

thanks… I already checked that post and seems as though that’s only when starting the car and then it goes off again, mine is persistent

According to the manual as well as the flashing light you should also get a warning beep for 5 seconds every minute. You will be fine driving it until you get to the dealers.
Aren’t you too young to be driving if still at school

Great first car and hope you resolve the warning messages, will be interesting to know the outcome.

cheers, it was just a sensor issue causing the light to come on, think the bonnet overreacted to me shutting for some reason, thankfully nothing serious

Hello every one
Just had the same issue today,
Flashing light, active bonnet

Check that the electrical connections behind the bumper are ok first it may be a very easy fix.
You could try the old ‘IT’ trick and turn it off, wait 30 seconds and turn it back on.
Ignition off and with all doors and boot shut then disconnect the negative battery terminal to turn it off and reconnect to turn it back on.
Thank you for this , do you mean the Positive ?
It does not realy matter, but it is ‘best practice’ to remove the negative (earth) first when ‘playing’ with batteries. It helps to avoid any unintentional ‘welding’ moments!!!
This happened to me over the weekend. Turn ignition on, do not start. Press brake and accelorator same time and hold for 10 seconds. Start car, turn steering wheel completely left the right twice. Cleared for me.
Went to start my ND1 a couple of days ago and it wouldn’t switch on/go to ignition ACC. I removed the battery and charged it. The car is starting ok now but the active bonnet system light is flashing a pattern = 4x then 1x and repeat. I’ve driven it 10 miles and it’s still flashing and I’ve disconnected the battery again and still flashing.
I plugged it in to my laptop via a wee ELM427 cable and software I downloaded earlier. I cleared the DTC/codes, but the bonnets system error keeps reappearing.
Car hasn’t been hit or anything, it’s been parked up on a trickle charger in a Carcoon for 2 months.
Could it be a failure in two components or could it still be a bad battery. Seems unlikely to me that two parts of a system could fail like this, more likely one is faulty or maybe a plug is wet causing a short circuit.
Any advice appreciated guys.
Must be the only one with this problem 
The Bonnet warning system light has now gone off 
However the infotainment screen is blank and won’t reset, or play music etc. plus boot still opens occasionally when clutch is pressed (not every time).

It does sound like water somewhere in the electrics, often a frustrating task tracking a solution down.

Looking at similar posts in your shoe I might have a look at the ESU located top left passenger footwell for signs of water damage :- ND boot (trunk) opens while driving and button stopped working . Good luck tracing and repairing the fault.

Going to add another update.
I plugged my car in last night and got a code:
U3004
This corresponds to a start stop unit that my car doesn’t come with. Googling the unit brought up this diagram/
I noticed that it goes through the heated mirror fuse. I opened the fuse cover inside the car and noticed that the dash cam was piggybacking off this particular circuit (proper Nextbase wiring kit). I removed the adapter and just connected the fuse directly.
Now my audio system is working again
However I still have an issue with the clutch pedal triggering the boot switch. When I press the clutch before I start the car, the boot latch opens. If I start the car and get out and close the boot, I can operate the clutch without triggering the boot switch to activate as long as the car is running. Then when I park up the boot switch activates again when the clutch is depressed.
There is a switch in the clutch that prevents the car starting unless it’s pressed isn’t there?
The only thing I can think of is that I installed a Mazda 6 boot switch (in the blank space below steering wheel on right hand side) a good while ago (wiring harness was already in car) and perhaps this is connected to the clutch issue ? However the switch has been installed and working for 1+ years
