Hi,

We recently had coolant leaking, but that's been fixed. However we still get the warning message and the red triangle. Coolant level is fine. I assume it's a sensor/float problem. Here's the question, is there any way for the coolant level to look fine but coolant not going through relevant hoses? I.e. a blockage somewhere.

Thanks

Someone could help you better if they knew what vehicle you are talking about.

.
the float inside the coolant bottle can sometimes fail, float absorbs the coolant requiring the entire thing to be changed

That’s if it’s a D3 or 4, will search for the part numbers in case the float is now available on its own

Hope that helps

Part number for a new expansion bottle , complete with float LR020367, believe many either get the MEYLE or BEHR seeing the genuine ones are around £116 instead of £60 for the MEYLE

Welcome to the forum.
Maybe you'd like to go to the "introduce yourself" bit and do just that?

If you link the two terminals on the sensor plug, does the warning disappear? if not, it's a wiring issue, if it does, its a faulty sensor / fitment issue.
