Audi Catalytic Converter Parts and Q&A
- Q: What are the important facts owners should be aware of to ensure the proper functioning of a catalytic converter throughout its service life on Audi A3?A:The catalytic converter is a durable and very easy tool and needs no maintenance yet the owners should take note of few facts that they should observe to have proper operations of this device during the life of its use. One should also never use leaded or lead-replacement petrol because lead and other additives may coat the precious metals reducing their efficiency and eventually destroying the converter. It is important to maintain the ignition and fuel systems in an efficient state as per the schedule of the manufacturer. In case of misfiring of the engine, there should be limited driving until it is corrected. Pushing or towing of the car may wet the catalytic converter with unburnt fuel and therefore may cause overheating when the engine is started. One should not switch off the ignition when the engine speed is high and must not use fuel or engine oil additives that can damage the converter. It is not recommended to keep on driving the car and keep burning oil to the point where blue smoke can be seen. The catalytic converter has its very high temperatures and therefore, after a long running period, one should not park the car in dry undergrowth, long grass or stacked leaves. Also, converter is delicate and should not be hit with tools when servicing it, and one must be keen when handling it. Sulphurous odor Sometimes a smell of rotten eggs may be detected at the exhaust, but this is due not to the converter but to the sulfur in the fuel. With a properly driven and well-maintained car, the lifespan of the catalytic converter should take up to 50,000100,000 miles, and once it stops working, it has to be changed.
- Q: How to remove and install the catalytic converter on Audi A4?A:In four cylinder models, the starting point would be to remove the engine cover of 1.8L models and maybe remove the air filter housing to create ease of access. Disconnect the electrical connectors of the upstream and downstream oxygen sensors that might need to have the coolant expansion tank detached without the removal of the hoses. Take out the oxygen sensors of the catalytic converter and then remove the attaching parts that hold the front exhaust pipe in place on top of the catalytic converter. Lift the car on jackstands, loosen the bolts holding the front exhaust pipe support bracket, and then the three bolts holding the lower catalytic converter flange to the front exhaust pipe, and then take away the catalytic converter and dispose the old flange gaskets. The reverse order of installation should be adopted making sure that new gaskets and self-locking nuts are used. In case of V6 models, that one starts with the cover of the rear engine by taking it off then continue with the left-side catalytic converter by taking off the little cover, remove the engine coolant level sensor and the coolant expansion tank. Reach the oxygen sensor electrical connections, and in the case of right catalytic converter, do the same action, but remove the air filter housing. Take the top nuts holding the converter to the exhaust manifold, lift the vehicle, and take out the front wheel. Disconnect the exhaust system and, on AWD models, proceed to further steps to assist and support the transmission by lowering it. Lastly, unbolster the catalytic converter and replace it with the new one making sure that all the fasteners are tightened. In the case of 3.2L V6 engines, it includes the removal of the rear engine cover, the disconnection of the coolant level sensor on the left engine bank, and the same procedure on both the catalytic converters, making sure that the transmission is properly supported and that the entire assembly of the exhaust pipe is taken off carefully before attaching it.
