Trunk lid grip button not working – DIY
 

For all the help I’ve received from DIY posts and videos, here’s my first attempt to ‘give back’….

Ride: 2007 Cooper S R56
Problem:
Rear hatch won't open via the handle on the door.
Pops open fine using the key fob.

On my 2007 Mini Cooper S (R56) the rear hatch / trunk lid failed to open using the handle on the trunk. It would only open using the button on the remote key fob.

It also seemed I wasn't getting the same 'feel' when squeezing the handle.
I had assumed (incorrectly) that the latch handle was a lever that pulled a cable attached to a lock mechanism. With only initial research I guessed one of the following:

1. Broken latch lever and/or attached cable
2. Programming option/error on the key lock function
3. Issue with emergency release cable

I started with #2, programming option.
I wondered if somehow the locking options were disabling the rear handle, even though the car was unlocked. I followed the owners manual (page 23) to set the Automatic Locking option to off - central locking system remains unlocked. No luck, and no change.

Next I checked #3 - emergency release cable - since it didn't involve disassembly.
Page 23 of the owner's manual also describes how to lift the rear seat to locate the emergency pull cable. I found the cable pull ring on the passenger side and pulled.
It worked, there seemed to be a reasonable amount of slack in the cable, and it returned when released. Again, not the problem.

I finally went after #1 - failure in the mechanism.
Once removed, I discovered the handle didn't attach to a cable. Instead it was connected to an electrical switch, probably activating the same motor circuit the key fob used. I tested if the switch was bad by jumping the leads at the connector to open the door. This worked, pointing to the handle switch as the problem.


The DIY for the testing and replacement follows….

Disassembly and Diagnosis
 

Disassembly and Diagnosis

Remove license plate and frame
Parts/tools: Phillips screwdriver

1. Remove license plate
2. Remove 2 phillips head screws holding license plate holder frame

Remove trunk lid grip

Parts/tools: T20 Torx screwdriver

1. Open hatch halfway.
   Makes it easier to get at screws, prevents grip from falling off
2. Remove 4 T20 screws. A little difficult to get off

Disconnect electric wiring harness
Parts/tools: Small jeweler's screwdriver

1. Place the screwdriver into the slot pictured
2. Push down, wiggle upper harness sideways to work the plug out
3. Set the trunk lid grip assembly off to the side on a protected surface
   (towel, cardboard, etc.)

Inspect the switch

On my Cooper it appears some plastic failed around the switch, either on the side clips securing the switch, the latch handle inside, or both.

Test the switch function
Parts/tools: paper clip, insulated pliers

The handle in the trunk grip is not a physical lever to a release cable. Instead it's a simple electrical switch. It appears to accomplish the same function as the key fob button, activating the motor that releases the latch. It's a good idea to test/mimic the switch function to make sure that's the culprit.

You can do this by 'jumping' the brown and blue/red wires

1. Form a paper clip to the width of the 2 outside contacts (brown and blue/red wires)
2. Hold the paper clip with insulated pliers, touch the 2 outside metal contacts inside the plug.
3. The hatch should pop open.
   If it does it confirms that the switch is at fault

Replace and Install

Now that you know the handle switch is at fault, here’s how to replace and repair….

Replace the trunk lid grip
Parts/tools:
Mini Cooper part 51132753603:
Handle, trunk lid, with lamp unit Chrome line exterior

Unfortunately you can't order just the switch - it appears to be molded into the housing.

Likewise, you can't even order the black plastic housing.
It has a BMW-like part number on it (7 151 140 405 014 50),
but I can't locate that part for sale anywhere (and no Google hits either).
A call to bavauto.com confirms this.

It seems the only option is to order the entire trunk lid grip assembly,
including the cosmetic cover - which you likely don't need.
These are your options, according the listing at RealOem.com :

• $94.52 Chrome line exterior 51132753603
• $97.37 Trunk lid grip primed 51132754240
• $185.51 Trunk lid grip painted (specify color code) 51130430312

Since I'll be reusing my perfectly fine cover...and I'm cheap...I went with the Chrome line exterior.


Swap cosmetic cover
Parts/tools: 2 flathead screwdrivers – one small head, one larger

Remove the plastic cosmetic cover from the old assembly:

1. Place the old assembly face down on a covered surface (towel, cardboard)
   to protect the cosmetic cover
2. Remove the cosmetic cover by *gently* prying it off the retaining clips on the black housing:
3. Start at one end (far right or left) and free it from this outer clip.
   Do this by lifting up on the tab with a small screwdriver
   while simultaneously separating the cover from the housing with a 2nd screwdriver.

4. Remove the series of inner tabs/clips.
   Place the small screwdriver inside the tab and push down slightly,
   effectively lifting the edge of the cover over the 'teeth' of the tab on the black housing.
   Simultaneously separate the cover from the housing with a 2nd screwdriver.
   http://farm6.staticflickr.com/5325/9...a1066a6c_o.jpg
   Work your way down the line to free all inner clips.
5. Remove the other outer clip as described above
6. The cosmetic cover should now lift away from the black housing.

Remove the cover from the new assembly.
Install the original cosmetic cover onto the new assembly:

1. Hold the original cosmetic cover face down in one hand,
   the new black housing in the other.
2. Line up the bottoms of each by aligning the bottom clips
3. Pop the tabs in one by one working from end to end

Reinstall trunk lid grip

Reinstall in reverse - very easy.

• Check that the rubber seal/O ring is on around the switch
• Plug electrical connection back together
• Install 4 torx screws holding the grip to the hatch/door
• Optional - test operation of the handle
• Install license plate holder frame, then license plate

Hopefully this is helpful, and I welcome any comments, corrections and suggestions.

Awesome timing. Wanted to tackle this project this week. Keep the posts coming!

GREAT write-up. This should be in the Gen 2 How-To section.

+1 Nice write up. And a great job on the walk through.

Yes the part number for just the Trunk lid grip base backing part does not come up. Its only as one full part. Popping the rear cover off is great for people who want to transfer the internals and save on painting the new one.

Thanks

Thanks OP for a great post!

This happened to my on my Cooper (also 2007) this past week. I tried the other options of reset assuming it happened when I unhooked the battery during a recent repair. After that I assumed the switch itself was at fault, but haven't dove any deeper towards its repair. Thank you for very detailed DIY on this replacement

Mods: Make sticky/ duplicate in DIY section

Thank you for sharing! I have the same annoying problem. I tried inspecting this myself but got as far as trying to remove that wired quick disconnect and could not get it. I'll have to give that small screw driver a try.

I've had the problem for two years! Finally got around this week to taking it apart to see what's what. Googling the part # led me to your thread. Thanks — great write-up. I'm sure I have the same problem.

As a follow up, since 'gkp' replied, I replaced my switch with a new one purchased from ECS and got it painted, installed it, and it works like new.

As a side note, it is very hard to remove the old painted part from the switch part. I was getting my new one painted anyway, but I tried to separate the old one regardless. I was not successful and broke many clips. I would set aside some money to paint the new piece just in case you fail at the separation of the old one like me.

Mine just split open as well. Thanks for the write up.

Get the CF handle, it's better...lol

The CF version does look very nice in person. :)

Hatch Handle
 

Hey Randy,

I just installed a new hatch handle due to a failing switch on my 09 Justa. I think you just saved me a lot of dough by DIY.

Thanks.
MIke

Nice :)

Had the same issue with my 2007 hatchback. Exterior hatch button no longer worked, and the lock was beginning to spontaneously unlock the hatch while the car was moving - usually while backing out of the garage. Fob button worked correctly.


Removed the exterior hatch handle and found the wiring connector was not fully locked together. Pulled apart without unlocking the connector lock pin. Suspect the contacts were just close enough to hit during car movement, which apparently triggered the unlock. Securely mated the connection and taped. So far, everything is working correctly.

Thanks for the write up and photos!

I found it was not necessary to remove the license plate or holder to remove the handle.

However, If you live where the roads are salted you should remove the plate and get rid if the rust on the captured license plate nuts yearly or they will make it impossible to change the plate without damaging the plate holder

I've been having the same issue with my 2010 justa - FOB works fine, but the button stopped working. Previously I opened up the switch and found the little plastic holder was broken and I was able to hold it with stings. It stopped working again, so I tried to test the switch using above method.

You can do this by 'jumping' the brown and blue/red wires

When I jumped the wires with paperclip, nothing happens. Any ideas or suggestions?

TIA

This write up was very helpful when I undid my rear trim. Thank you!

Glad you got it fixed and can use the trunk handle again. :)

I had an issue with my grip not working as well on my previous mini. It would randomly open while I was driving and you could hear it clicking all the time.

Took it to the dealership and had the grip not working on three different occasions... Turns out that there was a seal that was supposed to be there to keep the water out that wasn't there. (I wish I could tell you why)

They put the deal back in and no more problems.

I've learned that my minis (on #2) are like super models with severe arthritis... Nice to look at and they typically steal the hearts of men, but every now and again they have days when the most basic tasks are hard to complete.

I have the same problem. Will WD-40 do the trick perhaps?

I'm having an issue with the number plate bulbs not working tried various bulbs still no good tested the connector and I'm getting 14v there any ideas what the middle cable on the connector is for ? Cheers

sub'd for diy and part numbers later
the grip on mine (rubber/plastic) disintegrated, i can still open the hatch by hand if i can find the tiny button up in the handle.
is the exterior painted trim really that hard to swap over - are the clips just brittle and fall apart or just a pita to separate the two pieces?

Its can be transferred , do it when its warm and in the sun and the tab are more pliable.

The part number are linked above.
