The EGR valve on the Fiat 500 should be cleaned every 50,000 miles or before. Residue in the valve can build up over time and will need clearing. If not, the problems listed below may arise.

D.I.Y. EGR Valve Cleaning

  • If the valve has a vacuum hose, disconnect the hose and check for degradation. Check all other attached hoses for wear and tear.
