Known issues

Most frequent / serious themes first; amber labels mark year gates.

Overheating

Often reported

This is a reliable unit and owners more often complain about noise and vibrations than breakdowns, but it absolutely does not tolerate overheating. If you do not keep the radiators clean, all gaskets and seals will harden, and then lubricant will leak from all cracks.

Timing chain stretch

Often reported

The timing chain here is quite thin, but with a careful owner it lasts up to 200,000 km, however with excessively active use it can stretch before 100,000 km. The replacement procedure is inexpensive if the expensive phase adjusters do not need updating.

Other shortcomings

Often reported

This unit has an aluminum block with an open cooling jacket and oil consumption due to cylinder distortion is not uncommon here, especially around 200-250 thousand km. Also weak points include an unreliable adsorber valve and short-lived mounts.
