Hello

just changed the two boot light in the back “door”, but still not working. I ordered the factory OEM type.

Any idea or any standard issue around this?

many thanks for Your help!

Sounds like your problem may not be the bulbs. Did you check the bulbs you took out?

 

I would say you need to need to do some poking around with a multi meter and see if you have power at the bulb holders and go from there. I presume the light get power from a microswitch in the boot latch which may be faulty or it could be a broken wire where the loom comes into the back door

Here you go:

 

Thx i will check that and measure it

In the meantime i figured out, that the rear trunk opening is not visible in the dashboard, that could be one reason that the light is not working there.

 

do You think the change of the lock in the back could solve the problem? How is that part called? I could not find it

 

any similarities?

Personally, I'd be checking fuses and the like before straight up replacing parts and crossing fingers.....

The microswitch in the boot locking mechanism are well documented as being a weak point.

 

The lack of a dash warning to signal the boot is open is another telltale sign.

 

The car basically doesn't know that the boot is open, the microswitch isn't telling the car it has been activated.

Are You referring to this part?

Yes, that's it.

If you have a continuity tester, you can check the operation of the switch before committing money to a replacement latch. Unplug the connector and check for continuity between different pins: use the diagram wokwon posted earlier in the thread to guide you.

 

If the switch checks out ok, I'd move on to checking the wiring from the tailgate to the body: if that's cracked it would certainly get in the way of things working as they should.

Have the same issue with my boot lights - no downlights nor torch and Maxidot dash display not registering boot up. Car locks within minutes and alarm activates. Have followed continuity steps here using Wokwon current flow diagram and get earth rail at PIN 1 of Rear lid light (W51) but no positive at PIN 2. Indicates to me that boot lock micro switch is working otherwise there would be no earth continuity so something going on further up the chain wherever connector T5v terminates. Can anyone post the page of the wiring diagram that Track 363 points to? Would like to find out which control unit T5 plugs into and its location. Hopefully that page has a diagram showing torch light connections which are also missing off the above schematic. And would anyone know if there is a sense wire that triggers the boot open Maxidot or is that triggered off the same circuit once it's active ?

I initially thought fuse but like everyone else here I can't find a reference for a fuse for these boot lights.

Would be grateful for any help. Many thanks.
