So i get up on my day off to find that ive got a puddle of coolant under the car? After jacking up the car and doing a quick search i discover that the water line on the turbo is leaking on the banjo bolt?? Is this a common fault with the standard lines? Ive got braided ones to go on but thats when i have a bit more time. I also noticed that i was missing a bolt on the turbo elbow, im thinking this could have caused some vibration which in turn loosened the banjo bolt.
