Faults, breakdowns and problems of the EC5 engine
Weak catalytic converter
The most famous engine problem is a weak catalytic converter and if you pour anything into the tank, it can fall apart already by the mileage of 100-150 thousand km. After removing the catalytic converter there is usually oil consumption up to 1.5 liters per 1000 km.
Oil consumption
The oil consumption in this unit can appear even with a fully working catalytic converter, as compared to the TU5 motor, the rings are thinner here and they lie down faster.
Breakage of the timing belt
According to the regulations, the timing belt is changed every 120 000 km, but it does not always serve so long, and compliance with the dealer’s recommendation may result in its breakage and bending of valves.
Other shortcomings
Also regularly occur floating revolutions due to contamination of the throttle unit, and not very reliable ignition coils here combined into a single and not cheap unit.
The manufacturer stated the EC5 engine life at 200,000 km, but it easily goes 400,000 km.
