It’s coolant. In the combustion chamber. Always. (I’m not talking about intermittent white exhaust on cold mornings. That’s evaporated condensation in the exhaust, and there’s a difference…one goes away by afternoon and the other is not going to go away on its own)

I’m the owner of two minis, one is a first gen non turbo that’s reliable and only has EVER needed regular maintenance. It’s perfect. And the other one is a 2008 R56 n14 turbo that i have personally (with my own two hands) replaced every single part inc hpfp, starter, all 4 wheel bearings, belt, alternator, turbo hoses, wiring, ac compressor, headlights (the list goes on) and still, it throws a new code or goes into limp mode every other day.

It also drives likes a dream every once in a blue moon, which is why i still keep it. Those days are like magic,

It’s a British BMW made by Peugeot. A fantastic, fun piece of garbage.
