Few electrical niggles

hunker7 · #1 21st November 2018, 05:01 PM

Hello fellow owners, have few electrical issues on my newly acquired D2.

1. Trip computer won't register that boot is shut? Where is the sensor for that, can't see one separate, is it part of the latch?

2. Lights won't come on in the boot, no +12v to the bulb holder? Could be related to above?

3. When I unlock the car only front interior lights come on? Rear comes on when I turn front on, but they won't come on with the rear switch?

Makes sense?

4. Now it's bit chilly outside, trip computer screen is very dark? Once car warms up it's nice and bright?

TIA

The display being dim when cold is a common problem. Without replacing it (and there's probably no part available) I dont think there's any solution.
The interior lights and locking mechanism and detection systems are all controlled through a single "Central Locking Alarm System and and Interior Lights Control Module" in the boot on the left side near the wheel well.
The boot lid alarm switch is in the latch mechanism and feeds into this module.

Finding the Module would be a good starter for ten here. As well as getting VCDS scan

I'll get it scanned tomorrow and find where the module is and take it from there. Seems like all the issues are related

No errors on vcds for central locking

Well, i guess that the boot being detected as open is not a "fault" as it is just recording what the sensor is telling it. Therefore its a faulty sensor.
The interior lights issues will probably just need some patient fault finding.

I'll start with replacing the latch and take it from there.
