First aid box (underseat storage) installation

Post by Zmeagol » Tue 14 Sep, 2004 20:46

There's no point stopping to help at an accident and not being able to find your first aid kit, so on newer models BMW decided to fit it under the passenger seat in a special storage box. The first aid kit and box is standard in Europe however I thought it would be worthwhile installing a second box under the driver's seat for storage of camera, Talkabout radio, PDA or whatever.

The cost is ridiculously low, just £8.60 for the box (p/n 52 10 7 044 958) and £3.90 for the Z4-specific support bracket (p/n 52 10 7 045 018).

Here's a side view of the box

And a view of the bracket showing the three screw holes

All you have to do is screw in the three screws and snap the box on, but the screws I had been given were the wrong thread. Working upside down in the confined space is frustratingly difficult and at one stage I was seriously considering taking the seat out to install the box!

I used a mirror to establish the passenger box was held on with Torx 30 screws, then unscrewed one of them and matched the thread with some loose screws I had around. Success!

Isn't this the standard BMW 'Goesunder' modification or does that one come with a hole in the seat and a china plant holder with handle :?
In fact I gather it would be more appropriate to put this on the passenger seat in certain owners cars :wink:

Interesting use of wasted space. I wonder if it would fit in a Z3.

My dealer actually carries these as a stock item! (Sytner Leic.) Tim, did you find out the bolt dia. for the fixing screws?

I'd be interested to hear is these fit in the Z3 if anyone finds out.

Good idea by the way.,

I have just collected an additional 1st aid box. Apparently the same box is a fixture in most current BMW models. I tried to find out if it would fit the Z3 but no info on the system! As they are carried as a stock item it would be quite easy to offer one up to a Z3 seat at a dealer.

I have just been told by my brother
that he has purchased one for under
the drivers seat for £12.50 complete
with fixing bracket from the dealers
What a bargain
I am going to see if it will fit into my MR//
before he fits it to his car.

I got the dealer to fit a 1st aid box under the drivers seat as part of a new car "deal". I fitted one on my 1st Z4 myself (quite easy). BMW's instruction is to take the seat out - not necessary, and in this case expensive for them!

if anyone needs screw diameters - I used 6mm x 25mm screws from B&Q to fit the bracket.

I have the M seats and I have a first aid box under the passenger seat, so would imagine it would fit under driver seat no problemo :D
