Audi A4 is a luxury car which is highly popular in the globe and has a refined design, powerful and advanced technology. But it, being like any other vehicle, cannot be considered a machine that will not experience mechanical problems eventually. Audi Engines have been noted to have repeat issues, especially on the older models or those that are more aged.
You are either planning to purchase a used Audi A4 or you have already purchased one, but knowing these common issues will allow you to take precautionary measures and save money in the long-run. Furthermore, when your engine or transmission goes dead, all that may save the day of keeping your Audi running smoothly is to get a good alternative source of replacement, such as Turbo Auto Parts, which is among the best junkyards in the USA to get a used engine and transmission.
We are going to discuss some of the most frequent problems with Audi A4 and their solutions.
Another problem that has been reported the most in Audi A4 is the high consumption of oil. Most of the owners observe that their engines consume more frequent oil top-ups than usual- at times more frequently than once in every 1,000 miles.
It is an especially widespread problem in Audi A4 models that come with the 2.0L engine, and those that were manufactured between the year 2009 and 2012. This will then be caused by worn piston rings or incorrect PCV (Positive Crankcase Ventilation) valves, which will allow oil to spill to the combustion chamber and burn up.
Conditions of Over Usage of Oil:
Regularly required to top up oil in between oil changes.
Blue smoke from the exhaust
Poor fuel efficiency
Smell of burning oil following driving.
Solution:
Audi has recognized this problem with a number of its models even providing extended warranties or service campaigns in some of the years. When out of warranty, then the remedy is normally to change the piston rings or PCV system. The test of oil level should be measured on a routine basis to avoid engine damage.
In case your engine has undergone serious internal wear through lack of oil, then you can install a high quality used engine in a Turbo Auto Parts Audi A4, which will offer you a good and affordable solution.
Audi A4 timing chain tensioner failure is also another problem that is critical to many Audi A4 models, particularly those with a 2.0-liter turbocharged engine. The timing chain maintains camshaft and crankshaft coordination and when the tensioner malfunctions it may result in the engine being destroyed.
Rattling noise from the engine, especially on cold start
Rough idle or misfires
Check engine light illumination
The initial Audi A4s timing chain tensioner models were vulnerable to wear and tear. Once this occurs, the chain may jump or break resulting in bent valves and significant damage to the engine.
The most effective method of avoiding this problem is to replace the tensioner on an anticipatory basis. In the event that you already have a failed engine, a proven and proven used engine can be bought at Turbo Auto Parts at comparatively low costs and get your A4 back on the road within a short time. buy Used Audi A4 Transmission at Turbo auto Parts.
Carbon accumulation is one of the famous challenges with the direct-injection engines, such as those in the Audi A4. Since fuel is introduced in the combustion chamber (as opposed to the intake valves), the intake valves may end up being deposited with carbon deposits in the long run.
Signs of Carbon Build-Up:
Reduced engine performance
Rough idling or hesitation
Poor acceleration
Misfiring or stalling
How to Fix It:
Walnut blasting is the most efficient cleaning method of carbon deposits where the shells of a walnut are crushed and then used to clean the intake valves without destroying them. Doing this kind of service after every 50,000-60,000 miles contributes to optimal engine efficiency.
Although the given issue does not tend to be disastrous, its neglect may cause the long-term loss of performance and the decrease in fuel economy.
Another common problem faced by the owners of Audi A4 is the problem with the ignition coil and spark plug. These elements are in charge of sparking the air-fuel mixture in the engine cylinders. When they malfunction, the engine may misfire, run rough or lose power.
Engine misfire or rough running
Loss of power
Check engine light flashing or steady
Increased fuel consumption
Cause and Fix:
Ignition coils may fail as a result of heat, wear or electric fault. Spark plugs also degrade with time and they require a frequent replacement. It is a simple and fairly cheap fix, but it is fortunate. It is possible to replace coils and plugs simultaneously to ensure that the performance is not interrupted.
When ignition issues are not fixed in good time, they may result in unburned fuel spillage to the exhaust system, destroying the catalytic converter or even the engine.
A water pump is important in ensuring that the engine is cooled by transporting coolant in the engine. The water pump of most Audi A4 is composed of plastic materials that may break or become faulty too soon.
Water pump failure symptoms:
Engine overheating
Leaks of coolants beneath the car.
Whimpering or scratching sounds of the engine bay.
Low coolant warning light
Fix:
Once the water pump starts to malfunction, it should be replaced. To replace the thermostat at the same time is also suggested by many mechanics because it is situated close and fails after approximately the same miles. Always repair the leakage of coolant immediately to prevent overheating which may lead to the destruction of the cylinder head or engine block. In case your engine is highly overheated and wrecked, Turbo Auto Parts sells cheap, tested second-hand Audi A4 engines to regain the performance of your car.
The turbocharged engines in Audi A4 are impressive performing, but the turbocharger may fail with time, because of the starvation of oil, carbon accumulation, or bearing deterioration.
Symptoms of Turbo Failure:
Weakness or retarded acceleration.
Noise of whistling or whining by engine.
Exhaust smoke (blue when there is oil burning).
Check engine light
Cause and Fix:
Failure of turbocharger can easily be linked to improper maintenance of oil. Unclean or poor quality oil may spoil the bearings of the turbo. The most appropriate solution when the turbocharger starts to demonstrate some signs of failure is to replace it or have it rebuilt.
The life of the turbo may be significantly increased by changing the oil with premium synthetic oil on a regular basis. When the internal engine has been damaged by your turbo failure, Turbo Auto Parts can provide you with a reliable used turbocharged engine at a very lower price compared to the dealership replacement.
The PCV (Positive Crankcase Ventilation) valve controls the pressure in the engine and the escape of gases in the crankcase. This is a valve that is identified to fail in the Audi A4 resulting in various performance issues.
Symptoms:
Whistling on the engine.
Rough idle or stalling
Oil leaks
Check engine light
Fix:
Leakage of the vacuum and consumption of oil due to a failed PCV valve. The PCV valve is an easy and inexpensive repair that any person can do, although neglecting the valve may cause more serious problems such as blown seals or gaskets.
In case of the long-term PCV failure, which has led to the oil spill or internal damage, the replacement of the parts which were impacted by it or the entire engine may be required. Turbo Auto Parts will in such situations be able to offer you used engines and transmissions that have been tested and of good quality in order to get your Audi back on the road.
Another common complaint among the Audi A4 owners is the coolant leaks. The cause of these leaks is in most cases the breakdown of water pumps, broken coolant flanges or deteriorated hoses.
Symptoms:
Undercar coolant visible in puddles.
Engine overheating
Sweet odor in the engine compartment.
Low coolant warning light
Fix:
Check the parts of the cooling system periodically and change the worn-out seals and hoses. It is important to use the proper type of coolant and mixing of the coolants may result in corrosion and other damages.
To replace the damaged engine or head gasket on your Audi A4 in case it has been impaired because of overheating due to coolant loss, buy a good used engine at Turbo auto parts, which is fully tested and warranty can be given.
