How To Diagnose A Problem In A...?

Question

2004 Renault Megane

Does anyone know how you enter the test mode?

The thing that makes the dials go all weird

I need to identify a fault

I have the list of the codes and their meanings

Just need to get the car to tell me what's wrong

No I don't necessarily need an OBD II Tool

Answer 1

cant tell you, looks like you have a jaguar

Answer 2

Sorry, but you do need an OBDII tool - you can't access fault codes by bridging links on the DLC of the 2004 Megane, the instrument test is unrelated, and accessed by holding both start & computer buttons with ignition on.
