This pump came well packaged , and is a brand new one, did,nt have a scratch on it any where,it fitted straight on to my 300tdi engine, so far it's done about 250 miles and it is working fine, a new gasket supplied with it would be nice but for the price , (which was about half of what I was expecting to pay ) I can,t complain, the build quality actually seems better than the original one, and is certainly all machined correctly, as I said it fits and works perfectly, these pumps in general are not noted for there longevity,however I got exactly 160000 miles from my old one from new , which I consider acceptable, I think this new one looks quite capable of doing the same, If you need a new 300tdi vacuum pump for the money and speed of delivery ,this is the one.
The vacuum pumb although not a wabco was identical and fitted my discovery 1 as a direct replacement. The vacuum pressure has made a big difference to the braking assistance. Highly recommended.
