Water pump issues 

Another common problem that Skoda Superb 1.8 TSI owners have reported is water pump problems. This issue usually happens to Skoda Superb 1.8 TSI’s with lots of miles on the odometer. Since the engine bay in this car is made up of plastic, it can become brittle over time and wears out faster. 

Aside from old age, the engine environment makes the parts around it wear out faster as it gets very hot. One of the most affected parts is the water pump impeller. When the impeller fails, the water pump also fails, and the engine starts to overheat. 

To fix this problem, you should visit a professional mechanic to diagnose and fix the underlying issues. If the impeller is the issue, then it should be replaced. But if most water pump parts are affected, it is best if you replace the entire water pump, flush out the old coolant, and install a new water pump. 

Excess oil usage 

This is another serious issue that Skoda Superb 1.8 TSI users have reported. And since this car uses synthetic oil, it is a costly endeavor that many Skoda Superb owners would like to avoid. This problem is normally caused by pistons and piston rings.

This should be done often to avoid carbon build-up. 

Ignition coil failure 

Even though this issue is not very common on the Skoda Superb 1.8 TSI, some users have reported it. Signs of ignition coil failure can be confusing as they have the same signs with bad spark plugs, including engine misfire, difficulty starting, lack of acceleration, and rough idle. 

To fix this issue, you will have to visit a professional mechanic for diagnosis. If the ignition coils are bad, they should be replaced. And if the spark plugs are also bad, ensure to replace them. 

Vacuum system leak 

Like the water pump, the vacuum system in this engine can also become brittle with age. One of the first parts to wear out in the vacuum system are the hoses. Some of the signs of a bad vacuum system are a drop in engine performance, a hissing sound coming from the engine bay, and a check engine light coming on.
