You can put a plug in the vacuum line or put a cap over the port at the other end of the line. Ask for Vacuum Caps. Note: The air injection system on my car is much more than just the smog pump. I think you should try to understand the operation of the system before you try to remove.

Yes, it will probably be necessary to fix the problem in order to pass emissions requirements. The secondary air injection pump on the Beetle is apparently used to accelerate the transition from cold start to hot catalytic converter operation. Without this system, it will take longer for the catalytic converter to reach operating temperature. The ...

A few comments in addition to David's answer: You can be creative with how the vacuum hose is closed off Something as simple as a bulldog clip will do - the purpose is to seal off one end. Another more permanent solution would be to remove the hose and weld the nipple shut Don't forget the other holes resulting from a smog pump delete There are other ...

The secondary air injection system is part of the emissions control system. Under certain operating conditions, the secondary air pump runs to bring fresh air into the exhaust system. It supports the proper function of the catalytic converter by making sure there's enough oxygen in the exhaust gas. Will it hurt anything to drive the car? It could ...

You may want to think about getting it fixed vs. ignoring it. In this case, the problem is more than likely in the solenoid which directs air from the pump to the cat. Depending on the exact malfunction, you could be seeing decreased fuel mileage and also damaging your catalytic convertor. There are some reasonable tests which were written up on OBD-Codes....

Should I just remove the pipes going into the manifold and just tap a bolt into the manifold? That is an option, though you really don't want a bolt sticking into the path of the hot exhaust gases if you're after maximizing performance. I'd prefer brazing or welding the manifold shut. Does it matter what I plug the holes with? No, as long as it avoids ...

Secondary air pump is located below the engine to the right. The combi valve is located to the left. There are a pair of black air hoses in between. The combi valve costs roughly 180€ and the air pump 430€. The secondary air pump manufactured by Pierburg (OEM) for VW is known to fault. The early models of the fan enclosure is using rivets instead of bolts. ...
