VW Passat 2002 V6 Error P0442 and Pending P0139 - How to Diagnose and Fix
Hi there, I'm experiencing error code P0442 with a pending P0139 on my 2002 VW Passat V6. The gas cap is original and makes a clicking sound. What should I check next or what steps should I take to resolve this issue? Any advice would be greatly appreciated. Thanks, Mandy
