BMW Coil Spring Information

Does anyone know of a solid, detailed, information source for the differences between BMW OE numbers for coil springs?

I’m specifically looking at BMW E9x springs, and finding multiple OE numbers for the same models. Example: 3 different OE numbers for the front springs on a 328xi. I know that differences like sport suspension, comfort suspension, mid-cycle refreshes, and what not can create the need for different springs. What I want to know is, where do I find out what spring (OE number) is linked to what vehicle/characteristics? I’ve looked into several aftermarket retail sites, none of which got detailed enough, and the forums haven’t been much help either.

Anyone have a good source for OE part information, or at least detailed differences between E9x models?

Did you look at realoem.com?

Yeah, it doesn’t really have the information I’m looking for. It kind of has the reverse of it. I want to search all the models for a given OE number, down to specific options, characteristics, and differences. RealOEM is more about finding the OE number to match your specific vehicle.

regular, sport and m sport... so heres the easy way to find what you want... go to ebay and find the last 7 of the vin for the type youre looking for, plug that into real oem and it will only give you springs for that car. as far as physical differences and rates, no idea...

That’s definitely useful information. Unfortunately, I’m trying to go the reverse of that. Using an OE number to find all the different models that spring matches to.

That’s nearly perfect! It just needs each sub-model/option with the corresponding OE numbers. lol

I know who makes them for BMW, however there’s no database beyond BMW’s own internal one for all of the info that you want.

thats what you pay for, what you got was free... i think its hollander exchange thats gives you specific info

Precisely. I know roughly what car, but not the specifics about it.

For example, the following OE numbers all fit an E90 325xi:

31 33 6 769 915

31 33 6 769 916

31 33 6 769 917

But I can’t figure out what the differences are between each of them.

Honestly your best bet is to stop by a dealership. The techs will have a proprietary database much more complete than anything you might find online. I can’t speak to how willing they’ll be to give out free advice though.

Have you looked at RealOEM ? You can’t order parts there but they have detailed listings.

What question are you trying to answer here?

I have, and they don’t get detailed enough for me.

I’m looking for the differences between and what models three different OE numbers for 325xi front springs fit.

Standard, sport, m sport...

The difference between 3 part numbers isn’t really a purpose unto itself. Why do you want to know this difference? What are you looking to do with this knowledge? I can try to help answer that.

Sometimes there’s a change in factory or supplier or something like that which gives a new part number to the same part.

I can tell you that the E9x awd cars had no sport suspension option, even on the sport package. My E92 335i xDrive M Sport has the same springs as any other E92 awd 335.

So if you’re looking for a way to upgrade your springs to factory sport package springs, no such springs exist.

I’m trying to determine the information for a project at work. Haha

Right, but I need to find out which is which. Haha
