Rattling noise from the engine bay on a VW Golf VI
FAULT:
We have a 2012 Volkswagen Golf 2L GTI in the workshop, and the customer is complaining of a rattling noise from the engine bay when driving at 1,800- 2,900rpm. We have heard the rattling noise on a road test but cannot recreate the fault in the workshop. Are you aware of a rattling noise from the engine on this model?
FIX:
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 wastegate regulating valve control rod and the exhaust manifold flap arm. Fit a spring clip to the turbocharger wastegate regulating valve control rod (Fig 2). Carry out road test to ensure the rattling noise has been eliminated.
