Featured Replies

Hi all,

im having trouble with my boot switch. I’ve replaced with a new one but still does not work. I’ve check that all unlocks with one push of the key.

can only open with key boot to open boot. Can anyone help. Thanks.

Hi, welcome.

 

Sorry I'm lost with what you've put.

Do you mean that when you press the (bottom) unlock button on the remote the doors all unlock but not the boot?

Do you mean you have to press the middle button (with car/boot symbol) on the remote to open the boot?

 

 

Have you had the car from new so know if any settings have been altered with a scan tool?

 

What tests did you do to lead you to change the switch?

That is correct. I’ve had the car from new. Thanks .

Thought switch above plate was the problem so bought a new one. As the key unlocked the boot thinking it was the right move to start with.

So, if I've understood, the problem is with unlocking rather than opening the boot.  Could be mechanical, electrical or computer so usual tools plus multimeter and diagnostic scan tool - what have you looked at and done other than replacing the switch?

 

What locking setting do you have through the Infotainment menu?

 

Hatch or estate?

 

Trim level (S, SE, SE-L(?), other)?

I’ve no other tools other than a diagnostic tool but I need to find it first. The settings are for all doors. It’s a hatchback and trim is a s. 
I’ve never had any problems with the lock it happen instantly

If you fitted the new switch you have some tools at least, plus your senses, eyes, ears, nose, if the diagnostic tool is a good scanner that'd be better than just an error code reader but with either it'd be worth plugging them in to see what can be found.

 

Only last week my neighbour couldn't open the boot of the car and that was just a bag handle trapped between the latch catch, soon sorted with a visual investigation and (feeble) muscle power.

I've just had a thought (a rare event) when you press the remote's middle button (with car/boot symbol) this unlocks the boot but if you press and hold that button it unlocks and opens the hatch door, depending on which of the two you are doing this could help perhaps with your diagnosis by trying the other (if you've not already done so).
