Bmw 118i low coolant warning

[Fausto]

Hey guys,

Back with another question/problem

Today in the morning I got a warning for low coolant (pic attached). I then stopped the engine, started it again and the message disappeared. I also had a look at the engine coolant level, and it does seem low (pic also attached).

There is no sign of leakage around the engine, or the tubes and neither on the ground, so I'm not sure why the level is so low or if this is even a normal occurrence and the coolant needs to be re-filled once every few years.

My car is a 118i from 2017 with ±138.000 km. Recently (±2 months ago) I did a service where the distribution cap was changed because oil was leaking from a seal around the distribution cover and BMW service has not mentioned any coolant leakage back then.

Could it be that some coolant was lost in the process while they changed this piece? The service DID mention some "antigel" (I think translated it means anti freeze / coolant) change that was not needed, and the total price paid was less than the original quote.

This is what I meant by distribution cap (just to make sure we're talking about the same thing as I translated it word-by-word from a different language).

Update: I went to a mechanics store and bought this type of coolant, the guy said it's for all vehicles including BMW and I can top-off safely, do you guys think it's OK?
