Decoding Volkswagen Coolant Families: From G12 to G13Volkswagen has evolved its coolants over the decades. Here’s the lineup every owner needs to know. Classic and Reliable: G12 CoolantThe original long-life red/pink coolant (OAT technology). Nitrate-free, phosphate-free, and silicate-free, G12 was used by the auto manufacturer from the late ’90s to mid-2000s. G12 (original red) G12+ (improved red/pink) G12++ (even longer life) G12 EVO (latest violet-ready evolution) Ideal for the MK4 Golf, the Beetle, and the early Passat. The Modern Eco-Warrior: G13 CoolantIntroduced around 2008, G13 swaps some glycol for glycerin (a veggie-derived byproduct), making it more environmentally friendly while still delivering 150,000-mile protection. Violet or purple color Fully compatible when mixing with G12+, G12++, or G12 EVO Slightly different corrosion package, even better for newer aluminum blocks Recommended for every Volkswagen from model year 2008 onward (Atlas, Tiguan, newer Golf/Jetta, etc.). The Universal Champions: G12+, G12++, and G12 EVOThese are the “safe for almost anything” options. Silicate-free, backward-compatible with old G11/G12, and forward-compatible with G13. Use them to top off almost any Volkswagen vehicle without drama. Built to add long-term rust, frost, and overheating protection. REAL-WORLD EXAMPLE: A correctly matched G12++ or G13 mix prevents radiator rust, resists freeze damage in winter, and helps the cooling system shed excess heat.

Don’t Ignore It!When the red thermometer or “coolant low” icon lights up on your dashboard, pull over safely, shut off the engine, and let it cool for at least 30 minutes before popping the hood. Hot, pressurised coolant can cause severe burns. Mixing Coolants and Smart Upgrade TipsYes, G13 plays nicely with G12+, G12++, and G12 EVO in a pinch, but always top off with the exact specification for best results. The following color guide is helpful but isn’t foolproof: G11 – blue (ancient, avoid) G12/G12+ – red or pink G12++/G13 – violet/purple Never gamble with off-brand “fits all” coolants; they often contain silicates or phosphates that attack Volkswagen seals and sensors. Stick to genuine Volkswagen G13, G12++, or G12 EVO.

RacingLine also have some upgrade parts if you still want more stiffness (ooo, err) after doing the 'bushes': https://www.racingline.com/mqb-underbody-brace https://www.racingline.com/mqb-subframe-brace

Horses for Courses really, everyone has their own idea as to what they would like to achieve. My advice would be to look into RacingLine and Revo authorised tuners in your area and take it from there.

Is it true that the 4.5 vRS has real pops and bangs from the exhaust in 'Sport' mode (not just the internal actuator)?

Sorry to state the obvious, but it may possibly need a re-gas?

I'm hoping to be there with my Octavia 230. Looking forward to seeing the Superb 280 @gav_is_con

Why are you looking to revert to OEM? Are you not happy with the performance, or is there an issue?

As mentioned already, the Skoda/ VW SatNav is nowhere as good as a Smartphone; I have both, and have only been using Apple Maps for years (via CarPlay)

I purchased a Service Book which I also get stamped at every interval, for a tangible record that I can keep.

The question remains: does your car have driving modes?

I started my Octy with a warning message and realised the coolant had drained completely via the coolant outlet, which perishes due to it's proximity to the turbo and therefore the heat produced. This was replaced, and all good from there onwards.

What car is this, Octavia 3 or 3.5?

How are Driving Modes and Traction Control currently controlled on your car?

Sounds great, I'd love to see it if possible. PS regarding your order from Kopacek; I heard that they stopped delivering to the UK after Brexit?

Do you have a link please? Also, any chance of a pic of how they look? Thanks
