Between 1998 and 2000, a plant in Austria assembled the 1.2-liter Opel X12XE or LW4 engine, which was part of the GM Family 0 engine series and changed its index to Z12XE during the switch to Euro 4. The engine was installed on basic modifications of popular models like the Astra G or Corsa B.
X12XE, X14XE, X16XEL, X16SZR, X18XE, and X18XE1 are all part of the X10 line.

Disadvantages of the X12XE engine
Although this unit is dependable, it cannot withstand poor-quality oil and lengthy replacement intervals.
As a result, they complain about lubricant coking and hydraulic compensator sticking on specialized forums.
After 200,000 kilometers, the oil pump’s performance frequently declines due to its small size.
The timing chain frequently needs to be replaced before 100,000 kilometers due to its short service life.
The ignition module and thermostat are also weak points in this power unit.
