Bonsoir à tous j'ai le même défaut que vous sur ma C300 de 2018.
au compteur j'ai eu un message qui me dit que la boîte à vitesse a surchauffer.

j'ai changer les 2 pompes auxiliaire mais le défaut survient par moment.
Pensez-vous que sa vien de la purge ?
J'envoie le défaut en photo.

merci de votre aide.

Hello. I have the same problem after installing a new cooler. Does anyone know how to bleed it with xentry? it was filled with negative pressure

Hi there: I have these 3 codes now too after mechanic changing seeping coolant pipe. The pdf that was posted has high temp fault codes shown.. I have the 3 include the low temp circuit as person posted as part of initial query. I am a little confused by the string of replies: Was this finally fixed by vacuum bleeding the coolant?
