Default Same problem resolved with replacement bumpers

Boy this is an old thread...

I had the exact same problem. I didn't understand how it could make a difference either. I changed the bump stops very easily and it closes and stays closed without issue. It was really cheap to do too. They unscrew from the edge and the new ones screw right back in. You may have to adjust the depth of the little bump stops a little, but you could note how tall your old ones are before you put the new ones in and you should be set.

That's what the problem is - and this is what fixes it.

JUST DO IT.. you'll be happy with the results.

2 x part number 51-24-8-137-994 on order from circlebmw.com

By the way, I can't say enough nice things about those guys. Very reasonable prices and shipping. Much easier than waiting in line at my local dealer and being tempted into buying a new car!

And thanks again to everyone on this board - what a great community!

How on earth do I get out the old ones? They just turn in place and don't seem to unscrew!

  • If you are wondering about whether or not to buy snow tires, please review the dozens of threads where people caused thousands of dollars of damage in a light snowfall at 10 mph.
  • If you are thinking about buying an M3 because they can now be found pre-owned fairly inexpensively, please review the threads explaining how expensive the maintenance is. Plan on spending $2,000 or more per year on routine maintenance.

Notice the spiral cut on them - counter-clockwise rotation will take them out.

I finally got my old ones out by spinning and pulling with a pliers. The new ones look almost exactly like the old ones, but the spring mechanism seems to work a lot better on the new ones. I am 99.9% certain I already had the new part in there. Hopefully this will improve things. I hardly ever use my trunk and the problem only happened every so often in the past. If I am trouble free by the time spring rolls around, I'll call this a success.

There is a quite visible difference between the old ones and the new ones..

The old ones are simply screw in rubber bumpers.

The new ones are the same bumpers with a spring loaded piston that comes out of the center about 1/2" (1/4" in diameter or so..)

I can't imagine not spotting the difference.

What did your old ones look like and what do the new ones look like?

They both had the spring piston, but the spring piston on the ones I removed was not nearly as strong as the new ones. I'm sure they were the same part number, but the new ones were - well - newer, so hopefully the stronger spring will help things. For the record, mine is a 5/04 build date and I bought the car used, so it is possible the prior owner already tried this fix.

Unscrewed the old rubber bumpers, screwed these in - and it works great. Now when I pop the trunk, it pops up about 1/2" - and the latch fully releases.

I found a 21mm deep socket was ideal for removing the old one and installing the new ones - it had just enough grab on the rubber so they could be turned. I used a bit of GummiPhledge (silicone grease) on the threads on the new ones so they would go in easier.

Attached are photos..

The first photo is the new one on the left and one of the old ones on the right. The second photo is a new one installed in the trunk lid.

On a difficulty scale of 1-10, this is a 1..

you guys are great im having the same issue 02 vert im ordering those parts asap thanks
