2.0 TFSI oil consumption | 1.8 TFSI oil consumption

The concern engine of the VAG Group:

Do you notice oil consumption on your Audi, VW, Škoda or Seat 1.8 or 2.0 TFSI? Then you are one of almost 800,000 people affected. Between the beginning of 2008 and mid-2011, more than 800,000 vehicles were fitted with these engines.

But why do you consume 1.8 | 2.0 TFSI vehicle so much oil?

At the 1.8 | 2.0 TFSI oil consumption engine that is installed in your system, oil scraper rings (piston rings) that are too thin were installed to reduce friction and improve exhaust gas values, but these then wear out prematurely and become clogged. As a result, the oil consumption increases steadily up to the point of major engine damage.

What is the oil scraper ring for?

The oil control ring encloses each piston in your engine and ensures that the piston skirt is lubricated and that the oil does not go further up into the combustion chamber. Because the oil scraper ring is too low and the bore is too small, the bores become clogged with carbon deposits. As soon as the drainage hole in the oil scraper ring begins to clog, more and more engine oil is transported past the scraper ring into the combustion chamber and is also burned here. The result of this is that even more oil carbon residues are formed in the combustion chamber. For you, this becomes noticeable through an ever-increasing oil consumption.

Since oil is constantly being burned, the temperature in the combustion chamber rises. This can cause valve seats to warp. In addition, the valves stretch or the valve disks tear. The piston crown can also melt. Consequently, the problem arises that your engine runs out of compression.

How to solve the problem?

We solve your 1.8 | 2.0 TFSI oil consumption problem as follows: In our replacement engines, we install modified pistons with wider three-part steel lamellar oil rings (SLF)*. Wider lamellae of the oil scraper rings ensure optimum oil flow. Furthermore, our replacement engines receive a new, reinforced timing chain with a modified tensioner, since unfortunately the timing chain also causes problems with this engine.

How is the oil consumption calculated?

The frequently used statement that an engine does not consume any oil is fundamentally wrong. But which consumption is normal and which is increased?

Every car manufacturer specifies recommended or limit values ​​for oil consumption for its engines. If you suspect that the oil consumption is too high, then you should ask your engine manufacturer about this value. Information about this value can also be found in workshop manuals and operating instructions. If you do not have precise information, you can use the normal consumption of 0.1% - 0.5% of the fuel consumption as a basis. This is calculated as follows:

Your car uses about 8 liters of fuel per 100 km. This corresponds to 80 liters of fuel per 1,000 km. With an oil consumption in your vehicle of 0.1% - 0.5%, this corresponds to 0.08 - 0.4 liters of oil per 1,000 km.

It should be noted that diesel engines consume more oil than petrol engines. Turbocharged engines also use slightly more engine oil. Here the engine oil is also required for the lubrication of the turbocharger. In the life cycle of an engine, the consumption of engine oil increases. It is therefore normal for older engines to consume a little more oil.

But why overhaul the engine and not just replace the piston rings?

Often only the piston rings are changed in these engines. As a result, however, many customers have already reached us who subsequently suffered engine damage due to a skipped timing chain. Since the timing chain problem is known, our replacement engines all get a new, modified timing chain. In order to be able to change the piston rings on your vehicle, the engine must be removed. The work and consequently the costs for changing the piston rings and the timing chain hardly make any difference to a complete general overhaul of the engine. In the course of the engine overhaul, all wearing parts are checked and replaced if necessary. You will then have a new engine. So that you can enjoy your vehicle for many years to come!
