just a reminder - if your coolant reservoir is empty, don't automatically assume it's the charge cooler leaking into the intake manifold. take a minute and closely inspect your heat exchanger.
mine emptied out a couple weeks back and just installed new chargepipes, IC, spark plugs, and j pipe this weekend thinking my IC took a dump. ended up being a nasty nail that took out my heat exchanger. i inspected my HE, but didn't notice any damage prior to ordering parts. apparently i just didn't look hard enough. happy i changed the CPs and IC already since they're known weak links on the F8x. |

Just had mine done under warranty, the total was $1,716 for parts and labor. Parts were a little over $900. If BMW doesn't cover it for you, time to get an aftermarket one. |

If all they did was replace the cooler and then re-fill the system, the clear answer for anyone out of warranty is to go to an indy shop. Or just DIY since there is a lot of DIY info on the interweb, including videos, where people have replaced the cooler. Then follow it up with an internal chemical cleaning with a product like CRC GDI Intake Valve & Turbo Cleaner to remove any residual, dried coolant in the intake tract downstream of the cooler.

I posted this in general forum too. Can anyone help?
So, I was walking up to my car one morning and noticed a tiny green droplet of coolant on my exhaust tip. On the inner lip of MPE. I keep the tips very clean so I do notice those things. I started the car a few times, took it on a few drives, and I always touch the intercooler when idling because it's pretty cool that it stays cold. That was until the last drive. I touched the intercooler and it didn't feel ice cold as it usually does. Kinda warm. I checked my intercooler fluid reservoir tank and it was low. I had to add about 2 full cups of coolant/distilled water mix to get it to full about 28-32 oz I'd say. I took the car into the BMW dealer I go to a few days before my warranty expired. Talked to my SA. The dealer did a pressure test overnight and found no leaks. They are saying it's fine and ready to pickup? : I would hate to take it now out of warranty and have it leak again and then have to pay an out of pocket expense. The thing I don't get is, I had to add coolant into the reservoir. I thought It was sealed. It should never consume fluid, unless there is a leak. How can it be fine? I'm not sure if it leaks under vacuum or under boost. What should I do next? 1. Pickup my car, the pressure test is thorough. Maybe, I was mistaken on how much fluid there was to begin with when I bought the car. 2. Ask them to remove the intake manifold to physically check for leaks. Doubt they will just do that, especially during COVID-19 set backs. Especially if the pressure test came out saying there are no leaks. 3. Call BMW North America and make a stink? I probably wont be able to go back to the same dealer again. They will probably hate me. 4. ????

papasmurf_m3 make sure you have the issue noted on the record and a follow up email stating that you have experienced multiple times a loss of fluid. Just a nice email to cover your ass.

I got the error code that the intercooler reservoir was dry. I filled it and drove around for the day. Checked it the next day and it was empty again. There were no drips under the car and no signs of coolant anywhere in the engine bay. I Googled the issue and came across this thread - and PANICKED.
Today I pulled the intercooler off to inspect it and it was dry as a bone with no signs of coolant anywhere. WHEW! So I filled it again and just let the car run in my garage. Turns out it was a leak in the front radiator from some rock damage. You might be saying I should have done this in the beginning but I was too paranoid about getting coolant in the motor. Moral of the story is don't immediately order a new intercooler (which I almost did yesterday) until you diagnose the issue.

No because you can look through the grilles and see almost the entire front radiator. I will have to remove it to replace the radiator though. But its pretty easy.

Thanks for the update. Glad you identified the issue. However, just curious...if the radiator had a leak, the coolant would have to have gone somewhere and why wouldn't it have then appeared on the ground in the vicinity of the radiator?

My post definitely begged that question. I've only owned the car a month and barely driven it due to the quarantine. I didn't even realize the car had the issue when I got it because there are no warning lights on the dash when this happens. So when I filled the reservoir and drove it around, it completely drained before I got back to the house. And it only leaks when it gets up to operating temperature, not when its cold (so the hole is pretty small). So even in my garage it took a while before it started to drip.

Any updates on the reliability of the replacement units we've received? I got mine around 23k miles...should I expect one more freebie before warranty is out?

I had my charge cooler replaced over a year ago.
I just started noticing this white residue on a section at the seam. Anyone else seeing something similar and had their charge cooler expansion tank replaced as well? Thanks.

Probably starting to leak or it’s residue from spilled coolant possibly.

Yup, mine looked like that and took it into the dealer last week. They found it was leaking and replaced it.
