B58 Engine- Oil Filter Disintegration

[ManOpener]

My M140i went in for a while-you-wait service today (it's first), however on removing the oil filter it was discovered it had broken apart in the housing. So now they're doing some remedial work on this (replace filter housing, presumable flush to ensure no crud in the oil system). Apparently there's a Technical Service Bulletin on it, so it seems like it's a known issue, but I can't find any information on either the bulletin or prevalence of the issue anywhere. Repairs are being done under warranty but I'm a little concerned that this might result in longevity issues further down the line- I've not seen any signs suggestive of anything further being wrong but I can't imagine either starvation due to flow blockage, or filter particles/components being in the oil system are going to do much good.

Anyone have any further information they can share?

How many miles since the last oil change?

Not surprised and far from the first to do this, but it seems worse on the B58.

Would be worth at minimum changing just the filter on an interim level between the extended services.

About 13k- variable/condition based.
I'll probably move to annual/10k servicing for peace of mind anyway.

Well worth it. BMW filters often collapse if left for the recommended interval.

Thread revive...

Just had this happening to my 340i. They broke the oild filter housing during filter removal... (odd, but seems a bit common). Car has had an air and oil filter change last year and is on 40k.

This was yesterday, advised part needs to be ordered, etc. So today rang for update and was told it is quite a substantial job 4-6h work... I think typically dealership bull... meaning ooopps we forgot about your car, we will start on it now.

Anyone had experience with this issue? Also, how substantial is the job? To replace housing? Lots of parts to disassemble?

Thanks

In my case (as the thread OP), the car went in at around 9:30 for a while-you-wait.
About 10:30 they reported the issue and sorted transport for me to get back to work. Also sorted a hire car
Around 17:00 I popped back to grab some bits from the car, it was stripped down at that point.
They'd finished by around 1:30PM the next day.

4-6 hours of actual working time sounds about right. Don't know about part availability though.

Thanks. Just got it so all good.
Any lasting issues on yours? Mine feels ok for now.

Nothing I've been able to discern, no. I've probably done about 1,500 miles since the service and it's been impeccable (with the exception of getting a stone caught in one of the rear brake guards, which was creating the most dreadful grinding sound!)

This ^ no fault of Mann or whoever the OE filter supplier is but just stupid stretched service intervals , see this on various mainstream manufacturers cars nowadays , Vauxhall & VAG vehicles for example I would want something in writing as I fail to see how they can guarantee that they have removed all delaminated filter material or debri from the whole oil system inc any damage incurred from the unfiltered oil thats already passed through the oiling system already

If the collapsed filter was discovered at service, with no other symptoms or damage, would the Dealer just replace the filter and not tell the customer?

Easy way out.

Yes.

[Sardonicus]

Agree with the last two posts

[AlwynMike]

And, as the card carrying cynic continues....

Take the top off the filter bowl to check - find filter collapsed.
Can't/daren't put it back to take it to the Dealer.
Said Dealer will not entertain a warranty claim as a non BMW person has been working on the car!

Catch 22

Maybe when mine goes for its service, I'll ask for the old filter - but the cynic says I may not get "mine" back....

[DailyHack]

curse you long service intervals if this was the case....

seen this happen a few times, albeit on the older E'series vehicles, one stuck in my mind, it was a 120d 2012 plate, the oil filter was stuck in the housing due to breaking up, we had to chisel it out!!, oil hadn't been changed or filter changed for 25k+ miles, one off maybe - but not as rare as people think.

Another example of great BMW design. Just focusing now on selling the cars new with no consideration for longevity. In fact, the sooner it needs repairs after the warranty has run out, the better for them.

Gone are the days of build quality that owners aspire to a BMW.

Quite the thread revival - did you have this happen?

I've read a few things about the B58 filter and how the filter comes apart on removal, and the bottom of the filter needs to be removed from the housing to be able to replace. Hopefully BMW have sorted it by now though.

It’s not a new problem. It’s been happening since the paper filters were introduced, I think back in the M52. It’s not hard to remove the broken off base of the filter, a pair of long nose pliers do the trick.

This was a problem with pattern part filters on VX220 NAs back in the day. For whatever reason some pattern part filters were fractionally too long and were slightly crushed when the lid was screwed down. This led to the filter shedding fibres which lodged in the nozzle that squirted lubricant on the timing chain leading to premature failure of the chain. The engine was fitted with a bigger nozzle on production which cured the problem. I don't know if your engine has a chain or belt and if the former does the squirty nozzle - assuming it has one of those too - have a big enough hole so this is just background FWIW!

Looks more like someone searching for posts, however old, to be critical and how good the good old days used to be.

Having owned BMWs for over 20 years, left to go to Tesla for a while, I’m now back. Whatever you think of BMW engineering and service I can assure you there’s a lot worse out there.

A B58 engine willbe on my drive next week in a 840 GC and 8m not worried in the slightest
