Opel Ampera Ampera

Solid 1.4-litre turbopetrol engine from the GM era with good power output, but several known weak points. Piston ring damage and crankcase ventilation are the classic problems leading to elevated oil consumption. With well-maintained examples using correct oil (Dexos1 Gen2) and regular intervals it is reliable – pre-purchase inspection for blue smoke and turbo condition recommended.

• !! Piston ring land fractures and high oil consumption from 90,000 km

  Prematurely worn or fractured piston ring lands cause elevated oil consumption. Misdiagnosis often leads to unnecessary turbo or crankcase ventilation replacement without effect.

  Symptoms: Blue smoke from exhaust, oil consumption above 0.5 l/1,000 km, oil sludge under filler cap, possible catalytic converter damage.

• !! Turbocharger blowing oil into intake from 100,000 km

  The turbocharger pushes oil into the intake tract and intercooler. Often caused by a failed membrane in the valve cover crankcase breather or a worn turbo bearing.

  Symptoms: Oil film in intake and intercooler, blue or white smoke on acceleration, fault code P0299, power loss.

• !! Water pump failure from 80,000 km

  Water pumps fail early, sometimes before 50,000 km. Failure risks overheating and engine damage. Noise or whistling often precedes the fault.

  Symptoms: Squealing or whistling from the engine bay, coolant temperature rises abnormally, coolant loss.
