Known issues

Oil consumption

Often reported

Most complaints on the specialized forum are related to progressive oil consumption. It appears near 200,000 km after wear of oil scraper rings and valve stem seals. If replacement does not help, boring cylinders is problematic due to thin walls.

Timing belt breakage

Often reported

According to regulations, the timing belt is replaced every 90,000 km, but it may break earlier, causing valve bending. Usually the cause is non-original parts or a seized water pump, which is driven by the same belt.

Floating idle speed

Often reported

Owners often face unstable engine operation. The main culprits are air leaks through hoses or intake, heavy contamination of the idle air control valve, or failure of the throttle position sensor.

Other shortcomings

Often reported

Also common are oil leaks from valve covers and heat exchanger, leaking injectors, and warping of the exhaust manifold mating surface. For hesitant starts, check the fuel pressure regulator filter and ECU firmware.
