The car is an E Class (W213) with an OM654 2 litre diesel engine. In operation the temperature indicator rises steadily to 90C and stays there without any noticeable fluctuation. The other day I noticed signs of coolant loss from the cap of the coolant expansion vessel; there were salts stains around the rim of the vessel and pink coolant filled a dimple in the bracket that supports the vessel. On removing the cap the vessel was quite empty and took one whole litre to bring the level up to the indicator 'tongue'. Apart from a faulty cap is there anything else that I should consider.
