I've been dealing with a slow coolant leak on my Countryman for about six weeks now and it's wearing me down. I top it up, a week later it's low again, but there's no puddle under the car and the temperature gauge stays normal so nobody seems to take it seriously. The first garage said it was probably the cap, replaced it, leak continued. The second one pressure tested it, found nothing, and told me to keep an eye on it, which is basically them washing their hands of it. I've read it could be the water pump, the thermostat housing or even a head gasket starting to go, and honestly the not knowing is worse than the problem. Someone pointed me toward a trusted MINI Cooper service gara ge in Musaffah and said they'd sorted a similar mystery leak on a Clubman, so I'm tempted to give them a go.
