Bummer sorry to hear ... some early 14s had a bad batch of water pumps etc etc
No extended warranty huh?
Well .. I bought it in 2014 .. it had 3,000 miles on it "used" and was "certified" by the dealership .. so instead of a 3 year warranty, it was four. It was a pretty good deal at the time.

I suppose "extended warranties" get a bad rap .. seems like a dollar grab by the dealership right at the end of your car buying experience and you're not ready to do that math.

Sounds familiar. My waterpump failed as soon as warranty expired. Of course I paid for it as it died 2 weeks after week warranty. 2014 CLA with 27000+ miles at that time. Now I have my own MB mechanic I won't be going back to the dealers for repairs. I feel your pain.

I don't know why anyone would go to the dealer for work on their car after the warranty expires. I certainly won't.

My dealership was definitive about courtesy out-of-warranty repairs: It's not going to happen. Once it ends, it ends.

Sounds like there's a different answer?

What were yall’s symptoms of the failed water pump? Any precursors or just overheated?

My car always ran pretty well. On the day it failed, The car ran fine.

HOWEVER .. thinking back, a few times -- but months / year ago -- I saw the temp gauge go super high then snap back down. As I said, it was months and months ago .. and I only witnessed it twice. It's entirely possible it did that dozens of times and I never noticed it, as it only happened for 1-2 seconds and unless you are staring at your dash, you'd miss it. *Maybe* it was happening prior to the pump failure.

This is where obd data logs can help ... plot the temp data and any oddities will show ... like those temp spikes

My temperature gauges were going way above the normal range (into the red) and not coming down. I pulled over and when I turned on the heater to try and cool off the car, it blew out cool air. That’s when I called roadside assistance lol.

No precursor signs. Drove everyday without any unusual behavior then one morning it just overheated as I exited the highway towards work.

when he said something was stuck open I wonder if that was the thermostat. And reference the fumes, anti-freeze has that sickening sweet smell to it. Did it say on the repair order if they replaced the water pump or thermostat?
Water pump is pain to change. There is a lever which opens and closes the pump. that gets stuck.

So what symptoms showed? Temp jump?
Any odd noises?
There were no symptoms, no warnings, no odd noises. The temp' jumped as we were getting onto the highway. Immediately we pulled over and had the car towed to the dealership.

Well, on my way to a Dr. appointment 3 weeks ago the center dash where the spedo shows, "Engine overheating, pull over and turn off engine immediately." You guessed it, Water pump. I knew there was a very small leak somewhere, but could never find it. I assumed it was some porous casting somewhere and my dealer is 50 miles away. The car had 37,800 miles on it. 3 months out of warranty. Well, being fairly experienced at repairs I tackled the job. I am sure that Mercedes wouldn't totally approve,l but it is back together and working well for the last two weeks. The job is horrific! At times I even thought of pulling the engine ( I have an engine lift). I'm not sure a private shop would tackle the job and if I was one I would turn it down. The underside of the pump has a valve, actuated by vacuum, where there was a leak around the piston that finally froze it in the closed position resulting in instant engine overheating. You can see that it is a common failure point by searching the net. There is also a video of a mechanic putting one in. I avoided some disassembly with a work-around or two.

Wow ... glad you managed to sort it out
You happen to grab some posterity pix?
I presume this is the unit driven by the belt
Would love to hear about your workarounds as i am sure more of us are gonna walk in your shoes sooner or later
Your thermostat still ok?
