Renault Trouble Codes and Known Issues

Renault is very popular in Latin America and Europe with the Logan, Sandero, Duster, Kwid, Clio and Megane. Its K4M and K7M gasoline engines and the K9K diesel are simple to repair; the DP0 (AL4) automatic transmission, used for years in the Clio, Megane, Logan and Sandero, accounts for many of the questions.

Common problems on Renault vehicles

• Crankshaft position (TDC) sensor on the K4M and K7M.
• DP0 / AL4 automatic transmission: pressure solenoid and harsh shifts.
• EGR valve and intake manifold clogged with carbon on the K9K diesel.
• Body grounds and connectors, which set U codes.
• Ignition coils on 1.6 16v engines.

Tips for diagnosing a Renault

• On the DP0 transmission, changing the fluid and the pressure solenoid fixes many cases before the gearbox has to come out.
• After replacing the battery or the computer, some Renaults need the throttle body initialized with a scan tool.
