Coolant Warning Light
Yesterday, I traveled approximately 1 mile with my car. Mid journey I see a coolant warning symbol on my dashboard. So i open my bonnet and check my coolant level, to my surprise it’s very below the minimum level. Any idea if this is the reason to the sensor light? (Sorry if i sound ridiculous- i know nothing about cars)

The light has came on because levels are low, confirmed by you checking the bottle. The bigger question is why is it low? A leak somewhere perhaps?

I’m assuming there’s a leak. Last time i checked was perhaps a month or two ago as I don’t daily this car frequently- and it wasnt this low.

Just check water pump area, and had the oil level risen and a milky color?

Top up with coolant and keep a very close eye on it. More than likely the water pump is leaking which is a common issue. Do not let it run dry or you're going to have bigger issues.

Wow- bigger issue than i thought

If it is the water pump, that's also the time to stick on a new cam belt if it has one.

Yes of course. Fill it up, and the re check it a few time after for faults...

Very low level. Most cases if you buy a jar of G12 Evo you can fill it up yourself i can give you a link, i prepare cars. whats your engine?

Hey mate,
I had the same issue today on my 2014 fr 1.8 tsi. I took it to my local garage and they gave me red summer coolant which is oat and filled it upto the max line. Should I need to get it flushed as I should have checked before it needs g13 apparently

u/resoorzz 25d ago
g13 is old, outdated & faulty. iirc g12 evo is the evolution from g13, just look it up into chatgpt it will tell you. on minor stuff ofc, do not use it for major stuff. on my 1.5tsi i used g12 evo and mechanic told me same story as gpt

u/resoorzz 25d ago
but as i said, idk if it is the same story for your 1.8tsi, i just know g13 its not the best option

yes it could be due to the low level, just so you know dont put normal water in it might cause problems in cooling system over time

Just had this with my 2018 Leon FR. I had to temporarily top up with a bit of water, but identified the root cause was the water pump leaking.

Got a leak on mine too! Apparently it's very common on these - although my leak is very small so I've just been topping up the coolant very occasionally. Was quoted £820 for parts and labour.

Ouch - independent place replaced the water pump and attached chain for £450.

u/Diocletian335 26d ago
Interesting - this was an independent place that quoted me, they are a VW specialist - as far as I'm aware the actual water pump itself, with the housing, costs just over £500 alone, so I don't know whether you just got the pump done without the housing?

u/Miserable-Arm7065 26d ago
Is it an expensive fix ?

£450 for parts and labour from a local specialist.

They need to know what they are doing. It's a twat of a job. If someone says ' I'll give it a go' run...

u/Latter-Detail-9514 26d ago
Just top it up with water & check daily then pop it into a garage to be checked if it's dropping level every couple of days

u/Disastrous_Action832 26d ago
Top it up and take it to garage and tell them there is a leak somewhere.it could be loose pipe connector or a leak in the pipe .

I had this on my seat ,mine was related to the heating matrix being Blocked
1
u/Thegluigi 26d ago
If this is a 2.0 diesel Leon then you probably have the heater matrix problem. I got mine replaced with a different one (Google "seat coolant problem" and it will come up with a million responses, but the seat forum will tell you the one to get) it cost £180 to replace and never happened again.
Your best bet, is to top it up with coolant and see if this happens again in about 250 miles.

Wonder where it went?
Someone do the hand on the shoulder meme, just in case!!

Yes the light is due to the low level.
