Audi a5 car owners, especially new ones, often have a question - how to check the audi a5 oil level and what needs to be done for this. Experienced drivers can easily cope with this issue. Our article is written for beginners.

Talk about the incorrect operation of the electronic level arises due to the fact that the owner does not know how to look at it correctly. Some calculate which way the car must go so that they can see this very level. Finally, they come to the conclusion that they need buying a dipstick from a3, and he will finally show them the oil level of the audi a5. After the purchase, two factors begin to confuse the owners: the mismatch of the min / max marks (this immediately indicates the futility of the purchase made) and the fact that the probe rubs against the engine noise. Carried with this acquisition for a certain time, motorists send the purchased dipstick to the garage as an exhibit, and return the a5 plug in its place.

You need to learn one thing - you should not look at the level of the big screen. This shows the information previously saved by the vehicle.

And in what period of time it was, and under what conditions is unknown.
It was 10 min. until now or a week ago? Is the oil glass during measurement? At what temperature did it freeze? It is a little easier for cars that have a working start / stop - when the engine is turned off in forced parking (traffic jams, traffic lights), they measure information about the level. But you cannot be sure that for a short time the car is parked, the oil is completely in the crankcase. Therefore, there is a difference in the displayed information. 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 When you decide to check the oil level on the road - this information is outdated!
It is important 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 t ≈ 90⁰. Look at the oil temperature, not the coolant. The vehicle must be on a level surface.

Describe the measurement procedure

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. We reboot the system with 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 in the MMI:

to item 1.

The indication is not reset because no activation of the hood contact sensors is detected.

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

to item 2.

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

The described problems do not occur in cars with a mileage of more than 5000 km.

to point 3.

Oil level indication:

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

to item 2. Control in serial production, starting from the date of manufacture of the vehicle KN 18/2010

to item 1.

Checking the hood contact sensor:

Open the hood and check the instrument cluster display to see if it is recognized as open.

The operation of the hood contact sensor can also be checked using the VAS tester in Guided Fault Finding >> Function/Component Selection >> Body (Rep. gr. 01; 27; 50 – 97) >> 01 - Systems with self-diagnosis capability >> 09 - Unit control panel for onboard power supply -J519 >> Measured value block 31.

to item 2.

1. Checking the oil level sensor:

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

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

Possibility technical changes currently being tested. No other repair work do not carry out. As soon as possible, the information will be communicated to general information across technical information 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, top up the oil level.

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

Check engine oil level conditions using MMI or radio:

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

Like any other Audi car, the Q5 is technically enough reliable car. On this vehicle a good reliable configuration of the power unit and gearbox is installed. But, as with any machine, for a long and trouble-free operation, you need to take care of it in time.

In the regulations Maintenance Audi Q5 factory manufacturer indicated recommended together with the oil filter, as well as with cabin filter every 15,000 kilometers. But this figure can remain so for drivers who constantly drive in a calm mode and do not put the engine under unnecessary stress.

If you like to sometimes hold the accelerator pedal on the floor or often carry quite large and, accordingly, heavy loads by car, then you should not torment the heart of your car with used grease. You should change the oil every 10,000 - 12,000 kilometers so that its deficiency or does not affect the operation of the car in the future.

Oil capacity for Audi Q5 engines

Since several different gasoline and diesel power units are installed on this car model, namely for you there is a choice of 4 engines, we will consider how many liters of lubricant each of them requires for its normal operation.

So, first let's go through the gasoline power units. Two engines were presented in the gasoline version - a four-cylinder 2.0 TFSI, which, according to the Audi Ku5 operating instructions, needs 4.6 liters of lubricant, and a six-cylinder 3.2 FSI that requires 6.2 liters.

Also available in two versions, again the four-cylinder 2.0 TDI, which requires 5 liters of oil, and the six-cylinder 3.0 TDI, which needs 6.9 liters of lubricant.

Choosing the Right Lubricant

Gradually, we approached an equally important issue, this is the choice of the product with which we will fill filling volume our power plant. Many Audi owners start to roam different forums, but there is no point in this. You just need to open the technical inspection regulations, it has everything you need.

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

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

How to change the oil in the Audi Q5 do it 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 to do is to find drain plug on a pallet. Do not rush to unscrew the bolt on the drain hole, carefully inspect the space near the drain bolt for the presence of oil leaks. If there are no leaks, 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 on a warm engine, since warm oil is not the same as cold oil, and will run away much faster.

We are waiting for the complete devastation of the engine from mining and we are changing the filter.

After you are sure that the motor is empty, you can fill in fresh grease, 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.

Audi Q5 2.0 TFSI quattro insufficient pressure oil (signal light on)

Audi Q5 2.0 TFSI quattro 5 doors SUV, 211 hp, 7automatic transmission, 2008 - 2012 - insufficient oil pressure (signal indicator is on)

Insufficient oil pressure (low oil pressure warning light on)

Reasons for drop in oil pressure

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

The oil warning light can come on for two different reasons: either low oil pressure or low oil level. But what exactly does it mean to catch fire on dashboard oil light, only the instruction manual will help you find out. Helping us is the fact that, as a rule, budget cars do not have a low oil level indicator, but only low pressure oils.

Insufficient oil pressure

If the oil lamp comes on, it means that the oil pressure in the engine is insufficient. As a rule, it lights up only for a few seconds and does not pose a great threat to the motor. For example, it can light up with a strong roll of the car in 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. The first thing to do when the oil pressure light comes on is to check for engine oil. If the oil level is below normal, then this is the reason for the ignition of this lamp. This problem is solved simply - you need to add oil to the desired level. If the light goes out, we rejoice, and do not forget to add oil in time, otherwise it can turn into serious problems.

If the oil pressure light is on, but the oil level on the dipstick is OK, then another reason the light could light up is a failed oil pump. It does not do its job of 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 immediately stopped by pulling to the side of the road or to a safer place and muffled. Why do you need to stop right now? Because if the oil in the engine has dried up significantly, then the latter can stop and break down with the prospect of a very expensive repair. Don't forget that oil is very important to keep the engine running. Without oil, the engine will fail very quickly - sometimes in a matter of minutes of operation.

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

Oil pressure sensor malfunction

Oil pressure on Idling(at about 800 - 900 rpm) should not be less than 0.5 kgf / cm2. Sensors for measuring emergency oil pressure come with a different response range: from 0.4 to 0.8 kgf / cm2. If a sensor with a response value of 0.7 kgf / cm2 is installed on the car, then even at 0.6 kgf / cm2 it will turn on control lamp, signaling a sort of emergency oil pressure in the engine.
To understand whether the oil pressure sensor is to blame for the light bulb 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.
From false positives of the sensor, cleaning helps. It is necessary to unscrew it and thoroughly clean all the oil channels, because the cause of false positives of the sensor may be blockages.

If the oil level is correct and the sensor is OK

First of all, you need to check the oil dipstick and make sure the oil level has not increased since the last check? Does the dipstick smell like gasoline? Perhaps gasoline or antifreeze gets into the engine. Checking the presence of gasoline in the oil is easy, you need to lower the dipstick into the water and see if there are gasoline stains. If so, then you need to contact a car service, it may be necessary to repair the engine.
If there is a malfunction in the engine, which was the ignition of the oil pressure light, this is easy to notice. Engine malfunctions are accompanied by a loss of power, an increase in fuel consumption, exhaust pipe black or blue smoke comes out.

If the oil level is normal, then you should not be afraid of a long indication of low oil pressure, for example, during a cold start. In winter, at low temperatures, this is an absolutely normal effect.
After overnight parking, the oil drains from all highways and thickens. The pump needs a certain time to fill the lines and create the necessary pressure. Oil is supplied to the main and connecting rod journals earlier than to the pressure sensor, so wear of engine parts is excluded. If the oil pressure lamp does not go out for about 3 seconds, this is not dangerous.

What can you do yourself

Engine oil pressure gauge
The problem of low oil pressure is greatly complicated by the relationship of lubricant consumption and level reduction with the overall pressure in the system. In this case, a number of faults can be eliminated independently.

If leaks are found, the problem is fairly easy to localize and fix. For example, an oil leak from under oil filter eliminated by tightening or replacing it. Similarly, the problem with the oil pressure sensor, through which the lubricant flows, is also solved. The sensor is tightened or simply replaced with a new one.
As for oil seal leaks, this will require time, tools and skills. At the same time, you can replace the front or rear crankshaft oil seal with your own hands in your garage with an inspection hole.

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

If the coolant enters motor oil, then you can remove the cylinder head yourself and replace the head gasket, while observing all the recommendations regarding the removal and subsequent tightening of the cylinder head. An additional check of the mating planes will indicate whether it is necessary to grind the head of the block. If cracks are found in the cylinder block or head, repairs are also possible.
As for the oil pump, in case of wear, it is better to immediately replace this element with a new one. It is also not recommended to clean the oil receiver, that is, the part is completely changed.
In the event that the problem in the lubrication system is not so obvious, while 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, and also taking into account an accurate idea of ​​​​what the oil pressure in the engine is measured in and how it is done, you need to prepare in advance optional equipment. Note that in the free market there is a ready-made device for measuring oil pressure in the engine.

As an option, a universal oil pressure gauge "Measure". Such a device is quite affordable, has everything you need in the kit. You can also make a similar device with your own hands. This will require a suitable oil-resistant hose, pressure gauge and adapters.

Ready for measurement or homemade device is connected instead of the oil pressure sensor, after which the pressure readings on the pressure gauge are evaluated. Please note that normal hoses should be used when self-manufacturing it is forbidden. The fact is that the oil quickly corrodes the rubber, after which the exfoliated parts can get into the oil system.

Results

In view of the foregoing, 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" from the engine (pressure increases due to malfunctions of the crankcase ventilation system);
oil pump malfunctions, other breakdowns;
power unit may be heavily worn, etc.
Note that in some cases, drivers resort to using additives to increase oil pressure in the engine. For example, XADO revitalizant. According to the manufacturers, such an anti-smoke additive with a revitalizant reduces oil consumption, allows the lubricant to maintain the required viscosity when heated to high temperatures, restores damaged journals and crankshaft liners, etc.

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

Finally, we add that to avoid many problems with oil system and the engine is helped by the use of only the recommended oil. It is also necessary to select a lubricant taking into account the individual characteristics of operation. Deserves no less attention correct selection seasonal viscosity index (summer or winter oil)

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