Coolant

[xavpiq]

The dealer topped it up to the max 3 weeks ago and I have done 450 miles since and it is going back down so must be internal.I phoned dealer today and it is booked in for Monday to do a pressure test I think.23643574-957F-4535-BA50-357E4293D196.jpeg

I checked mine and it is exactly as yours. 7000 km (4350 miles) in 9 months, never topped up.
Should I worry ?

I only noticed the coolant had dropped whilst topping up windscreen wash and didn’t have any warnings.I would see your dealer and get him to check your coolant system as it should be on the maximum level as it is a sealed unit so shouldn’t evaporate

It wont evaporate - but no system is totally water tight or hermetically sealed.
It cant be - there are too many joints and gaskets to consider.

Bear in mind the temperature at which the system is filled , and the temperature it is checked.
Coolant properties change with temperature

if the system is going down quickly - then worry.

Don't forget , as an owner/driver , you periodically check things on your car because they are not perfect and nothing lasts forever.
We have become spoilt by modern manufacturing and reliability , but remember the old days when checks were weekly or daily !

I noticed today that my coolant went below the minimum. It is 9 months old and has done 14 000 km.

We have any news from the problem with the decrease of coolant?

I own a QQ e-power and i'm a little alarmed because i have two coolant reservoirs to check, one for the engine and the other for the inverter.

Had lots of cars in with similar problems the cap must be on tight that's the first check

Well my J12 needed a new engine at 4.5k miles due to coolant leaking into the engine. Just got it back and seems okay yet but i've only done about 200 miles since picking it up last week or so.

After refill at dealer it is dropping again. I did only 500 km.

NIV, that seems very worrying.
Contact the dealer again. If it's not an external leak of the coolant system, check for internal one ( I'm afraid of head gasket ? )
