Hi guys, I have a audi a6 3 litre quattro tdi. Seem to have a split pipe leaking coolant/fluid. Been identified but its at the back of the engine bay and seems to be where a rubber pipe connects to a metal pipe which then follows towards the gearbox under the dash. Wondering if anyone can help as to what pipe it maybe so I can order it rather than a garage completely stripping it all out. Thanks
