they wont touch a z22se registered over 5 years ago thus meaning no more warranty work, the later 2.2's had the modified chain kits
this came from my m8 who works in warranty analysis luton, he had a list of of everything that goes wrong with the 2.2 vectra b's, ranigng from the irmscher letterbox that leaks from the welds and has baffle problems and EGR problems that are not rectified even though the sensor is changed
