Hi People,
C3 1.4 HDi 06 plate 46k on the clock - The engine management light keeps coming on and going off at random intervals - ERG valve has been replaced, when you plug a diagnostic reader in it does not come up with any fault codes?

Any ideas ?

I would think that the code reader you are using is not up to the job. MIL light will leave a code ore more than one. For full coverage of your HDi engine and its codes try one of these lexia clones. There is a post with some information about lexia in this topic. Its a bit more advanced than a standard OBD2 reader and runs from a laptop/PC but will cover all the fault codes the HDi engines can throw at it.
