Coolant Warning On Dis Morning Cold Starts?

[Omy193]

Hi Guys,

I Have a 55 reg Audi A3 TDi S Line DSG

For the past few mornings when i start the car up (cold start) the coolant warning pops up on the DIS and beeps for a couple of minutes and then just goes off?

Doesn't come on again until the next morning when starting cold.

Is it just a sensor problem or something minor?

Thanks in advance guys!

Stupid question but have you checked the level?
or do you park it on a hill?

could be a faulty sensor or your mixture isn't strong enough.

mine used to do this a lot but seems to have stopped since I added neat Coolant.

Hi

Sorry should have mentioned in last post, coolant level is fine. Just a tad below max.

And yes car is parked on my drive way overnight which is level ground.

Will try a better mixture, thanks!

If it goes off after a while i wouldn't worry too much! if it stays on PANIC!!!

It will be the bottle contacts you can see inside the bottle. Either change the bottle or try and clean the fine layer of ***** off the prongs.

Yeah just use a long screwdriver when cold to scrape the crud off the sensor inside the bottle.

Scratching the probes with a screwdriver cured this for me too.
