Disadvantages of the Audi ABK engine

  • This motor is rightfully considered one of the most reliable in the class and rarely breaks down.
  • The cause of unstable operation is usually a dirty idle speed controller or sensor failures.
  • Also, some components of the ignition system regularly fail here.
  • The timing belt changes every 90 thousand km, when it breaks, the valves most often do not bend.
  • After 200,000 km of run, an oil burner and knocks of hydraulic lifters are often found.

  1. PS. Higher oil comsumption (even pretty high) can be sometimes caused by old hardened valves’ steam seals – in case of at least decent condition of piston-cylinder sets (don’t need to be perfect).

  2. From experience – this engine and from collected informations some to event most of the EA827 family tending to have worn out auxiliary shaft bearings in higher mileages achieved, manufacturer does not predict to replace them (no OEM spare parts), but replacements are coming with help, with longitudinally located engine repair is not a big problem, by the way we can change oil pump with rods’ and crakshaft’s bearings – if shaft surfaces are not bad it is possible to do without extra disassembly – all to do in vehicle.
    With proper care is the long lasting engine.
