boot won't unlock

Featured Replies

Hi

Just purchased a 2005 vrs Fabia. Got home and tried to open the boot (all doors are unlocked) boot still locked! If I lock the car again and then hold the boot release on the key fob boot pops open. Is this the only way to open the boot or should the boot unlock with the doors.cheers

Can you hear the motor when you try an unlock? I have to press mine down while pressing the button (on the boot itself) for it to open it

It's a trick. If I open the left back door the boot springs to life and magically works again!!

That is a sign that the microswitch on the drivers door lock is failing/failed. You should find that the boot will function if you open any other door with a working microswitch before opening the boot.

 

A failed microswitch on the drivers door does not tell the car that the drivers door has been opened, and therefore the boot finger switch remains inoperable unless you first open one of the other doors with a functioning microswitch. It is a very common issue across a lot of VAG cars of this vintage.

 

Signs of a failed drivers door microswitch are:

 

Interior light does not operate when opening drivers door.

Lights-on warning bleep does not work when lights are on and drivers door is opened.

Car re-locks itself after 20-30 seconds of unlocking even with drivers door open (unless another door is first opened or key inserted into the ignition before 20-30 seconds have elapsed).

 

Check for the above symptoms (these symptoms can occur randomly if the microswitch is failing intermittently).

That's  "Good-to-know" info for me, as I've been getting intermitment and inexplicable fault on the courtesy light and it isn't obviously being picked-up, along with a bucket load of other stuff, on the  main dealer "Health-Checks" which are currently in-vogue with the marketeers. Oh for the days of a competent spanner jockey that was allowed to just get on with it and do his own thing !

 

So, the conclusion we can draw from this is that VAG Fault Reporting System isn't designed to directly report on individual low level components but stops short at the system level e.g. door closure throughout the car. Presumably, that's why the driver's door fault is only detected as consequential fault caused in another component.

 

Is that good engineering practice, given that it would be reasonably easy to give all components  an "Intelligent"  digital address (Especially if they cost £20 + and even if there are thousands of them, which there are not.)  -doing so might even save them wiring in the "Link" part of the circuit with the other components.

 

Hardly, Vorsprung  durch technic.

Yes VAG cryptic secrets, same for the failed brake light switch, or even on some VAG cars, failed brake light bulbs. I used to worry a bit when my old Passat V6 4Motion made "putting" sounds from the front wheel arch - I worked out that was probably it flushing the EVAP canister.

Mine was simple. A fuse!!!!!!!! If your interior lights aren't working could be the same thing. .
