Hi all - took my car out for a drive last night - hadn't been driven much in the last month or so. All was fine until the way home, when I turned onto a residential street and heard a very strange noise from the driver's rear - almost sounded like a flat tire, but was burbling at low speed like an exhaust issue. No loss of power, no loss of boost, no lights - noise would come and go and was not present at normal speeds, just occasionally at low speeds (less than 15 mph). I couldn't get it to reliably reproduce before shutting it down for the night.
This morning there is an orange fluid on the ground, and I can barely see under the car to find where the drip is coming from. See pics attached - the fluid is slightly oily, not a huge amount but obviously has been dripping overnight. I have not started the car at all today since this kind of stuff freaks me out. Any ideas as to the culprit - what fluid and where the leak might originate? I wonder if the noise was from the fluid hitting the hot exhaust and burbling.
I figure it's coolant coming from somewhere underneath the tank - can't tell if the tank has a split, a hose has failed, or if maybe a fitting is giving out. Power steering leak would be towards the front, wouldn't it?
Sorry for the pics - the car is in a small one car garage and I don't want to start it if it could worsen the issue.
