2014 C4 Grand Picasso Exclusive Boot not opening.

[Paul-R]

What makes you so sure the existing battery is fine? Has it been recently replaced for instance? If yes, was it the correct battery?

Update if it helps anyone. My problem turned out to be the tailgate control module itself.

Finally fixed my original issue where one of the boot struts was stuck open and would not close.

I replaced this strut with a second hand one and the boot now opens/closes with the boot button.

However if i use the key fob it opens but will not close correctly and i have to manually close it with a bit of force. Do you have to close it with the Fob as well or can you use the boot button?

I wonder if a BSI reset would help here (if you have not already tried the boot reset procedure)?

Thanks whats the boot reset procedure have not tried it?

I am NOT certain there is a boot reset procedure for your vehicle, but I have seen threads on this forum where such a procedure has been mentioned. If such a procedure exists for your vehicle it should not take long for a Staff Member to post it here. Failing that, a BSi reset could help.

Hi
2014 GP
I replaced the faulty electric strut and boot was opening with no issues.
However recently the boot is only opening up about 1/3 of the way before 3 short beeps and it stops opening and wont close using the button. I have to manually lift or close the boot.
Also as per attached pictures the left hand side of the boot(passenger side with second hand strut) is not closing correctly(side with replaced electric strut) and i can put my finger in without any problems. On the other side(drivers side with original strut) the boot is tight against the chassis. #

Where are the sensors for the boot so i can check if they are blocked and not opening the boot up fully?
The second hand strut i bought and installed. Do i need to reconfigure or reset this so that its closing correctly?

There are 2 forms of obstacle detection:- direct and indirect.

On 7 seater versions, there is a seal that contains the anti pinch sensor strip - this is an upside down U shape and contained in the seal that extends from approx. where the parcel shelf is upwards. This is the direct detection on 7 seaters in addition to the indirect motors described below:

The indirect obstacle detection is determined by the motorised tailgate ECU which senses a peak in the current and stops the action. If this happens manual initialisation is required:

Initialisation of the motorised tailgate:

• Manual opening of the motorised tailgate (If necessary)
• Manual closing of the motorised tailgate

The struts are also balancing struts, so if they are not quite right there may be issues especially if one is more 'worn' than the other which may happen with a second hand one.

Have you been able to resolve the issue, I have the very same thing on my C4 GPII 2017, the boot is skewed when closed by hand.

I did diagnostics I have the following errors:
(Seems attaching images doesn't work for me, or I am doing something wrong)

Do I understand correctly that the errors boil down to left strut is due for replacement, or this is just misalignment, i.e. requires recalibration?
I also don't think it's the pinch sensor because I dug around some menus in DiagBox and got this:
(see first attachment)

There it seems antipinch is not triggered.
I do have a weak battery, but it was working fine on engine running... until it didn't now I open the boot and hear those three beeps of doom...

If this can be recalibrated do just go for repair and so on, and will be lead by hand in that process or do I need to actually go to a workshop with that?
I'm perfectly fine with doing stuff like that, but I don't want to mess things more than they already are...

I forgot to mention that I can open it manually but when gong down it a battle I need to go gentle with it: push it down a bit then up a bit and then more down until it's down...

Can I ask if you ever got to the bottom of this and what the issue was in the end?

Do you have the same issue? I.e. missaligned boot?
