I wonder if these leaks are the reason why the new S58 motor puts the air/liquid cooler vertical and on the side of the motor and not the top like on the S55. By doing that, it greatly reduces the chances straight liquid going into the intake manifold. With the S58, the liquid would be more like a mist.

Sounds like the S55 has a few more potential issues than the N55.

A case of mo ponies mo problems...

For sure but it's still a rare problem. But my OCD will cost me an upgraded aftermarket charge-cooler and an upgraded front oil cooler guard shortly after taking delivery

Agreed, my OCD is high to the point where the available oil cooler skid plates still leave it vulnerable to smaller objects (stones, wires etc).

Will the aftermarket charge cooler void warranty?

Replace „after taking delivery" with „after the warranty expired"

Ride her HARD during the warranty period!

Regarding your (our) OCD -> don't forget about the spun crank hub!

Chances seem to be high that if at all, it (SCH) will happen sooner than later. And as long as all is covered by warranty mucho bueno... If the crank hub does not slip during the warranty period chances are very high it will never happen at all.

In Switzerland, of course yes...

Another reason not to modify during warranty period

Agreed.

In Canada I suspect it will open the door to warranty rejection as well...

It will if it's found to be the cause of the problem. But I'm sure when the turbos need eventual servicing they will blame it on the intercooler. But I would rather pay for servicing in 7 years time versus risking coolant leak into my intake manifold or the fear of it happening at any moment at any mileage. I'm hoping somebody will open up their damaged oem intercooler soon so we can get to the bottom of what's causing the problem before i upgrade

The issues with the S55 are convincing me to keep the 2018 for now...

I would do the same but I've decided to sell my left kidney so I can have both cars

I'm thinking the same way but really can't justify the M2C given what I'll use it for...

I don't understand the rationale in changing the cooler during warranty.

If it leaks BMW will replace it with a new one. If the leak causes engine failure then BMW will either rebuild it or give you a new engine replacement.

All the aftermarket cooler will do is to lighten up your wallet (during warranty period) and give BMW a chance to deny your engine warranty if the aftermarket cooler s somehow faulty and caused engine issues.

I agree with all you've said but I suspect the part about getting a rebuilt engine may explain the rationale for some.

Reviving an old thread here. It seems that I'm experiencing the same failure as mentioned in this thread.

Took the car to the track this past weekend and received the drivetrain malfunction error after a few hot laps. Immediately noticed a lost of power (not full limp mode), mainly a lack of boost. Pitted, turned off the car and waited a little, turned the car back on and the error was gone. Went back out on the track and the error came back.

I ended up reading the code and it was indeed P10B0. I checked the coolant levels, the main reservoir was fine, the expansion reservoir or whatever it's called (smaller one, top of the charge cooler) was low. I checked for leaks but couldn't find anything. I topped it off with some distilled water, cleared the code and took the car out again on the next session. Error came back and so I called it a day. Guessing that the leak is internal. Code has since been gone and I was able to drive it back home.

Talked to an indy near me and he immediately suggested it was an internal leak and suggested an aftermarket upgrade. Car is a 2020 with only ~10k miles. I have an appointment with the dealer this Thursday for them to take a look. Since the car is under warranty, I'd rather have the dealer replace it first, than plan on upgrading it after warranty is out. Will keep ya'll posted after I bring the car in.

Curious, mine has 30,000km since 2000km it has been stage3 and at the moment 0 problems with 610hp.
It would be nice to know why it happens.

Probably manufacturing defect for some, thermal cycling for others.

I've noticed many get topped off at the dealership to a point much above max… that might be a reason too

[okla_m2c]

Update: dealership confirmed that there is a leak and the TMIC will need to be replaced. Unfortunately, they don't have one in stock and it's going to take several weeks for them to source.

Per the tech, it seems the leak only occurs under heavy load / when hot. They're ordering the part and I'll bring the car back in when they have it. I plan on upgrading to aftermarket but might as well use the warranty while I still have it. They gave me a whole jug of coolant meanwhile.

Fingers crossed it comes in time before my track event in a few weeks.

Upgrade it to the mishimoto piece after you get a stock one

If you're planning on keeping the car for the long run, I would suggest order an aftermarket (Mishimoto is a good choice) and maybe sell the new one dealer installs. Too many of these seems to fail and you never know how much it will leak… massive leaks do happen and it would be a pain to deal with that

Do you think I'd be okay for now with just buying the Mishimoto TMIC rather than the full-on kit that includes heat exchanger, charge pipes, etc.?

Not opposed to buying those other things later, just really no need for it now, especially with everything still under warranty.

Maybe I could just buy now and install.. Then remove/replace with stock when I bring it in for normal servicing. Just afraid the dealer might say something about the warranty.
