Ok so went to close my drive up tonight and seen all these black specs on the floor, touched it and felt a bit greasy. Upon looking under my car I can see it's wet under the drivers side front. Iv not long had new timing belt and water pump changed. But noticed over the past month when turning hard left or right it clunks under the drivers side. I though it was my cv joint (just what my boss suggested) but now iv seen the leak I'm pretty concerned. Its a mk7 ford fiesta 1.4 petrol. Might I just add this is my baby but it's started costing so much. Could anyone help in telling me 1. Is it worth fixing? 2. Expected cost? And 3. What is leaking. Pictures added.
