Advantages

In general, the described engine has outstanding technical characteristics, which make it so recognizable among motorists from all over the world. For example, it is quite a long service life (300+ km), reliability of all constituent elements. Economical fuel consumption is a very important aspect for any person, especially if the engine has such a high power indicator.

Disadvantages

Unfortunately, it is not without problems. There are not so many of them, all of them are solved by quite simple methods, but still we recommend you to familiarize yourself with this information, because it will definitely help you in case you decide to become the owner of a car with this power unit.

Firstly, there are often problems with the swirl flaps. Namely, corking. Unlike M-series engines, these are not able to fly into the motor. However, such encrustation will cause the flaps to stop moving, causing the car to fail to run evenly and produce various errors as it operates. Often the source of the problem lies in the valve (EGR). It should be periodically cleaned or removed, because often at a mileage of 100,000 km the manifold can be completely clogged with dirt.

After reading numerous reviews of real owners, you will see complaints about various extraneous sounds, including quite loud noises. What is this due to? Often, the crankshaft damper fails. This happens after about 100 thousand kilometers. It is necessary to make a timely replacement. After 200 thousand kilometers, extraneous noises coming from the rear area of the engine, can report the need to inspect the timing chain. It is quite possible that it will need to be replaced.

Even these few problems are quite avoidable if you do timely diagnostic inspections and address problems as they arise. The engine is generally very reliable, and it is quite likely that it will not cause you any inconvenience at all. However, if any, do not “self-medicate” the car. Contact a specialist who will be able to provide you with competent assistance.
