Genuine Audi/VW Siemens VDO OEM part. The mechanical parts, motor, gear and valves are working, however the cover plate which contains the plug and electronics is faulty. This part was fully functional when removed for an intake clean. However, I opened up the cover plate to check condition and unfortunately I broke the electrical connections so had to buy another part. There were no signs of oil ingress and it was in excellent condition until my clumsy mistake. The sale is for a used and working butterfly valve, main body, motor and gears. The faulty cover plate will also be supplied. You will need to supply your own cover plate and gasket before fitting the part to your car.
