Recently noticed coolant on the garage floor. Took it in to my trusted indy for evaluation....they diagnosed leaks in both turbos...the driver side more so. $4500 for each turbo (part only) plus labor, etc, etc, to remove the engine to get to everything. Total damage somewhere in the $13-15K range. What a lovely Christmas present! Anyone else had issues with these watercooled turbos leaking coolant?

Might be time to give Speeddriven a call.

yes i have seen V12TT leak / loose coolant from the turbo

This is a newer model, any warranty? In any event isn't this hopefully a plumbing fix? New turbos seem like worst case scenario, i'd get a second opinion.

Since you need new turbos are there any vendors that sell upgraded turbos?

I feel for you man. Uncle had the exact same issue on his Porsche Turbo, total damage was slightly more than what you're looking at.

Why/how would turbos leak coolant? You would think it's just the banjo connections or crush washers? That must mean the turbo bodies are cracked? I've never heard of that.....

I agree. My Indy lets me check out the car when it's on the lift. I would want to see the leak. Can't just start throwing parts at it...that's what going to the dealer is for! Make sure he's seen this engine before; experience is everything.

I got a look at the leaking turbos. The turbos have what looks like a freeze plug on the housing. The leak is coming out of these "freeze plugs". Apparently Mercedes Benz does not offer the freeze plug as a replacement part....not that you could not fabricate one. Still would have to pull the motor to replace them. What a tool job.

my buddy has a '07 W221 S600 had the same thing happen...under warranty.

Yep, happened to me but was just an O-ring where the coolant flows int the turbo. But, required some massive labor......all under warranty of course. Your turbos aren't bad......thats ridiculous.

It's stories like this that people who even consider owning one of these cars without a warranty need to read.

This is what my turbo water seals looked like after 10 years. The top ones (coolant outlets) were heavily perished, but still weren't leaking. I replaced them with the new red ones. Like divertor valve diaphragms, this isn't something you would do out of choice.
