VEHICLE: Volkswagen Golf VI
ISSUE: Rattling noise from engine bay when driving at 1800-2900 rpm
DIAGNOSIS & SOLUTION:
We have a 2012 Volkswagen Golf 2,0 GTI in the workshop and the customer is complaining of a rattling noise from the engine bay when driving at 1800-2900 rpm. We have heard the rattling noise on road test but cannot recreate the fault in the workshop. Are you aware of a rattling noise from the engine on this model?
We are aware of several Volkswagen models with engine codes CCZA/CCZB/CCZC/CCZD suffering with the noise you have described. The rattling noise is due to excessive play between the turbocharger (TC) wastegate regulating valve control rod and the exhaust manifold flap arm. Fit a spring clip, available from Volkswagen parts department, to the turbocharger (TC) wastegate regulating valve control rod (fig. 1.1.). Carry out road test to ensure rattling noise has been eliminated.
