The Bad: the trunk latch on my '03 LTE self destructed a couple of weeks ago and I knew that it would at some time because of the excessive friction encountered when latching it.

The Good: I purchased an Interstate Star Sport (Diamond Coverage) extended warranty from Bob's BMW and it covered the replacement of the lower trunk ($938.44 installed less my $50 deductible) absolutely hassle free.

The Bad: No question, this trunk latch will self destruct at some point down the road (got 3 1/4 years and 25K out of the first) as it has the same excessive friction as did the original.

Temporary Solution: I have removed the left-side latch pin from the top trunk as this is the side that broke and still exhibits excessive tightness.

Potential Solution (your thoughts requested): remove the two trunk-top latch pin holders (they appear to be pop riveted in place) and then shim (about .030) and then re-rivet into place. Do you think this would work?

That would work fine. But I think you get the same result by using a Dremel tool on the moving parts that latch over those pins. Just shave .030 off of them and go from there. Worked for me.

I think there is a back-up plate inside that the rivets go through. If you drill out the rivets and the plate moves around, you would have a very difficult time getting it back in place and supported to put the new rivets in.

A better solution is to Dremel off some of the pin contact surface of the latch claws to loosen up the grip. Several have done that.

Hmmmm - a well crafted letter to all the companies providing Extended Warranty policies that covers the trunk latch, would seem to me a worthwhile endeavor. And prolly a few of the major BMW dealerships would like to know about the Millenhaus product too!

I watched the first versions being made here locally and wuz definitely impressed with the work and time put in to produce a quality solution to a 'too frequent' problem. And one that offers a lifetime warranty, right??

BMW oughta outsource to Millenhaus for this item. And BTW, what the heck happens to the lower trunks that the insurance companies settle for??? :rolleyes: :bmw:

Latch

Dave's solution is a good one, I like mine: Just swap out the 5mm pins for some 4mm pins and you will never have latch trouble again.

Did all the mods to the claws and took off a few thousands off the latch pins and closed with the utmost care on my 02 and it still cracked and turn to S**T. Waited for one of our LTers to CNC a replacment. Seems he lost interest or got side tracked. Wife saw the frustration every time I used the truck. She took it upon herself and ordered one from Millenhaus for my last birthday. Top notch craftsmanship all be it a little spendy. Still cheaper than buying a whole bottom trunk assembly. Works great will recommend too anyone who asks........

Trunk Latch

That price for the Millenhaus doesn't seem so bad; I paid $275 for a stock (and therefore weak) used one off a wreck!

The dremel tool will take the material off, but it leaves too rough of a surface to not wreck the pins or cause excessive drag. After using the dremel in the corners remove the whole claw and put it in a vice with a couple pieces of carap wood or paint sticks against them so the jaws don't bite into them....have it premarked to take off about .030...and use a hand file going lengthwise on the claw to remove any rough spots caused by the dremel. Actually the material is quite soft...you can use a round file in the corners if you have one.

Trunk Latch Broken

My 2002 LT Rear Trunk Latch broke this week. I contacted Morton's BMW and was told that my Pinnacle Extended Warranty would not cover this. They are checking with BMW to see if they will partially cover (probably one half) a new box and latch. Extimated price of box is $800. Bike came off factory warranty last November and odometer is approx. 30,000 miles. I wonder if this is worth it or just use the money towards the Millenhaus latch? Anyone have experience with Millenhaus latch and how hard is it install? Thanks. John Hieronymus

It's not the dremel tool that makes it rough - it's what you use IN the dremel tool. Mine polished it to a mirror finish - just have to use more bits than what comes with the basic kit.;)

That depends totally on what tool you are using in the Dremel! I have done a lot of work with them, and if you use a fine grain grinding point for finishing you can get a much smoother finish than the stamped stock finish.

I would use a carbide tool for roughing, then a fine grinding point for finishing.

OH yea...I forgot to tell you....after using the file on the claw I used 600 grit wet sandpaper on a paintstick with oil on it to polish it to a smooooooooth finish!
