OBC temp sensor and Map reading light

[Jhonno]

Right fitted my 6 button OBC 2day but the temp is reading bout 20 deg lower than it should... New sensor time or fixable problem?

Also how do you retro fit a map light mirror? I've got a leccy sunroof...

[A1BMW325iSport]

maplight mirror is easy, earth lead bolt to sunroof motor bracket, live wire connect to the green wire from sunroof switch

[Jhonno]

so the connector wont be there unless the map light was in the 1st place?

[A1BMW325iSport]

no its not mate, you can wire it into the check control wiring or the sunroof, i chose the sunroof wiring

[Richy325iTouring]

so the connector wont be there unless the map light was in the 1st place?

conector is in the speaker well on the passenger side

i just put nemos one in the 320

also with the temp sensor it sounds like you need a new one, think they are about 16quid from bmw

[Jhonno]

ah - so you'd need all the wiring from the mirror to the speaker well then?

damn i cut mine

just have to solder it in then

If you wire it in properly does it work all the time or only on the ignition?

[Richy325iTouring]

works with ignition on first click

[A1BMW325iSport]

like Richy says mine also works off ignition stage1
if you have leccy sunroof there is a Green sleeved wire that runs from accesory connector behind glovebox up the a-pillar then to sunroof switch connector - tap into that wire

ta fella

[Jhonno]

Hmm had a look at it today and i dont have a check panel which looks like i gotta drop the panel to get to the sunroof wiring..

dont know if i can be assed with that, anyone want a map reading mirror?

[Kedge]

I just ran the wires across to the interior light on the drivers side and wired it to the, doesn't need the ignition on either.

[A1BMW325iSport]

mate pull out the sunroof switch then solder your maplight live wire on the green wire on the sunroof switch

[Jhonno]

ah good plan batman

*goes outside*

[Jhonno]

ok.. how the f**k do you get the new mirror back in? is there a technique cause i cant find it

[Kedge]

Get one side lined up then lever the otherside in with i flat head screw driver, pushing in the end on the mirror.

Hope i explained that ok.

[Jhonno]

can that be done with no check control panel to remove and create a lovely big space to get to it?

[Kedge]

Did it with mine, one part of the mirror in the hole then the end of screw driver in the otherside of the hole pushing the spring in on mirror, then just try to push the mirror all the way in as you pull the screw driver out.

Making no sense at all am i

[johnono]

poke the new mirror in the slot one sided

then get one hand between the window and the arm ( to guide ) and the other to "twist" the arm in... need to give it some though fella

[Jhonno]

hmm given up for the evening.. gonna have me weetabix in the morning before continuing

(i actually gave up about 7pm but hey )

[A1BMW325iSport]

it comes out easier than it goes in

i took 3 attempts to get the mirror in try some copper grease on the
ends then put left side in first and use a fat screwdriver to push real hard
whilst pushing the mirror up hard at same time.

its a little barsteward but it will go in eventually

[Jhonno]

Your all legends!! Got it in 2day 2nd try..

Hadnt been giving it enough well in fear of breaking it. With a bit of brute force and ignorance (left side in 1st) it popped straight in!! Woohoo!! Now for the wiring

[Jhonno]

is it deffo the plain green wire and not the green wire with the blue stripe?

[Richy325iTouring]

mine went in easy

[sabrje]

All this is perfect timing - just bought a map reading light to celebrate passing the MoT first time yesterday....

So now I have a 'how to' guide as well - cheers

[A1BMW325iSport]

is it deffo the plain green wire and not the green wire with the blue stripe?
