Audi 80 Problems
The Audi 80 is a compact executive car that saw its run last for 30 years. Initially sold to the public in 1966, it shared the Volkswagen Group B platform with the Volkswagen Passat. There were several trims made available by Audi for the Audi 80, boasting different combustion engines. Since it has been around for more than 40 years, some of its common problems are well-documented. Here are some problems that Audi 80 owners have been experiencing with their car.
There have been complaints about the Audi 80's engine misfiring and losing power. It's understandable if the Audi 80 is overloaded since it's already an old car. However, this problem happens even if it's on cruising speed or idling. Whenever it misfires, it appears to stall, and then it comes back to life again. In addition, there have been separate reports of it having engine problems caused by faulty fuel injections and air leaks. Models that are having this problem is the 1991, 1992 and 1994 Audi 80s.
The constant velocity balls and joints are needing frequent servicing. Technicians have recommended that these parts should be inspected at each service done with the Audi 80. This is for repairing the torn cv boots as early as possible in order to prevent replacing the CV half shaft or cv joint. Replacing the CV half shaft is costlier than repairing the cv boots.
In addition, both 1990 and 1991 Audi 80 models were recalled on January 29, 1993 for oil problems with the axle assembly in the power train. The recall covered the draining and replacement of the differential oils with oil formulated for higher performance. This was made to prevent pre-mature bearing failure brought about by quick oil evaporation. An estimated 152,000 units were affected.
On April 6, 1990, some 6600 Audi 80s were recalled for a faulty column locking anti-theft device. Some Audi 80s were fitted with improperly manufactured steering lock bolts. If it breaks, the steering wheel will remain locked even if the car has been started already. This would result to a total loss in steering control which could lead to accidents. The recall sought to replace the whole steering lock assembly, including a modified lock bolt.
My Audi 80 is not starting properly. It doesn't seem to be running on all cylinders. Where do I start looking to find the problem?
In order to troubleshoot this, you need to start at the beginning of the line, then the battery, before working your way to the back of your Audi 80. First, check your fuses to make sure that all of them are in good condition, and replace the ones that are blown. If that doesn't help, inspect the battery connections. Over time, they tend to become dirty or corroded, which breaks the connection that the battery has with the rest of the car. Try cleaning the battery posts before attempting to start your car again. You should also check the starter to see if it's been affected by the corrosion. You can run a test by holding a circuit tester lead on the wire that engages the starter. Then have a friend turn the key while you check the current. If you're getting current to the starter but it's not spinning, then it needs to be replaced.
My Audi 80 stalls while on idle or when stopped in traffic. What's wrong with my car?
If your Audi 80 stalls while idling or stopped in traffic, then your car's engine is not idling fast too much or is being bogged down by a load created by the air conditioning compressor or alternator. If the A/C compressor is binding up, it may be pushing down the engine when it's engaged. If you notice that your engine stalls while idling and while the A/C is on, then the issue lies with the compressor. Make sure that this component is properly lubricated and has not shown any signs of wear or you will have to replace it. You should also take care not to put too much refrigerant in the A/C system. Another possible cause for the stalling is that the fuel mixture is either too rich or too lean, which causes the engine to run poorly.
I have an Audi 80 and it has been overheating a lot lately. What can I do to fix this and prevent it from happening again?
There might be a leak in your cooling system. If it tends to overheat even in normal weather when it's not too hot and while in traffic, you might have to add liquid to the system, replace the thermostat, adjust or replace the accessory belt, or check the water pump. If these do not help, check the radiator cap. When the gasket on the cap deteriorates, it lets pressure escape, which causes your car's cooling system to malfunction. You can have a mechanic test the radiator cap, but you can also do it yourself if you can get your hands on a radiator pressure tester. Take out your radiator cap and place it on one end of the tester while the cap adapter included in the tester is on the other end. Pump the tester and watch the gauge to see if it holds the pressure. Ideally, the gauge should reach at least 15 pounds. If the gauge starts to drop or doesn't progress as you pump the tester, then the pressure cap is not functioning properly.
