    Hmm, this is annoying.
    I've just been outside to top up the windscreen washer with fluid and the bonnet catch seems completely jammed.

    The bonnet 'pops' correctly when I use the internal release, but the second release under the centre of the bonnet is just jammed solid and won't budge at all.

    I've sprayed some WD40 and will leave that for a while, but short of visiting the the BMW garage, is there anything I can do?

    *edit*, it's actually an E91, but brain fade made me put E90, I can't imagine there's any difference.

    Try adding some sound deadening. This will improve the build quality of your Bimmer and may well cause the spontaenous release of the catch.

    Failing that ask someone with strength to help you.

    That's what you get for having a car you don't need the bonnet up every 5 minutes on :D ...as for you predicament, well you could try fashion some sort of tool out of an old coat hangar or something to get it open, probably doable.

    Don't bring your BMW hatred in here my friend. My gf has a Golf you know!

    It's not about strength either, it's just solid and the inch or space doesn't exactly give a lot of wiggle room.

    I agree. I was just thinking today that this has been the most reliable car that I've ever had, and then this silly thing happens. Of all the things that can fail, a bonnet catch should be something that's been perfected by now.

    Hit it with a hammer? :D

    I don't mean to sound insulting but are you sure you are trying to open it correctly?

    You're right, I did question myself about this, but have opened the bonnet on numerous occaisions before and not had this problem.

    As I look at the bonnet the secondary latch is directly under the BMW badge and is yellow in colour (and I can see a spring that's directly attached to the latch), but it doesn't have any play in it at all.

    I would consider a hammer, but there's just not enough room and I don't want to damage anything.

    What if you get someone to sit in the car waggling the initial release whilst you simultaneously waggle the bonnet release?

    Whats the catch look like? I mean it's mechanisim? If we know that and a picture of the current "popped" up state of the bonnet we may be able to formulate a plan.

    This happened on the e46, pulling the grille lever really really hard did the trick. That said, it did at least pop out, wasn't totally solid.

    Squirting some oil and shoving a screw driver in there did the trick on my old E61.

    If the catch in the car is loose, you have a snapped cable. My e39 did this.

    Bit of a bugger to fix as BMW made it pretty hard to get at the catch.

    Are you pushing/pulling it the right way?

    The lever inside the car works perfectly - it's not loose and pops the bonnet up. The lever under the bonnet is simply jammed in it's 'up' state - that is that usually I would place my hand underneath the bonnet and pull upwards (it's a lever, not a pullable handle) to release the bonnet, but in its current state it won't lower.

    I could try levering it down with a screwdriver to see if that frees it, and as its been soaked with penetrating fluid for a few hours I'm hoping that it will be fine in the morning. I really don't want to have to go to the garage with it .

    *edit* further googling of 'e90 bonnet catch' has this very thread as the second hit - where it's now obvious that I've spelled 'bonnet' incorrectly in the title.

    Doh.

    How far up is it locked? Does it have a red button on the lifters?

    Hmm, I'm not sure. I can pull the bonnet up a little bit (as you normally can when you've released it internally first) and all I can see is the main latch mechanism, and the yellow lever that I would usually push upwards towards the top of the bonnet. I can't see anything red.
    It looks as if the yellow lever hasn't got any further to go up, so appears to be stuck in the upmost position. I'll see if some gentle levering will work in the morning.

    Send me your last 7 digits of your chassis number.
    I think I have 2 new catches for E90 I could send you free but have to check fitting first.
