Does anyone know what this part is?

[Deepseaskateboard]

I have been scouring real oem, but have had no joy.

https://www.realoem.com/bmw/enUS/partsearch?id=LL32-EUR-03-2012-E89-BMW-Z4_20i&mg=&q=Battery

I am looking for the part name or number of the negative terminal cover.

I have attached an image of one (circled in blue)

Does the part have a number on it?

Thanks again!

Mine doesn't have one, it's bare. It also looks like it never had one TBH.
Are you sure it's not only specified for other markets?

Isn't that the IBS (intelligent battery sensor)?... correct me if I'm wrong

Do you have one on yours?

Pondrew I think you do have it.... just the plastic cover is missing? Is that the original battery in the car?

Yes mine has the cover missing but I thought that was what DSSB what after? :?
I'm presuming it is a replacement battery and the terminal cover was broken or lost when replaced.

It looks as though this, together with the IBS, is a component part of the negative battery cable package (61129249103).

If so, your best bet is probably a breakers yard.

Ah great, does it just clip off, and on? Or is it a sensor or more complex part?

I presume it’s like the red one, just a plastic cover?

 

[Deepseaskateboard]

Ok, mystery solved.

There are lots of these on ebay, it’s not a specific E89 part… looking by eye, and reliant on German standardised manufacturing!

Sometimes it’s about the terminology used to search, so thanks Conrod for the suggestion.

For anyone who hasnt got one, take a look at the ebay link, or search for similar items.

I do have the sensor, but no plastic surround, I managed to source one for £9

I will post a picture if it fits!

 

[mr.tourette]

Need to check mine now :lol: not sure Ive noticed one on mine either.. might be wrong though

Well done finding it. I don't want to seem difficult and am genuinely interested why you want one, though, when it serves no useful purpose whatsoever. The negative terminal on a DC battery is an earth terminal. The other end of the neg terminal cable is bolted to the floor of the metal boot (without any protection) about 10" away, so I am at a loss as to why the plastic shroud on the terminal is there TBH .

It’s to safeguard against anything shorting between the positive/negative terminals to avoid a “Chernobyl” type catastrophe

There is a dirty great black steel bar between the two terminals, which is directly connected to the body of the car,; so in effect is the same as the neg/earth terminal. That's not insulated, nor is the actual battery neg terminal, as this plastic shroud stops short of the terminal. Also, the positive terminal is completely shrouded by the red cover, so I can't see a problem. Again, I am not trying to be difficult, just interested (as I have to be very careful these days not to upset anyone)

The positive terminal cover could fall off

I figured why would they put one on, if it wasnt important?

It’s not mission critical, but it was bugging me that I didn’t have one!
I had a few small jobs on the car which needed doing, like the fuel cap tether, this is just another of those small jobs. It keeps me occupied! Haha

Fair enough. That's reminded me, the fuel cap on mine is knackered aswell.
