18209 - Service Update. Certain vehicles equipped with a 1.6L diesel engine (RPO LH7), may have been built with an improper alignment of the clamp/gasket assembly connecting the turbocharger to the catalytic converter. This condition may cause a diesel exhaust leak and/or smoke from the underhood area of the vehicle. In addition, a check engine indicator may set with diagnostic trouble code P0421. Dealers are to inspect and replace the turbocharger to catalytic converter clamp/gasket as necessary.
