I got a Coolant low pop up the other day when i first started the car. I was taking my c450 in for its recall and had the dealer also check this out. The service writer and the receipt said the system was topped off and leaked check with no problems found.

Now the crux of the problem is I just had my 10k service only 5k miles ago and that was performed at a different dealer that this service call.

So one of two things has happened. Either the dealer didn't do the 10k check properly or I have a leak.

Since it was just checked today I would think that the dealer that i took it to for the 10k service is at fault.

Any input would be great.

Thanks

Frankly - I would not worry about "leakage" unless you or the technician spot some fluid. Frankly -

The the new gen Mercedes Coolant Level Sensor systems are quite/quite "sensitive" - meaning 2-3 oz either way can cause a alert under/over.

any significant temperature changes lately? Change in altitude? I wouldn’t worry about it unless the light comes on again or you notice wet spots under the car.

I had a 2017 C300 loaner that overheated on me within 5 minutes of leaving the dealer. They actually put on my file at my dealer 'No CLA loaners or car #4' haha

Anyway, I think it had a leak.
