RF receiver replacement

[Tins]

Got to do this. Has anyone had any success doing this without removing or cutting the headling? Can you get at it though the light fixture? My car doesn’t have a rear sunroof.

Yeah but, cant you just disconnect the old one and fit a new one in behind the glove box?
Wont have the same range, and a little bit of wiring involved - but a shirt ton better than key hole surgery.

Not a bad idea, and it can’t have less range than it does now. But I’m just being lazy, don’t want to pull the lining.

I think we need to do this on nephews D2 soon. not urgent, but I had a poke around the web for info on the topic.

One chap on the 'tube' with a username related to cats(as I recall) had a video up on how he did it through the narrow gap between the headliner join. Not easy to get to it, but he's as old as us, and managed it.

First thing I'd be inclined to do would be to determine if there is a signal getting to the BCU before condemning the RF box, as this is easier than going to the trouble of getting to the box.

The wiring diagram for the rf box is a cryptic mess. Wires not listed, plugs not listed .. it really makes no sense what RAVE shows, nor why it's wired up the way it supposedly is.

The only thing that does make sense is that the Purple/Grey wire is the power from the BCU to RF box, and that the Black/Brown wire is the RF box signal back to the BCU.

Both those wires have intermediate connectors(this is part of the doesn't make sense comment) .. one on the LHS A pillar kick panel, the other on the RHS a pillar kick panel.
(why wouldn't they both just track down the same path to the LHS to the BCU?)

Earth wire is connected down the back load area(LHS). Black wire at the RF box is shown in the circuit diagram, and shows connectors, but wire is not shown in connector view at the RF box.

It's not that bad. You have to remove the rear sunroof's outer trim and pull the headlining in front of it just enough to reach the receiver, doable in situ with a bit of fiddling... just fix well the eyelet connector under the retaining bolt to have god earth, i dont have better quality pic

Mine is an aftermarket sunroof but I’ll take a look.

Juat realised that you dont have rear sunroof then my reply is useless[bigsad]

Mines been flaky for some time, and now I get "No keypress detected".or similar. What I have found out from my own rabbit hole exploration is that condensation is the enemy, and mine has had plenty of that.

[AK83]

my apologies. I thought the headliner was split into two halves.
video I saw on you youtube must have been sunroof type or something, which doesn't help you.

for sure check connections up front first, considering the fusebox issue you recently sorted.

[PhilipA]

If you do not have a sunroof at all you just remove the trim around the LH front door and pull the headlining down a bit. You can then reach in and remove the receiver without losing too much skin.
There used to be a broad range signal detector that you can check your transmitter with on ebay.

I am going to try that method even though it has a front sunroof.
I want to get a tester like that but for home entertainment remotes. Trouble is, apart from Apple stuff they’re all IR, not RF.
Neither key is detected. I have a third one somewhere.

[Tins]

Hmm. Given all the craziness that the car was exhibiting recently perhaps I would be wise to attempt reprogramming them before I commit to surgery. All the BCM functions went nuts until I traced it to corrosion in the interior fusebox. It all seems to have reverted to normal except for the key for stuff and perhaps the fuel gauge.
Worth trying. I did it already but that was before I did the fusebox. Thing was so weird that I sorta lost track of what I was doing.

as above phillip said^^

bit of a body contortion to lean over the headlining without putting too much weight on it but easy enough

not sure about this bit but perhaps good to disconnect battery negative before swapping out the receiver. swapped mine out and went to detect the keys with nanocom but the fuse for diagnostics (fuse 20) had blown. put in a new fuse and all good again and nanocom powered up and detected keys all good. maybe just coincidence? but nanocom was working prior to swapping out the receiver (and wasnt detecting the keys hence the swap).

Oh yes, batt -ve off for all of this kind of work. I'm hoping the front sunroof doesn't impede me pulling the lining down. I'm still going to try reprogramming first, only takes a minute. Just want it to stop raining...

[Tins]

That was fun..... The aftermarket sunroof blocks access to one of the bolts. I also noticed that there was an earth wire not connected. Dunno. Anyway, put the spare receiver in on the one bolt I could get at ( with the earth wire ) and hey presto, two working plibs...

I'll sort it properly when I do the lining... when it's warmer and drier...

........two working plibs...

Wots a "Plib" in your neck of the woods? Look it up here:

I know what you mean, just never heard them called this before.

Actually, neither had I until this particular journey into the wilds of the internet. I've always caloled them remotes, or sometimes fobs, although I used to think a fob was one of these:

I'm not entirely sure if I like the definition you quote. In my case the first is rarely followed by the second.
