E61 rear glass hatch locking fault

Postby TOOL » Thu, 18 Nov 2010 09:49:17 UTC

The rear glass hatch on my 07 reg E61 keeps opening on it's own. It does it when I'm driving, so the interior lights come on and then I get the warning that the boot is open. It's only the glass part, not the entire tailgate.

I can hear the electric motor winding, as if it's trying to open or close again and again.

Anyone know what the fault is?

Thanks!

Thanks for the reply. Is it the actual mechanism or the motor? Any idea what the part number was?

I came out from work tonight and the car was saying the clock needed to be rest as the battery had been disconnected. Car started fine.

Bit strange.

Sounds like the microswitch failing, they tend to play up before they fail totally.
Switch sits where you squeeze to open glass - below the wiper pivot.

Could also be the tailgate wiring loom whihc is also prone to fail, but I'd try the microswitch as a start point.

Went to start the car again today and the rear hatch popped open when I pressed the remote to open the car. The clock had switched off again too. No problem to start or anything like that

I'll try some WD40 when I get home.

Is this all related to the microswitch in the rear hatch glass?

Realoem says the rear hatch glass switch is discontinued. Presumably sold out from all the failures.

REAR WINDOW LOCK 51248218849

Do you think I could get it replaced free from BMW? It's out of warranty since May this year and I bought it used privately.

You can try the dealer for goodwill - I suspect they'll not be entertaining that idea wahtsoever for the value and type of repair this requires.
I'm confident it's the switch from what you outline - battery drain is also asscociated.

To prevent the symtpom, disconnect switch whilst you are sourcing replacement. They are typcailly on back order from Germany as appear to be a common compoenent to fail.

Nice one, thanks for your help. Mechanics I can do. Electrics and I'm easily lost.

£82.00 including VAT new apparently. Takes a couple of days to come in. Should be easy enough. Then back to the classic cars!

Do be sure to let us know if that's the culprit.

If its happening when driving it sounds like its the body control module playing up. The microswitch and rear boot button won't do anything once the car is moving as a safety feature. The BCM was replaced on my car when it started popping the rear window open while unlocking the car, also at times it would pop the rear parcel shelf up randomly but not unlock the glass of boot.

Body control module, eh?

Where is that situated? I had a fault come up on the car last night saying the battery was discharging while the car was stationary. Yeah the glass hatch sometiomes pops open when I open the doors with the fob too. It also sometimes refuses to open at all now.

Thanks for the heads up.

I ordered a new switch through Cotswold Group (advertised on here). I gave them a part number off realoem and they only wanted £25 delivered. Not sure they're sending me the right thing, but we'll see.

I'm gonna unlpug it to stop it for now. I'll update when I've fixed it or if it gets worse.

Cheers guys!

Its located behind the glove box. I also had the battery discharge while stationary message and occasionally a window anti trap failure message. They replaced the body control module and a module in the boot that wasn't going to sleep properly which is what was draining the battery. All done under warranty so I have no idea of the cost. The car was kept in over night to recode it so that wouldn't be cheap.

OK, I'll look into it.

I dosconnected the switch in the tailgate. Now the car thinks the boot is open and every time I pull away from the lights it gives me a warning. Annoying to say the least.

I can't open the hatch glass now either which would effectively resolve the problem, apart from the battery discharging and causing the clock to need resetting.

It's looking more and more likely it's going to have to go in and cost me some money.

Dont agree I had very similar problems as described and it would open on the move, replacing the tailgate lock module thing! solved it.

Whilst your correct in theory the BCM should hold it shut. I suspect that the tailgate had opened when it was stopped but gravity stopped any warning lights etc, whilst driving and hitting a pothole (not that we get any of these in the UK) would open the tailgate giving the symptoms as described.

The cost of the switch is probably less than the dealer having a look at the car

Yeah, I've bought the switch. Just waiting on the post now.

If that doesn't sort it, I'll have to look into other options. If I can't sort it, it'll have to go in.
If I can get the battery discharge issue fixed and stop the "boot open" warning going off, I don't car if I lose the functionality of being able to open the hatch glass. I've got the main tailgate.

Just want all the warnings gone and the boot to stay closed unless I open it.

For a £30k car, you'd expect at least that for more than 3.5 years............ (queue eyes rolling backwards)

So the part I was expecting was not what I thought I had ordered. What turned up was the little switch and handle that sits under the rear screen wiper. It was only £25.
I thought I was getting the electric motor that releases the latch fixed to the glass. Those must be the £75 parts someone else on here was talking about.
I thought I'd fit it and see what it does. Seems to have done the trick! :)
I don't get any error codes, the battery discharge issue has resolved and the clock doen't need resetting every time I get in the car.
Result.
Cotswold Motor Group who advertise on here were very quick in getting the part up to London. They didn't send the part I asked for, but I guess I got the right part anyway.

Thanks chaps.

Glad you got it sorted - the micrsowsitch which sits under the rubbr squeeze cover does fail quite commonly on these.

E61 Rear Glass hatch locking fault.
I have the same fault on my car and ordered a new switch from Cotswold yesterday Friday 6th and it arrive this morning Sat 7th.
Any one know how to remove the switch off the glass.
I have undone the nuts etc, removed the wiper but cant budge the switch.

Hi,
The switch is effectively held in by the rear wiper nut.
you need to get the rear plastcc surround (on the inside of the glass) off so you can reach the wiring connector. It just slides out iirc.
Mine needed a little cohersion as there was some corrosion in there.
You can remove the entire mechanism from the glass if you want.

I have exactly the same problems on my E61. Do you have the part number and a brief description of how you replaced it?
