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 long and trouble-free operation, you need to take care of it on time.

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

If you sometimes like to hold the accelerator pedal in the floor or you often transport large enough and therefore heavy loads by car, then you should not torment the heart of your car with used lubricant. The oil should be changed every 10,000 - 12,000 kilometers, so that its deficiency or does not affect the operation of the car in the future.

Oil volume 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 their normal operation.

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

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

Choosing the right lubricant

Gradually, we came to an equally important question, this is the choice of the product with which we will fill filling volume our powertrain. Many Audi owners start wandering around different forums, but that doesn't make any sense. 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 clearly indicated which fluid is well suited for changing engine oil, namely: original oil VAG 5W-30 LongLife III or analogue of AV-L 5W-30 LongLife III.

There is no need to invent something of his own and to 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 the engine components and help it serve for a long time.

How to change oil in an Audi Q5 with your own hands

First of all, disconnect the battery so that later there are no errors on the speedometer screen. When you are already at the bottom of the car, the first step is to find the drain plug on the pallet. Do not rush to unscrew the bolt on the drain hole, inspect carefully the space near the drain bolt for the presence of oil drips. If there are no drips, then you can safely open the drain plug, but if you see traces of drips, you can unscrew it, but you will have to immediately change the gasket on the drain bolt. It is advisable to drain it on a warm engine, since the heated oil is not the same as the cold one, and will run away much faster.

We are waiting for the complete emptying of the engine from working off and we are changing the filter.

Once you are confident that the engine is empty, you can refill with fresh grease, and at the end of this procedure, allow your car to 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.

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

to item 1.

The indication is not cleared because no actuation of the bonnet contact sensors is detected.

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

to item 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 at gasoline 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 arise in cars with a mileage of more than 5000 km.

to item 3.

Oil level indication:

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

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

to item 1.

Checking the bonnet contact sensor:

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

The function of the bonnet contact sensor can also be checked using the VAS tester in Guided Fault Finding >> Function / component selection >> Body (repair gr. 01; 27; 50 - 97) >> 01 - Systems with self-diagnosis capability >> 09 - Block management for on-board network-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!

When the measured value is higher 75 mm the engine oil level must be lowered.

Possibility technical changes is currently being tested. No other renovation works do not conduct. Whenever possible, information will be communicated to general information through the technical product information (TPI).

to item 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", top up the oil level if necessary.

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 indication in the instrument cluster is reset.

Owners of an audi a5 car, especially newly-made 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 easily deal 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 people calculate which way the car must go in order for them to see this very level. As a result, they come to the conclusion that they need buying a dipstick from an a3 and it will finally show them the oil level of an audi a5. After the purchase, the owners begin to be confused by two factors: the mismatch of the min / max marks (this immediately speaks of the uselessness of the purchase made) and the fact that the probe rubs against the motor Shumka. Having spent some time with this acquisition, motorists send the purchased probe to the garage as an exhibit, and the a5 plug is returned in its place.

One thing to learn - you shouldn't look at the level big screen... Information saved by the vehicle previously is shown here.

And in what period of time it was, and under what conditions it is not known.
It was 10 minutes. up to this point or a week ago? Is the oil glass during the measurement? At what temperature did the measurement take place? Cars that have a working start / stop are a little easier - when the engine is turned off in forced parking (traffic jams, traffic lights), they measure the level information. But one cannot be sure that for a short time when the car is parked, the oil is completely in the crankcase. Therefore, there is a difference in the information displayed. The vehicle 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 off (approx. 5 min.) And oil t ≈ 90⁰. It is necessary to watch the temperature of the oil, not the coolant. The vehicle must be on a level 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 the "carmenuoperation", then to the "oil level gauge" and set it to the fifth level.
5. Press and simultaneously hold the "return" and "car" buttons to close the hidden menu.
6. Reboot the system with a combination of buttons. Go to the "oil level", we will be shown the oil level in the internal combustion engine.

Reasons for a drop in oil pressure

There is a light on the dashboard that signals an emergency oil pressure in the engine. When it lights up it is a clear sign of a malfunction. We will tell you what to do if the oil pressure lamp comes on and how to fix the problem.

The oil indicator light can come on for two different reasons: either low oil pressure or low oil level. But what exactly does the lit on dashboard oil light, only the instruction manual will help to find out. It will help us 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 can light comes on, this means that there is insufficient oil pressure in the engine. As a rule, it lights up for only a few seconds and does not pose a great threat to the motor. For example, it can light up when the vehicle rolls heavily in a corner or during a cold start in winter.

If the low oil pressure light comes on due to low level oil, 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 the presence of engine oil. If the oil level is below normal, then this is the reason for the lighting of this lamp. This problem can be solved simply - you need to add oil to the desired level. If the light goes out, we rejoice, and do not forget to top up the oil in time, otherwise it can turn into serious problems.

If the oil pressure light is on, but everything is in order with the oil level on the dipstick, then another reason the indicator could light up is a failed oil pump. It does not do its job of circulating enough oil in the engine's lubrication system.

In any case, if the oil pressure or low oil level light comes on, the machine must be stopped immediately by pulling over to the side or to a safer place and turned off. Why stop right away? Because if the oil in the engine has dried up significantly, then the latter can stop and break down with the prospect of very expensive repairs. Remember that oil is very important to keep your engine running. Without oil, the engine will fail very quickly - sometimes in a matter of minutes.

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

Faulty oil pressure sensor

Oil pressure on Idling(at about 800 - 900 rpm) should not be less than 0.5 kgf / cm2. Sensors for measuring emergency oil pressure are available with different response ranges: 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 a control lamp, signaling, as it were, an emergency oil pressure in the engine.
To understand whether the oil pressure sensor is to blame for the light bulb lighting up 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 a specialist who will measure the oil pressure with a pressure gauge, connecting it instead of the sensor.
Cleaning helps from false alarms of the sensor. It is necessary to unscrew it and thoroughly clean all the oil channels, because the cause of false alarms of the sensor may be in blockages.

If the oil level is normal and the sensor is good

First of all, you need to check the oil dipstick and make sure that the oil level has not increased after the last check? Does the dipstick smell like gasoline? Perhaps gasoline or antifreeze gets into the engine. It is easy to check for the presence of gasoline in the oil; you need to lower the dipstick into the water and see if gasoline stains remain. If so, then you need to contact a car service, the engine may need to be repaired.
If there is a malfunction in the engine, which was caused by the oil pressure light coming on, it 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 prolonged indication of low oil pressure, for example, during a cold start. In winter, at low temperatures, this is an absolutely normal effect.
After an overnight stay, oil drains from all highways and thickens. The pump takes a certain amount of time to fill the lines and build up the required pressure. Oil is supplied to the main and connecting rod journals earlier than to the pressure sensor, therefore, wear of engine parts is excluded. If the oil pressure lamp does not go out for about 3 seconds, it is not dangerous.

What can you do yourself

Measurement of engine oil pressure
The problem of low oil pressure is greatly complicated by the relationship of lubricant flow and low level 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 solve. For example, oil leak from under oil filter eliminated by tightening or replacing it. The problem with the oil pressure sensor, through which the lubricant flows, is solved in a similar way. The sensor is tightened or simply replaced with a new one.
As for oil seal leaks, in this case it will take 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 pit.

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

If coolant enters engine 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 surfaces will indicate whether you need to grind the block head. If cracks in the cylinder block or head are found, repair is 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, 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 the exact idea of ​​what the oil pressure in the engine is measured in and how it is done, it is necessary to prepare in advance optional equipment... Note that there is a ready-made device on the free market for measuring the oil pressure in the engine.

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

For measurement, ready-made or homemade device is connected instead of the oil pressure sensor, after which the pressure readings on the manometer are evaluated. Please note that ordinary hoses should be used when self-production it is forbidden. The fact is that the oil quickly corrodes the rubber, after which the detached parts can get into the oil system.

Outcomes

Given 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" from the engine (pressure rises due to malfunctions of the crankcase ventilation system);
oil pump malfunctions, other breakdowns;
power unit may be badly worn, etc.
Note that in some cases, drivers resort to the use of an additive to increase the 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, an effective solution to the problem of low pressure additives cannot be considered, but as a temporary measure for old worn out motors, this method may be suitable. I would also like to draw your 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 elements, contacts, pressure sensor or the wiring itself should not be ruled out.

Finally, we 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 the individual characteristics of operation. Deserves no less attention and 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. In this case, decay products and other deposits actively settle on the surfaces of parts and channel walls, clog filters and the oil receiver grid. The oil pump in such conditions may not provide the required pressure, oil starvation occurs and the wear of the motor increases significantly.
