    Coolant top up

    Anyone topped up their coolant levels yet? Ive done about 7k on my polo tsi. Just checked the coolant level and found its a tad below the minimum level when cold. Manual states to add G12 Plus-Plus or G12 Plus. Should I head to my dealer for this? Or would somewhere like super cheap have it?

    Also engine has not chewed any oil so far.

    Got the same thing, no warnings yet and service is in a few weeks time so i gather its all good. Must be in all TSI's quite a thirsty bugger when it comes to heat reduction xD

    I have Nulon Red long life top-up Coolant, think its safe to use for the TSI? :/

    Dealer only. I doubt the retail shops would stock it.

    Nope.

    Refer to the owner's manual for further details.

    Your dealer might offer free top ups seeing as a) it's brand new and b)it's a sealed system so theoretically, it shouldn't have used any coolant because there isn't anywhere for it to go, which would mean it was over-looked in predelivery....

    guys i just rang the dealer. They told me its not necessary to top up until the warning light comes on. And in the case that it does they said its safe to top up with water. do I trust them? hmmm

    Hell no!!!!!! It says to NEVER top up with water in your owner's manual!!!!

    You introduce water, you dilute the glycol levels etc and can rust out your cooling system! I would leave it and monitor it over the next few months. If it keeps dropping, take it back under warranty.

    Mine dropped below the min once, and I topped it up with mineral aquifer water (not) and it's stayed put ever since. I recon its just on the initial run in. Checked it twice since, and it hast not moved.

    The small amount (less than 1/2L) can be topped up with demineralized/distilled water. The factory fill is strong enough to take it. Of course ideally you should use 50:50 mixture. Also remember never mix 2 different brands of coolant, use only G12+ or G12++ coolant as per your user manual. After you topped up with water, at your next service you need to tell your mechanic to measure the coolant concentration and adjust, if needed.

    Yeah, that makes sense Transporter I'm just going off what the owner's manual says and with having to fully strip out and clean the cooling system of a 4wd I owned due the flog before me topping up with water, I personally never endorse the use of water in any cooling system, but that's just me
