Take a look at how much the oil cooler is beat up after only 1,200 miles! Scary.

My tech said he just replaced a G80 with a blown engine because a rock punctured the oil cooler. BMW wouldn't cover it under warranty because they said the guy drove for 6 miles with a check engine light on. Fortunately the owner's insurance covered the cost.

I’m planning to go with the mishimoto. The Zunsport looks like it’s out of stock.

I think maybe the triangle holes in the mishimoto might be big enough to allow smaller rocks and debris in? I was considering also adding some type of mesh screen.

That's kind of what I'm thinking right now as well. I bought the Turner skidplate for my F87 because when I bought it, the oem one was completely destroyed and I heard horror stories from people around me who had issues with oil cooler punctures. I remember scraping on some deep dips sometimes and was always worried but it protected the oil cooler and barely left any scratches on the Turner piece. Maybe a hybrid solution with the Mishimoto and the Zunsport would be the best option? The cooling "loss" from installing these covers has to be marginal and completely negligable, the holes are big and numerous enough to keep the rocks out but still allow for sufficient cooling. I feel like the Mishimoto/Turner options are more meant for tanking scrapes and hits while the Zunsport focuses on deflecting debris. The latter is made with stainless steel, so the mesh has to be pretty durable and strong. I doubt a rock would destroy it even at highway speeds, granted it's not a fucking boulder.

This is absolutely a design flaw that would have cost BMW probably close to nothing to implement a fix for. Who thought having a fragile radiator at the bottom of the car with no protection was a good idea? BMW knows that the owners of these M cars aren't buying them and driving them on perfect roads with no rocks or debris. It's not some showroom masterpiece, it's a car ffs, and a car's purpose is to take people from point A to point B and the chance of there being no road debris or rocks on a public road might as well be close to 0.

Very sad that BMW really couldn't put something like the Zunsport cover from factory for all of these exposed radiators. Sorry this happened to you OP, keep us updated and I hope everything goes well man.

You bring up a point I had thought...small items can get in that may not damage the cooler but will debris build up in the plate?

Interesting that insurance as an industry is accepting this risk and associated cost vs telling the makers to mitigate it at the factory. Ridiculous this all is.

As stated above in another post, this is a road, public road car. The design of the radiators, all of them open up to damage and critical in nature.

if the chances are of a small rock doing damage is already pretty low (but clearly a real problem) stock, then i feel like the chances of it getting through the mishi shield without significant deflection has to be microscopic... as for the debris the shield is super easy to drop and should be coming off for at least yearly oil changes anyway

Looked at mine this morning and there was a piece hanging off the rubber lip

Not sure how it’s happened and no other marks on the underside




Is this seal / lip only on EU cars

Should I be concerned?

Do we think this lip is in place to act as a gaurd or is it just a airflow modifier? Do we have a case against BMW for ignoring the lip? Can anyone provide me the part number

It's most likely for airflow. I have a similar hard rubber "deflector" on my Z06 and it's been said it's there primarily for airflow and helping to keep the vehicle stable at high speeds.

Looks like you scraped over a parking block or something similar.

Is the piece that ripped off the lip that small.piece next to your fob (for size comparison)?

Another reason why there is no "perfect fix" for this. Being this is not a new design to the G87, I am really curious how many cases have occurred like the OPs (again, nit making light of this but just being realistic as opposed to panicking cause of one report).

Yes. Seems a bit random

There's been at least 2 on this forum. And if spending $160 for a protective screen saves one from $46k in damage, what's the big deal? Window tint is unnecessary, but most of us do it. I've never seen anyone come on a forum and say "man what a waste of money on that window tint..."

I got under my wife's X3MC yesterday to check out her oil cooler. There are several areas with bent or damaged fins. Nobody makes a screen/grille yet, so I'm going to try to fabricate one myself. Cheap insurance.

Where is the other? If you are talking about the radiator, that is different and the two discussions should be separated.

Unfortunately, some are taking the guards as a piece of mind that they are safe (as Ronco said, set it and forget it), but those screens/guards are in no way a guarantee of safety/no damage. I can just imagine the first issue that arises to someone who had the screen installed, its really gonna be a shit show.

They’re not accepting the risk. They’re going to pass the cost onto all of us. Just you wait if this becomes a widespread issue.

The oil cooler underneath/behind the front lip has been present in the last ~8 years of M cars or more. If it was going to be widespread it would have been by now.

It happens occasionally, and BMW should do something about it. But if they were, they would have done so with the last gen of cars which already have a few threads like this one (albeit not as egregious as a drive home from the dealer in my limited searching)

It’s also happening to people with the ZTK package on the G42 M240i.

there is no guarantee. anything could happen. ive had a flying turkey strike my car and cause damage. but is it way better than nothing and serve to mitigate the chances of damage? absolutely. the other option is to be terrified to use the car, at which point i would just sell it. but to do nothing is to be foolish IMO

Wait, what? Are you fuggin' kidding me? They didn't have that on previous N5x engines. I can't believe they are doing this now with the B58. Well, if anything it just increases the odds this happens more and more and leads to a class action.

If a turkey hit OPs car I think he wouldn't be as flabbergasted at the results here.. the issue is that it's just a (relatively) small rock strike that he didn't even notice while driving until it was too late to do anything about.

People just want protection from something that should be a benign event destroying their engines. They shouldn't be expecting these aftermarket parts to suddenly make the oil cooler to be invulnerable.

I'm not concerned about the front radiator because lots of cars have pretty exposed front radiators. This underneath cooler is not as usual to have on cars and seems to be more vulnerable to damage just by being there, either from rock strikes, curbs, or parking stops.

Yep. Dude drove into a gravel parking lot (not uncommon out west) and smashed it. Even just a pulling out on the side of the road could do it, also not uncommon. Hell, I’ve seen paved parking lots that look like they just landed fresh from the Middle East.

You need to take into account that this only applies if they have the ZTK package. The majority of 2, 3 series do not.

The ZTK package is not a very common option. It’s the “high performance track package” that adds the underbody oil cooler, wider wheels, and some other performance related enhancements. I’ve only ever heard of it on factory ordered cars. Your average Susan getting a lease special M340i or X3 M40i isn’t going to pay $3,000 more for it. Hell, they can’t even bother to option summer tires on those cars. They all come with narrow Pirelli all-season run flats.
