B58 oil filter disintegration

[sjb993]

I have read various reports of the oil filters of B58 engines disintegrating. I would be very garteful if somebody could enlighten me as to the current status of this problem. If it still exists I would like to get it sorted before the warranty on my 2021 build car expires later this year.

TIA

IIRC it's not too bad now. Don't see many posts at all over on Bimmerpost forums any more...

My pal had a fair few M3s and M4s in with the issue but soon got them sorted and cleared.

He used Hengst and Mann filters with zero issues and no need to get the housing replaced etc...

That's good to hear. 👍

Cheers.

They don’t just disintegrate in use. There have been instances of the cylindrical filter breaking into 2 parts and leaving part of the filter stuck in its housing when being changed during an oil service.

There’s not much you or your warranty can do till it happens which (I think) is fairly rare. I haven’t had a problem so far and I’d fight very hard for a dealer/warranty/BMW to rectify it FOC if it does ever happen.

It was the OEM BMW filters at fault wasn't it?

This …. I get my oil changed every 12 months (so five times now) and it’s not happened to mine (as far as I know!)

Thanks for the responses.

I did some more searching and came across this two-part video which shows what the problem is. Unfortunately it seems that it's still a matter of luck whether or not the filter breaks. I would have expected BMW to have come up with a fix by now.

Yeah; that's mentioned a lot on the Bimmerpost forums (a wealth of knowledge on there etc; worth a look)

Ass aid it was the OEM BMW filters that were at fault; some made by Mahle and the other Hengst I think it was what my pal said; but they used Mann/Hengst & Mahle filters and haven't had any issues, at all...

No idea if it was a manufacturing fault or fitment fault etc; think the bottoms dropped off them in some examples leaving a pile of cack in the filter housing!

Is there an easy visual check that you can do to establish what type is fitted? I'm looking for an F32 440i and would like to quickly establish if a car has the affected component so I can swap it out as a preventative measure.

I think it's getting better - the filter came out fine on my old M140i when BMW serviced it.

I doubt the very long service intervals help - my M140i did 19k before it decided it needed a service and because I bought the service pack, I had to wait.

In the second video he shows a Mahle one that's worse than the OEM one. He also said that someone else had found out that Mann and OEM are made by the same company in Tunisia.

OEM filters are either Mann, Mahle or Hengst - therein lies the issue... But they've had LOTS of time to rectify this and make the filters better

I haven't seen a recent post about it at all TBH - then again I've not looked either

Just swap it anyway, filters are about a tenner and easily accessible. Job done in 5mins.

Thanks. I know sod all about cars beyond the usual stuff like bulbs, fluids and typre pressures, so I had no idea it would be that easy. Seems like something to just do periodically if there's even the tinyest chance of it failing and causing a larger problem.

Yup; back of the engine on top; just need a 32mm socket IIRC

Yup; here you go: https://f30.bimmerpost.com/forums/showthread.php?t...

Shame the B58s don't have a dipstick like the diesels do; drain it via that then with a Pela pump etc

No. Have you not bought one yet?? How LONG have you been looking now?

I started gathering information around late summer 2022. Ducks were in a row financially by early 2023. Saw the perfect car but a nine hour round trip, weeks of train chaos and someone else beating me to it thwarted that one. Things have been a little lean on the Snapper Rocks Blue 440i front ever since. There are a couple of BMW AUC examples currently that tick most boxes, but one is on the pricey side on account of only having 8k miles and looks like it's been living on a farm judging by the amount of dirt and shrubbery tucked into its nooks and crannies, while the other is in Northern Ireland while I'm in West Yorkshire. I'm in no great rush anyway.

Just pulling your leg. Hope you get sorted. I’m in West Yorks if you ever need to compare anything.

If it’s going to fail it fails when it gets changed. It’s the action of taking it out that causes it to fail.

I too had a service pack but still had the oil changed at 12 months and then the service at 24 mths
