determined, the Vehicle Identification Number (VIN) has been altered and cannot be determined,
and/or the
Applicable covered vehicle components were previously replaced with used or salvaged
automobile parts.

(included in Repair Instruction 11 31 054), specifically states to release the screws for the wastegate
actuator and to raise up the unit slightly to gain access to the chain tensioner.
This instruction will avoid wastegate actuator and turbocharger removal. Do not remove the entire
wastegate actuator and or the turbocharger for any reason while replacing the engine oil pump drive chain
module, timing chain, timing chain tensioner, slide rail, tensioning rail and guide rail.
Change the engine oil and filter.
