Remove & install:
Golf/Eos TFSI/Scirocco 3,70
Golf Plus/Passat/Eos FSI 2,20
Touran 2,90

Special Tools

  • Auxiliary drive belt tensioner locking pin – Volkswagen No.T10060A.

Special Precautions

  • Disconnect battery earth lead.
  • DO NOT turn crankshaft or camshaft when timing belt removed.
  • Remove spark plugs to ease turning engine.
  • Turn engine in normal direction of rotation (unless otherwise stated).
  • DO NOT turn engine via camshaft or other sprockets.
