Camshaft Position Timing Over-Advanced (Bank 1)
What it means

Can you keep driving?
Short distances OK. Rough running and hard starts are common symptoms.
Common causes

⚠️ Don't get ripped off
Check the cheap stuff first: correct oil weight and a fresh filter fix a real share of VVT codes. A timing chain quote without checking oil condition first is premature.
