Owners of an Audi A5, especially new ones, often have a question: how to check the oil level of an Audi A5 and what needs to be done for this. Experienced drivers can easily cope with this issue. Our article is written for beginners.

Discussions about the malfunction of the electronic level arise because the owner does not know how to look at it correctly. Some calculate what path the machine must take so that they can see this very level. As a result, they come to the conclusion that it is necessary buying a dipstick from A3, and it will finally show them the oil level of the Audi A5. After the purchase, owners begin to be confused by two factors: the mismatch of min/max marks (this immediately indicates the uselessness of the purchase made) and the fact that the dipstick rubs against the engine noise. After fiddling with this acquisition for a certain time, car enthusiasts send the purchased dipstick to the garage as an exhibit, and in its place they return the A5 plug.

One thing you need to understand is that you shouldn’t look at the level of the big screen. This shows the information previously saved by the car.

And in what period of time this happened and under what conditions is unknown.
It was 10 minutes. until now or a week ago? Did the oil run out during measurement? At what temperature did the measurement take place? It’s a little easier for cars that have a working start/stop - when they turn off the engine in forced stops (traffic jams, traffic lights), they measure information about the level. But you cannot be sure that during a short period of time the car is parked, the oil will be completely in the crankcase. Therefore, there is a difference in the information shown. The car does not measure the level when the engine is running! When you decide to check the oil level on the road, this information is out of date!
The important thing is that the measurement conditions must be the same, then the results can be compared. This should be done after the engine is turned off (about 5 minutes) and oil temperature ≈ 90⁰. You need to look at the temperature of the oil, not the coolant. The car must be parked on a horizontal surface.

We describe the measurement procedure itself

1. Turn on the ignition. Press and hold two buttons: “setup” and “car”.
2. Release the buttons and wait for the hidden menu to appear.
3. Go to “car”, then to “carextdtviselist”, then to “oil level gauge”.
4. Next, go to “carmenuoperation”, then to “oil level gauge” and set it to the fifth level.
5. Press and hold the “return” and “car” buttons at the same time to close the hidden menu.
6. Reboot the system using a combination of buttons. Go to “oil level”, we will be shown the oil level in the internal combustion engine.

The following information may appear in the instrument cluster or MMI:

to point 1.

The indication is not reset because the hood contact sensors are not detected.

The hood needs to be opened for at least 30 seconds , only then will a reset occur in the engine control unit!

to point 2.

1. There is no damper cup on the oil level sensor. In this case, the sensor gives incorrect readings, which immediately after passing the minimum distance equal to with a gasoline engine 50 km, and with a diesel engine - 100 km , are also displayed in the instrument cluster and/or in the MMI.

The described problems do not occur in cars with mileage of more than 5,000 km.

to point 3.

Oil level indication:

Both messages are reset only if a static oil level is again detected between the MIN marks. and MAX.

to point 2. Control in mass production, starting from the vehicle release date KN 18/2010

to point 1.

Checking the hood contact sensor:

Open the hood and check in the instrument cluster display whether it is recognized as open.

The operation of the bonnet contact sensor can also be checked using the VAS tester in Guided Fault Finding >> Selecting a function/component >> Body (rep. gr. 01; 27; 50 – 97) >> 01 - Systems with self-diagnosis capability >> 09 - Unit control for on-board power supply -J519 >> Measured value block 31.

to point 2.

1. Checking the oil level sensor:

Replace the oil level sensor only if the damper cap is missing!

If the measured value is higher than 75 mm you need to lower the engine oil level.

The possibility of technical changes is currently being tested. Do not carry out any other repair work. Whenever possible, information will be made available to the general public through Technical Product Information (TPI).

to point 3.

Before checking the static engine oil level in the MMI or radio display, check the actual oil level according to ELSA "Inspection service and care", if necessary, bring the oil level to normal.

The engine oil level can be checked in the MMI or radio >> CAR function button >> Oil level.

Check engine oil level conditions using the MMI or radio:

Finally, the current oil level is determined and the warning indication in the instrument cluster is reset.

Causes of drop in oil pressure

There is a light on the instrument panel that indicates emergency oil pressure in the engine. When it lights up, it is a clear sign of a problem. We'll tell you what to do if the oil pressure light comes on and how to fix the problem.

The oil check light can come on for two different reasons: either low oil pressure or low oil level. But what exactly does the oil light on the dashboard mean, only the operating instructions will help you find out. It will help us that, as a rule, budget cars do not have a low oil level indicator, but only a low oil pressure indicator.

Insufficient oil pressure

If the oil light comes on, this means insufficient oil pressure in the engine. As a rule, it lights up only for a few seconds and does not pose a great threat to the engine. For example, it can light up when the car rolls heavily during a turn or during a cold start in winter.

If the low oil pressure light comes on due to a low oil level, then this level, as a rule, is already critically low. First of all, when the oil pressure light comes on, check for the presence of engine oil. If the oil level is below normal, then this is the reason for this lamp to light up. This problem can be solved simply - you need to add oil to the required level. If the light goes out, we rejoice, and do not forget to add oil on time, otherwise this could result in serious problems.

If the oil pressure light is on, but the oil level on the dipstick is fine, then another reason why the indicator could light up is a failed oil pump. It does not do its job of ensuring sufficient oil circulation in the engine lubrication system.

In any case, if the oil pressure or low oil level light comes on, the car must be stopped immediately by pulling to the side of the road or to a safer place and turning off. Why do you need to stop right away? Because if the oil in the engine has depleted significantly, then the engine may stop and break down, with the prospect of very expensive repairs. Don't forget that oil is very important to keep your engine running. Without oil, the engine will fail very quickly - sometimes in just a few minutes of operation.

This situation also occurs when the engine oil is changed to new one. After the first start, the oil pressure light may come on. If the oil is of good quality, it should go out within 10-20 seconds. If it does not go out, the reason is a defective or non-functioning oil filter. It needs to be replaced with a new quality one.

Oil pressure sensor malfunction

The oil pressure at idle speed (at approximately 800 - 900 rpm) should not be less than 0.5 kgf/cm2. Sensors for measuring emergency oil pressure come with different response ranges: from 0.4 to 0.8 kgf/cm2. If a car is equipped with a sensor with a response value of 0.7 kgf/cm2, then even at 0.6 kgf/cm2 it will turn on a warning lamp, signaling a kind of emergency oil pressure in the engine.
To understand whether the oil pressure sensor is to blame for the light coming on or not, you need to increase the crankshaft speed to 1000 rpm at idle. If the light goes out, then the oil pressure in the engine is normal. If not, then you need to contact specialists who will measure the oil pressure with a pressure gauge, connecting it instead of the sensor.
Cleaning the sensor helps prevent false alarms. You need to unscrew it and thoroughly clean all the oil channels, because the cause of false alarms of the sensor may be due to blockages.

If the oil level is normal and the sensor is working

First of all, you need to check the oil dipstick and make sure that the oil level has not increased since the last check? Does the dipstick smell like gasoline? It is possible that gasoline or antifreeze is getting into the engine. It’s easy to check the presence of gasoline in the oil; you need to dip the dipstick in water and see if gasoline stains remain. If yes, then you need to contact a car service; the engine may need to be repaired.
If there is a malfunction in the engine, which is caused by the oil pressure light coming on, it is easy to notice. Engine malfunctions are accompanied by loss of power, increased fuel consumption, and black or blue smoke coming out of the exhaust pipe.

If the oil level is normal, then there is no need to worry about a prolonged indication of low oil pressure, for example during a cold start. In winter, at low temperatures, this is an absolutely normal effect.
After parking overnight, the oil drains from all lines and thickens. The pump needs a certain time to fill the lines and create the necessary pressure. Oil reaches the main and connecting rod journals earlier than the pressure sensor, so wear of engine parts is eliminated. If the oil pressure light does not go out for about 3 seconds, it is not dangerous.

What you can do yourself

Measuring engine oil pressure
The problem of low oil pressure greatly complicates the relationship between lubricant consumption and level drop and the overall pressure in the system. In this case, a number of malfunctions can be eliminated independently.

If leaks are detected, the problem is quite easy to localize and solve. For example, oil leakage from under the oil filter can be eliminated by tightening or replacing it. The problem with the oil pressure sensor, through which lubricant flows, is solved in a similar way. The sensor is tightened or simply replaced with a new one.
As for seal leaks, in this case you will need time, tools and skills. In this case, you can replace the front or rear crankshaft oil seal with your own hands in your garage with an inspection hole.

Oil leaks from under the valve cover or in the pan area can be eliminated by tightening fasteners, replacing rubber gaskets, and using special engine sealants. Violation of the geometry of the connecting planes or damage to the valve cover/pan will indicate the need to replace such parts.

If the coolant gets into the engine oil, then you can remove the cylinder head yourself and replace the head gasket, while following all the recommendations regarding the removal and subsequent re-covering of the cylinder head. An additional check of the mating planes will indicate whether the cylinder head needs to be ground. If cracks are found in the cylinder block or head, repairs are also possible.
As for the oil pump, if this element wears out, it is better to immediately replace it with a new one. It is also not recommended to clean the oil receiver, that is, the part is completely changed.
In the case where the problem in the lubrication system is not so obvious, and you have to repair the car yourself, then at the very beginning you should measure the oil pressure in the engine.
To solve the problem, as well as taking into account an accurate understanding of where the oil pressure in the engine is measured and how it is done, additional equipment must be prepared in advance. Note that there is a ready-made device for measuring engine oil pressure available for free sale.

As an option, a universal oil pressure gauge will “Measure”. This device is quite affordable and comes with everything you need. You can also make a similar device with your own hands. To do this, you will need a suitable oil-resistant hose, pressure gauge and adapters.

To measure, a ready-made or home-made device is connected instead of an oil pressure sensor, after which the pressure readings on the pressure gauge are assessed. Please note that ordinary hoses cannot be used for self-production. The fact is that oil quickly corrodes rubber, after which the detached parts can get into the oil system.

Results

Taking into account the above, it becomes clear that the pressure in the lubrication system can drop for many reasons:
oil quality or loss of its properties;
leaks of oil seals, gaskets, seals;
oil “presses” out of the engine (pressure increases due to malfunctions of the crankcase ventilation system);
oil pump malfunctions, other breakdowns;
the power unit may be badly worn, etc.
Note that in some cases, drivers resort to using an additive to increase oil pressure in the engine. For example, XADO revitalizant. According to manufacturers, such an anti-smoke additive with revitalizant reduces oil consumption, allows the lubricant to maintain the required viscosity when heated to high temperatures, restores damaged crankshaft journals and liners, etc.

As practice shows, additives cannot be considered an effective solution to the problem of low pressure, but as a temporary measure for old worn-out engines, this method may be suitable. I would also like to draw your attention to the fact that the blinking oil pressure light does not always indicate problems with the internal combustion engine and its systems.
It's rare, but it does happen that electrical problems arise. For this reason, the possibility of damage to electrical components, contacts, pressure sensor or the wiring itself should not be ruled out.

Finally, we would like to add that using only the recommended oil helps to avoid many problems with the oil system and engine. It is also necessary to select a lubricant taking into account individual operating conditions. The correct selection of viscosity index for the season (summer or winter oil) deserves no less attention.

Engine oil and filters must be changed correctly and done strictly according to regulations, since an increase in the service interval leads to severe contamination of the lubrication system. In this case, decomposition products and other deposits actively settle on the surfaces of parts and channel walls, clogging filters and the oil receiver mesh. Under such conditions, the oil pump may not provide the required pressure, causing oil starvation and significantly increasing engine wear.

Specifications

Technical parameters of Audi Q5 2.0 TFSI quattro / Audi Q5 in a 5-door body. SUV with a 211 hp engine, 7 automatic transmission, produced from 2008 to 2012.

Like any other Audi car, the Q5 model is technically a fairly reliable car. This vehicle has a good reliable powertrain and gearbox configuration. But, as with any machine, for long and trouble-free operation you need to take care of it in a timely manner.

In the Audi Q5 maintenance regulations, the manufacturer indicated the recommended service along with the oil filter, as well as the cabin filter, every 15,000 kilometers. But this figure may remain the same for drivers who constantly drive in a relaxed mode and do not subject the engine to unnecessary loads.

If you sometimes like to hold the accelerator pedal to the floor or often transport fairly large and therefore heavy loads in your car, then you should not torment the heart of your car with waste lubricant. You should change the oil every 10,000 - 12,000 kilometers so that its deficiency does not affect the car’s performance in the future.

Oil volume for Audi Q5 engines

Since this car model is equipped with several different gasoline and diesel power units, and you have a choice of 4 engines, we will look at how many liters of lubricant each of them requires for its normal operation.

So, first, let's go through the gasoline power units. In the gasoline version, two engines were presented - a four-cylinder 2.0 TFSI, which, according to the Audi Q5 operating instructions, requires 4.6 liters of lubricant, and a six-cylinder 3.2 FSI, which requires 6.2 liters.

Also available in two versions, again this is a four-cylinder 2.0 TDI, which requires 5 liters of oil, as well as a six-cylinder 3.0 TDI, which requires 6.9 liters of lubricant.

Selecting the right lubricant

Gradually we came to an equally important issue, this is the choice of the product with which we will fill the filling volume of our power unit. Many Audi owners begin to wander around various forums, but there is no point in this. You just need to open the technical inspection regulations, it contains everything you need.

Having analyzed this interesting book, we can see that the manufacturer has clearly indicated which fluid is well suited for changing engine oil, namely: the original VAG 5W-30 LongLife III oil or the analogue AV-L 5W-30 LongLife III.

There is no need to come up with something of your own and spend a long time searching for the right lubricant, since the manufacturer indicates the product that will fully preserve the life of all components of the engine and will help it serve for a long time.

How to change the oil in an Audi Q5 yourself

First of all, disconnect the battery so that there are no errors on the speedometer screen later. When you are already at the bottom of the car, the first thing you need to do is find the drain plug on the pan. Do not rush to unscrew the bolt on the drain hole; carefully inspect the space around the drain bolt for the presence of oil leaks. If there are no drips, then you can safely open the drain plug, but if traces of drips are visible, you can unscrew it, but you will need to immediately change the gasket on the drain bolt. It is advisable to drain the engine on a warm engine, since heated oil has a different quality than cold oil and will drain much faster.

We wait until the engine is completely empty from working and change the filter.

Once you are sure that the engine is empty, you can add fresh lubricant, and after completing this procedure, let your car idle for a while.

As a result, we see that this procedure does not cause any particular difficulties, and in principle you can do everything yourself, if you wish.
