Water pump? HELP Hi, I have a 2008 3.0tdi cab with 32k on the clock, car runs very well but in the last week or so I've done about 1000 miles and the coolant dropped well below the min, needed about 1.5ltrs to fill it up. No obvious leaks or smoke and oil looks fine. I've done a bit of googling and am starting to wonder if it is a water pump issue. Can anyone confirm if this model is prone to water pump failure and if so how do I go about checking, I cant even see where the water pump is lcated to look for dampness! PS just bought a caravan - I know what you are thinking but it's been mapped so I won't be holding anyone up!-and am heading off for a few days next week so dont want to risk a break down then!
