Seat Leon

The 1.8 liter TSI unit proved to be the most trouble-free gasoline engine, and its only characteristic “sore”, which, however, is inherent in all TSI engines, is that individual ignition coils may fail after a run of 100 thousand km. Another feature of all turbocharged units is oil consumption. The norm is considered to be up to 2-4 liters per 10 thousand km, although for lovers of active driving it can be noticeably large.


Diesel modifications of the Leon TDI are also common. In general, such versions have proven to be quite reliable, although several weaknesses have been identified in them. So, over time, the exhaust gas recirculation system clogs in them (the bypass valve wedges). In some cases, the problem is solved by cleaning the system, and if it doesn’t help, then it is “jammed” and then the ECU is “flashed”.


Another problematic place is the particulate filter may become clogged. Since the new one is expensive, many owners solve the problem radically - they cut it out of the exhaust system, weld in a flame arrester instead of it and “flash” the ECU.

The most problematic Seat Leon engines are the 1.2 and 1.4 liter TSI units produced before 2014 - they can cause serious trouble to their owners. They are mainly associated with the timing chain, which can slip, provoking a fatal meeting of valves with pistons and forcing the engine to make an expensive “capital”.


Firstly, it does not differ in particular durability - it stretches to a run of 120-150 thousand km. Secondly, it can slip even with a slight involuntary pitching of a car standing on a slope in gear.


This is due to the design feature of the units - the necessary chain tension is created by the hydraulic tensioner from the oil pressure on the running engine. If it is turned off, then during prolonged parking, the tension of the chain weakens and there is a high risk of slipping. In order to avoid trouble, minders are advised to use the parking brake without fail.

But the most unreliable was the 1.4 TSI unit for 140 “horses”, equipped with a turbine, paired with a mechanical supercharger. Thanks to this design, it is deprived of the so-called turbo lag inherent in engines equipped only with a turbine, and at the same time provides the car with locomotive traction literally from the very bottom.


According to servicemen, in this unit, the designers did not correlate the structural strength margin with a high power-to-weight ratio. As a result, the crankshaft liners wear out prematurely and the pistons burn out. Moreover, such troubles can happen at any run, although, as a rule, this happens to those who like to trample the gas pedal. But his fellow 1.4 TSI (122 hp), equipped only with a turbine, does not have the above "sores".
