I have a 2025 Octavia VRS with 23k miles, it’s been using coolant, I wouldn’t expect this from a car of this age, there’s no wet spots on or under the engine.

There has been an intermittent low level coming in for low coolant, level was topped up with manufacturer coolant today. I can’t get an appointment with a dealer or my lease company garage for two weeks.

Am I worrying about it too much or is this a common issue for the VAG 2.0tsi engine

My 1.8 had a similar problem. I asked my local dealer (Fred Rees in Haverfordwest) to sort it whilst it was in for a scheduled service. When I got the car back they said "Yes, you have a coolant leak . . No, that wasn't on the schedule so we didn't sort it".

A little two man garage around the corner knew what the problem was immediately. The water pump gasket was leaking. They fixed it for me.

I have a 23 plate VRS and recently had to add half a litre of coolant. No sign of fluid anywhere. Check everyday now and level hasn’t moved. Concerned im out of warranty end of October🤷‍♂️.

Suggestion to OP, contact Skoda Assist and they will come to you and if any issue found will take to garage who im told have a week to repair.
