Coolant residue nearby turbo?

[parky1215]

While workin under the car today, I noticed what looks like dry coolant on one of the turbos. What do you guys think it is and how should clean up this mess?

I recently had top mount intercooler leak so it was feeding coolant to the engine. not sure if this has anything to do with this...

First step to check I guess is making sure the bolt securing that pipe didn't loosen up, make sure it's tight.

It looks a bit worse than it actually is, but either a loose bolt or failed o-ring.

Thanks for the suggestion!
I will clean up the mess a bit then check the bolt later this week.
If it is not bolt problem, I guess I will make appointment with EAS to check it out.

Did you ever solve this issue? Was it the bolt or the o-ring that had failed? I have a similar issue on mine and have purchased a new bolt/o-ring. Going to tackle the job myself.

Mines looked like that and I had to get the turbo coolant lines replaced for both turbos. About 6k at the stealership. Take god for extended warranty!

Did they tell you why the lines had to be replaced? Based on my reading, it's usually the o-ring that fails.

I think since they had it out plus it was under warranty they just replace everything. The lines did look like sh!t when I saw the photos.

Fair call! I haven't found many threads on this issue so musn't be too common or not enough for people to talk about.

My car is very low mileage (47k Kms) so surprised this has happened; unless some previous exhaust work (downpipes) has caused the issue, who knows.

Mines had 68k miles

I'll report back on how I go with the job, hopefully it's just the o-ring and not the actual line itself!

Any updates? I notice the same coolant leak when I was doing an oil change today.

Haven't addressed it yet. Just in the process of collecting parts, I'll let you know when it's done but seems to be a more common issue on other water cooled turbos on the BMW platform (o-ring fails) but less common on the F80s..

Everything works okey?

I finally got around to completing this on my car; updated my original post:
