How to remove and refit the vacuum pump on Audi 100?

Removing the vacuum pump on engines with 4-cylinders requires the first step of prising out the covers, unscrewing the retaining nuts and removing the top cover. The vacuum pump is at the back of the left hand side of the cylinder block. Detach the vacuum hose at the very top of the pump by pulling off the retaining clip, loosen the retaining bolt and remove it to remove the pump retaining clamp. Removal of the vacuum pump in the cylinder block should be done and the sealing ring should be recovered and thrown away and a new sealing ring should be used during refitting. To refit, put the new sealing on the vacuum pump and put oil on to facilitate installation. Position the slot of the drive gear with the dog of the drive shaft, making sure that it is in correct position on the drive shaft (4-cylinder engines). Reinstall the retaining clamp and tighten the retaining bolt, and reconnect the vacuum hose, and fasten it with the retaining clip and before reattaching and tightening the top cover. In the 5-cylinder engines, the vacuum pump is attached on the left-hand side of the cylinder head. To remove the pump, remove the top cover, then disconnect the vacuum hose and unscrew the retaining nuts and washers and remove the pump and its pushrod. Refitting should be done with a new sealing ring discarded. Install the new sealing ring on the pump body and fit the pushrod and manoeuvre the pump into place making sure the pushrod is in place. Install the pump on its studs, re-attach the washers and retaining nuts and tighten them on. Lastly, reattach the vacuum hose and fit into the retaining clip.

How can the operation of the braking system vacuum pump be checked using a vacuum gauge on Audi A3?

Operation of the braking system vacuum pump is verifiable by means of a vacuum gauge after first removing the engine top cover and air filter housing with the vacuum pump being on the diesel model being in one with the fuel lift pump. Unhook the vacuum hose with the pump and hook the gauge with an appropriate length of hose on the pump union. Crank the engine and idle it, recording the vacuum formed by the pump, at least one minute later it should be at least about 500 mm Hg. When the vacuum is considerably lower then the pump might be defective and the opinion of an Audi dealer should be taken before it is condemned. Once more attach the vacuum hose since the vacuum pump cannot be overhauled because it is not available as discrete parts; in case of fault, the entire assembly of the pump needs to be replaced. Refitting will necessitate a new pump O-ring. Unscrew the retaining clip, unscrew the vacuum hose on the top of the pump and record the positions of the fuel supply and return hose before disconnection. Unscrew the two larger upper mounting bolts and the two smaller lower mounting bolts, remove the vacuum pump out of the cylinder head recovering the O-ring seals to disgrace and get new ones to replace them. Install the new O-ring seals on the vacuum pump and smear it with oil so that it can fit into position, then position the vacuum pump into position by making sure that the slot on the pump drive gear fits into the slot of the pump driveshaft. Install pump retaining bolts and tighten them to the required torque, re-connect fuel hose, re-connect vacuum hose and attach it with the retaining clip, and lastly, install air filter housing and engine cover.
